Bardick Snake (Echiopsis curta)

The bardick is a small snake found in leaf litter and among vegetation debris in semi-arid areas of the southern part of the continent. It is grey or grey-brown in colour and typically grows to no mre than about 60cm in length. The head is distinct, being broader tha the neck. It preys on small lizards, frogs and small mammals. Its venomous status is uncertain, but the venom has been found to have similarities with death adder venom. Females produce a litter of between 3 and 14 live young.

Description

The Bardic Snake is an evil Yuan-Ti character. The Yuan-Ti are known as a deceitful and controlling race, and so the idea of one who would sing lies in order to weaken an enemy is fitting, as is the Bard's use of enchantment spells to control enemies. This particular Yuan-Ti is also an experienced veteran warrior and has dabbled in necromancy (hence the Blackguard and Pale Master levels). Because of these factors, this particular build has very solid role-playing qualities. However, it is made also as a power build designed to gain both Epic Divine Might and Hymn of Requiem while achieving high saves, spell resistance, and AC as well as significant power with enchantment spells. It is extremely versatile, with countless options for how to approach a battle. As such, there are very few types of enemies that this character is hard-pressed to deal with. In fact, this build tested favorably against most builds I tested it against in the Battle of the Builds mod. This is remarkable considering 1v1 completely ignores the important party buffing aspect of Bards.

Part of the aim of this build is versatility. It is fun to have multiple viable options on how to approach a battle. The Bardic Snake can approach things in a lot of different ways. He can be use epic divine might to be a major melee damage dealer. He can pump up his defense with inspirations, songs, and spells to become a tank. He can debuff opponent's will saves and then throw out hard to resist enchantment spells. He can throw down a series of bombs like curse song, hymn of requiem, and ice storm and watch like a Wizard or Sorcerer does as his party mops up the severely weakened/damaged enemies. Inspire Regeneration can make him a poor man's cleric between battles. Pumping up Hide and Move Silently (which I dont do, but is certainly possible) and using inspire competence or using invisibility can make him a good scout. Inspire competence in conjunction with sleight of hand or appraise or a conversation skill can get you things you want more easily. With a high Use Magic Device, your battle options extend to any arcane OR divine spell that can be found on a scroll or wand! The Bardic Snake will also be the major buffer for your party like any other Bard. The options are just endless with this character! You can be creative too. For instance, I recently discovered that with NWN2s dumb AI, it is a legitimate strategy to use Inspire Slowness and then have your Bard run in and draw all the aggro of a group. He can run around without getting caught while the rest of your party gets easy attacks of opportunity and sneak attacks on the chasing enemies without taking damage. If your party's health is too low to win a battle head on, this Bard tactic can be a lifesaver. Anyways, let's get down to the essentials:


Range

E. curta ranges from southern Western Australia through South Australia, and west to Victoria and New South Wales. It is listed as Near Threatened by the IUCN..

Habitat

E. curtis inhabit semiarid grasslands and shrublands. They are usually found under rocks, debris, fallen vegetation, etc.

Food and Venom

The species is nocturnal. They prey upon a wide variety of rodents, lizards, amphibians, and sometimes birds and insects- an unusual variety for a small elapid. These snakes are venomous, and, like all elapids, inject their venom swiftly through fangs placed in the front of the jaw.

Reproduction

Little is known about either of these snakes' reproductive habits except that Bardicks are ovoviviparous, and that females give birth to anywhere from 3-14 young around August.

Most Venomous Snakes in the World

 1.Taipan (Oxyuranus scutellatus): It is one of the most venomous and deadliest snakes in the world. There are three main sub-species of Taipan such as Papuan Taipan (Oxyuranus s. canni), Western or Inland Taipan (Oxyuranus Microlepidotus) or (Fierce Snake) and Common or Coastal Taipan (Oxyuranus Scutellatus). Taipans are found in Australia and New Guinea. Fierce snake or Inland Taipan is more toxic as compared to Papuan Taipan and Coastal Taipan. Inland Taipan is olive or brown in appearance, with uniformly black head or black marking on the head. Its habitat is grasslands and dry plains. Common or Coastal Taipan is dark or light brown in color with a paler shade on the sides and underside and lightly keeled scales. It is about 6 ft in length. It is found in the open woodlands and forests.

 2. Krait: This highly poisonous snake is found in Asia. It appears black or bluish-black in color with a white narrow cross-bands and a narrow head. Its average length is about 90cms. It is more active at night than during the day. It is 15 times more deadly than the common cobra. Its venom is a powerful neurotoxin, which causes the respiratory failure.
 
3. King cobra: It is world's largest venomous snake. Its average length is about 3.5 meters and it can be maximum 5.5 meters long. It appears uniformly brown, olive or green in color with black cross-bands. King cobra is commonly found in Southern China, Thailand, Philippines, South India and Malaysia Peninsula. Its venom is a neurotoxin type.
 
4. Russell's viper: Russell's viper is more commonly found in India, Sri Lanka, Malaysian Peninsula, Southern China, Sumatra, Java, Borneo and surrounding islands. It has a light brown body with three rows of black or brown splotches having white or yellow border. Its average length is about 1 meter. It is responsible for relatively more human deaths than any other types of venomous snake. While attacking, it coils tightly, hisses and strikes with such a high speed that its victim gets little chance to escape. Its venom is of hemotoxin type, which is a powerful coagulant, causing damage to blood cells and tissues.
  
5. Black Mamba: It is Africa's most feared venomous snake. It is found in Africa's open woodlands and African savannas. It is highly toxic and notoriously aggressive. Its venom is a powerful neurotoxin. It appears uniformly black or brown. Its average length is about 4.3 meters. Its mouth has a black internal lining. It is known as world's fastest land snake with the top speed of 16-19 km/hr.

 6.Tiger snake: It is olive or dark brown in color with olive or yellowish belly and cross-bands. Its subspecies are found in Victoria and Tasmania and it is uniformly black. Its average length is about 1.2 to 1.8 meters. It is one of the most venomous snakes found in Australia. It is also found in New Guinea, Tasmania and Bass Strait Islands. Its venom is a potent neurotoxin that affects the central nervous system. It produces venom in high quantities, with an average yield of about 35 mg to 180 mg.
  
7. Western Brown Snake (Pseudonaja nuchalis): It is found in the grasslands, forests, deserts and gravelly plains. It is a native of Australia. It has a narrow black head and black neck. It may be black or light brown in color with narrow dark crossbars or a series of lighter bands around the body. It is about 1.5 meters in length. Its venom is neurotoxic.

Rosy boa

The Rosy Boa (Lichanura trivirgata) is a snake of the Boidae family, one of only two members of that family native to the United States. The other is the Rubber Boa (C. bottae). Rosy Boas are native to the American Southwest, and Baja and Sonora Mexico.

Description

These small attractive snakes attain a length of 39 in (1 m) (though some specimens from the coast of California reach 4 feet) and a large adult has a body width about the diameter of a golf ball. Coloration in Rosy Boas is highly variable. The common name is derived from the rosy or salmon coloration that is common on the belly of Rosy Boas originating from coastal southern California and Baja Mexico. Most Boas do not have this ventral coloration but instead have a series of dark to orange spots on a light-colored background.

Almost all Rosy Boas have at least some trace of three longitudinal stripes, one down the center of the back, and two on the lower sides. The appearance of these stripes varies widely from extremely straight and having high contrast with the interspaces to extremely broken with almost no contrast with the interspaces. Stripe colors can be orange, maroon, rust, brown, or black. The interspaces range from shades of light to dark gray, yellow, or tan.

Geographic range

The Rosy Boa is found in the southwestern United States in the states of California and Arizona, and northwestern Mexico in the states of Baja California and Sonora. In California, the Rosy Boa ranges throughout the Colorado and Mojave deserts and also occupies the coastal areas of Los Angeles, Orange, Riverside, and San Diego counties. In Arizona, the Rosy Boa occupies the Mojave desert and the western areas of the Sonoran desert. It is absent from the eastern and northern halves of the state. In Sonora, the Rosy Boa ranges from the border with the United States south throughout the Sonoran Desert to at least as far south as Ortiz. In Baja California, the Rosy Boa is almost ubiquitous ranging throughout the entire peninsula except in areas of extremely dry or rockless desert.

Behavior

Rosy Boas spend most of their lives concealed beneath rocks and in crevices to escape the elements and natural predators. Granite outcroppings are the most common geologic association inhabited by the Rosy Boa. Less often they are found in association with volcanic or other rock types. Only in rare places do Rosy Boas inhabit rockless environments. In areas with few rocks Rosy Boas will use rodent burrows for concealment.


Rosy Boas' activity season follows local weather patterns; however, they are generally dormant during the winter, and active during the spring, summer and fall. Like all snakes, they are dependent on external temperatures to promote such normal bodily functions as digestion and gestation. Throughout most of their range the winter is too cold for these functions and the Rosy Boas go into a dormant state called brumation. The spring is breeding season for Rosy Boas, resulting in their highest rate of activity. Most Rosy Boas are encountered in spring as they leave the security of their rock piles and crevices to seek mates. Another reason Rosy Boas may be active on the surface of the ground is to find prey or new territory.


The surface activity of Rosy Boas can take place during any hour of the day, but during hot weather they are primarily nocturnal. In the spring, they are often abroad in the afternoon and early evening. In the late spring and summer, this activity period switches to from dusk to late into the night. Because most populations of Rosy Boas live in exceedingly dry habitats, their activity is often highly moisture dependent. During dry periods they remain deep underground to assist in remaining hydrated. Recent rainfall often results in a flurry of surface activity.

These snakes forage mainly for small mammals but have occasionally been known to take other prey items such as birds and lizards. Pack rats, baby rabbits, deer mice, and kangaroo rats make up a large portion of their diet. Rosy Boas are one of the slowest-moving species of snake in the world. They are unable to pursue prey and must either wait in ambush or stalk their meals. When a meal is within reach, usually a few inches, a Rosy Boa will strike with surprising speed and accuracy. Prey is secured with tiny rows of needle-sharp teeth, then suffocated through constriction.

Rosy Boas are extremely docile when encountered by humans. When disturbed they usually roll into a compact ball with the head in the center.[1] The species is not prone to bite in defense, and when human bites have occurred they have usually been the result of a feeding response with a captive animal. All Rosy Boa bites are nonvenomous. Their extreme docility and their attractive coloration have made Rosy Boas very popular with herpetoculturists.

Reproduction
Rosy Boas bear live young, about six in a brood. The newborns are about 30 cm (12 in.) in length.

In captivity
Their generally docile temperament, ease of care, and small size makes the Rosy Boa an ideal choice for a pet snake (or first boa). They are frequently captive bred, and readily feed on commercially available mice. Many color variations are available, including albinos as well as the many different subspecies that come in dozens of variations. With other species, such as corn snakes and ball pythons, dominating the majority of the market, the popularity of Rosy Boas hasn't been as high as the other more popular species.

Baird's Rat Snake

Pantherophis bairdi is a harmless colubrid species found in the United States in the Big Bend region of western Texas, as well as in northern Mexico in Coahuila, Nuevo León, and Tamaulipas. The species was named in honor of the American zoologist Spencer Fullerton Baird. No subspecies are currently recognized.


Description

Adults can reach 25 to 55 inches in length. The color pattern consists of an orange-yellow to bright yellow, or a darker salmon ground color, overlaid with four stripes that run from the neck to the tail. The belly is generally gray to yellow, darkening near the tail.

The primary diet consists of rodents, although they will also prey on birds. Juveniles often eat lizards. They are typically more pleasantly tempered than other rat snake species. They are oviparous, laying a clutch of up to 10 eggs that takes about 3 months to hatch. Prefers semi-arid, rocky habitats.

Interesting facts about snakes...

• Snake’s scales are made up of something called Keratin, which is the same thing that our fingernails are made from.
• Mother Pythons will coil themselves around their eggs and make their bodies shiver in order to heat herself up and keep her eggs warm until they hatch. 
• The biggest snake is the Reticulated Python. It can grow up to 10.05 meters or 33 feet long! 
• The thickest snake is the Anaconda. The biggest one found measured 111 centimeters or 44 inches around. That's huge! 
• The Thread snake is the smallest snake. It is only about 10 centimeters (4 inches long) and the size of a toothpick. 
• Vine snakes are remarkable because they appear to have binocular vision. 
• Many Zookeepers believe that Cobras are faster learners than other snakes. They are able to tell the difference between their trainer and strangers.
• The ancient Greek god, Asklepios, was thought to be a healer of the sick and injured. People would take an offering to the temple and wait for Asklepios to, either come to them in their dreams or send his servants, the snake, to help them. One touch of the forked tongue was all they thought they needed to heal them. The healing snake was the Aesculapian snake. The Romans would bring this snake into their temples rather than the Greek healers.  To this day the Aesculapian snake forms part of the symbols representing physicians and veterinarians. 
• This would be funny to watch! The Hognose, Grass snake and the Spitting Cobra will fake death when feeling threatened. They flip into their backs, open their mouths, and let their tongue flop out. And they will let out some smelly stuff from their anal gland. Nobody would want to eat it after that!
• A reticulated python, named Colossus, was the largest snake that ever lived in a zoo. She lived at the Pittsburgh Zoo in Pennsylvania. Clifford Pope, the author of a book entitled “The Giant Snakes” reported that she was 22 feet long when she was captured in what is now Thailand in 1949. Eight years later she grew to 8.69 m (28 ½ feet) long. Her body was 69 cm (37 ½ inches) around and her weight was around 145 kg (320 pounds).
•  Snakes are more closely related to lizards than to other reptiles, and probably evolved from a single group of lizards. Curiously, they probably did not evolve from the group of legless lizards.
•  In ancient Greece, the sick and injured sought the aid of the god of healing and medicine, Asklepios. They took an offering to the temple and waited for the god to come to them in their dreams, or to send his sacred servants, the snakes. Ancient writings tell of the snakes healing with a touch of the tongue. The snake in question was the Aesculapian snake. The Romans chose to import this snake to their own temples, rather than to bring in Greek healers. The snake today forms part of the symbol of physicians and veterinarians (the snake is wrapped around Asklepios' staff), linking snakes to millennia of healing and medical practice.
• The hognosed snake (Heterodon sp.), grass snake and the spitting cobra can feign death by flipping on to their backs when threatened. They open their mouths, allow their tongues to loll and can empty a foul smelling substance from their anal glands, making them highly unappetizing to any potential predator.
•  Many snakes, such as vipers, boas and pythons have temperature-sensing organs on their heads. These heat pits are sensitive to changes in temperature of as little as 0.002 degrees Celsius, and effectively allow the snake to navigate and hunt in the dark.
•  Snakes can have over 300 pairs of ribs.
•  Snakes turn “blue” before a shed. This opaque change to the skin is actually due to the presence of a lymph-like layer of fluid between the old and new skins, prior to the shed of the old skin.
•  Reports of the longest, heaviest and oldest reptiles abound. Many cannot be verified. A reticulated python, shot in Indonesia in 1912, was said to be 32 feet 9 1/2 inches in length. One Burmese python weighed in at over 400 pounds. Although seldom as long as the giant pythons, the green anaconda is a heavier snake. Sir Percy Fawcett is said to have killed an anaconda measuring 62 feet in 1907, in Brazil. Since the early part of the last century, the New York Zoological Society has offered a reward of $50,000 for the capture of a live snake greater than 30 feet in length. The oldest recorded snake is a boa constrictor named Popeye, who died in 1977 at the age of 40 years, 3 months and 14 days.
•  The smallest snake may be the Martinique thread snake (Leptotyphlops bilineatus), which does not grow any bigger than 4 1/4 inches.
•  A snake's internal organs, although superficially different, have basically the same functions as those of a mammal. The difference lies in their arrangement. They are placed one after the other, to accommodate the tube-like body. All snakes have a right lung and associated air sacs that extend most of the way to the vent. In most species, the left lung is considerably shorter, or even missing.
•  The glottis, which is the entry to the trachea (breathing tube), can move to either side, to allow the snake to swallow prey. This is the tube you see when you look at the floor of a snake's mouth. Cartilage around the opening of the tube closes to prevent food from entering the respiratory tract, and produces the classic “hiss” in many snakes.
•  A snake's heart can slide 1 to 1 1/2 times its length from its normal position, to allow the passage of swallowed prey. This is because of the relative mobility of the pericardial sac, which surrounds the heart.
•  Venom glands have evolved independently in several species. Venoms are very complex substances, which may consist of a dozen or more toxic components. These can include substances poisonous to the heart, nerves and DNA as well as enzymes that break down natural tissue barriers, allowing the spread of venom within the body.
•  Spitting cobras can inject venom in their bites, but can also force venom out, under pressure, through tiny channels in their fangs. Raising the front half of its body, the snake can aim venom at the eyes and mucous membranes of its target, over 3 feet away.
•  Snakes have two rows of teeth on the top jaw, one row on the bottom jaw. The teeth, including fangs, in most cases are replaced throughout life.
•  When the tongue is in the mouth, it lies in a sheath beneath the glottis with its tip touching the vomeronasal or Jacobsen‘s organ. This is an organ of smell, so when your snake flicks out his tongue, he is, in fact, “tasting” or smelling the air. The forked design allows the snake to detect on which side the smell is strongest, and so to locate his prey, even in the dark.
•  The Brahminy blind snake are all females. When mature, they lay fertile eggs, and the young are clones of the mother. Although native to Asia, this snake is now found in warm countries all over the world.
•  The Emerald tree boa is born red or yellow, and changes to green after about a year.
•  The rattlesnake's rattle consists of six to 10 layers of scales, which fail to shed and make that distinctive sound when the tail is shaken as a warning. Eventually the older segments will slough as the rattle lengthens.
•  The tail of the Calabar ground boa is blunt, cylindrical and has white scales on the underside, and altogether appears very much like a head. When threatened, the snake coils into a ball, hides its head, leaving the less vulnerable tail exposed to confuse predators.
•  The common egg eater (Dasypeltis scabra) is a highly specialized snake. Although it is not venomous, the markings are sufficiently similar to those of the deadly cobra or viper that a potential predator will think twice before attacking. The egg eater can also expand its jaws to mimic the larger head of the venomous. To consume an egg, the jaws can expand to four or five times the size of the egg. Once engulfed, the egg is pierced by two specialized vertebrae. Other modified bones in the vertebral column stabilize it, prevent its slipping out of the mouth or further into the snake. Yet another set of unique vertebrae crush the egg. Once emptied of its contents, the shell is regurgitated.
•  The black mamba (Dendroaspis polylepsis) is brown, gray or olive, but never black. It is a particularly dangerous snake, with a bite that kills 95 to 100 percent of victims. The black mamba may also be the fastest snake, reaching speeds of 10 to 12 miles per hour. Other particularly dangerous snakes include the common krait, Russell's viper (both Asian snakes) and the taipan (Australian). Seven of the 10 most deadly snakes live in Australia.
•  Snakes move by relaxing and contracting muscles lengthwise along the body. Sidewinding is a specialized form of motion that allows a snake to travel with speed and relatively little expenditure of energy along loose desert sand. The snake lifts a loop of its body from the surface, using its head and tail. The loop is moved sideways and then back to the ground. This creates the typical series of unconnected parallel tracks.
•  The paired claw-like structures seen on either side of the vent of a snake such as a ball or royal python, are in fact, remnants of the legs present in the animals from which the modern species has evolved.

Gaboon viper (Bitis gabonica)

    Common names: Gaboon viper, butterfly adder, forest puff adder, swampjack,[2] (more).

Bitis gabonica is a venomous viper species found in the rainforests and savannas of Sub-Saharan Africa.[1] This is not only the largest member of the genus Bitis,[3] but also the world's heaviest viperid[2] and it has the longest fangs (up to 2 inches),and the highest venom yield of any venomous snake.[2] Two subspecies are currently recognized, including the nominate race described here.[4]

Description

Adults average 122–152 cm (4 to 5 feet) in length with a maximum of 205 cm (81 in) for a specimen collected in Sierra Leone. The sexes may be distinguished by the length of the tail in relation to the total length of the body: approximately 12% for males and 6% for females. Adults, especially females, are very heavy and stout. One female had the following dimensions:[2]


Total length     174 cm (69 in)
Head width     12 cm (4.7 in)
Girth     37 cm (14.65 in)
Weight (empty stomach)     8.5 kg (19 lbs)



In their description of B. gabonica, Spawls et al.. (2004) give an average length of 80–130 cm (32 to 51.5 in), with a maximum size of 175 cm (69.3 in), saying the species may possibly grow larger still. They acknowledge reports of specimens over 6 feet (1.8 m), or even over 2 m (6.5 ft) in length, but claim there is no evidence to support this.[5]

The head is large and triangular, while the neck is greatly narrowed: almost one-third the width of the head.[2] A pair of horns is present between the raised nostrils — tiny in B. g. gabonica, but much larger in B. g. rhinoceros.[5] The eyes are large and moveable,[2] set well forward,[5] and surrounded by 15–21 circumorbital scales.[2] There are 12–16 interocular scales across the top of the head. 4–5 scale rows separate the suboculars and the supralabials. There are 13–18 supralabials and 16–22 sublabials.[2] The fangs may reach a length of 55 millimetres (2.2 in) :[3] the longest of any venomous snake.[2]

Midbody, there are 28–46 dorsal scale rows, all of which are strongly keeled except for the outer rows on each side. The lateral scales are slightly oblique. The ventral scales number 124–140: rarely more than 132 in males, rarely less than 132 in females. There are 17–33 paired subcaudal scales: males have no fewer than 25, females no more than 23. The anal scale is single.[2]

The color pattern consists of a series of pale, sub-rectangular blotches running down the center of the back, interspaced with dark, yellow-edged hourglass markings. The flanks have a series of fawn of brown rhomboidal shapes, with light vertical central bars. The belly is pale with irregular brown or black blotches. The head is white or cream with a fine, dark central line, black spots on the rear corners, and a dark blue-black triangle behind and below each eye.[5] The iris color is cream, yellow-white, orange[5] or silvery.[6]

Habitat

The Gaboon viper is usually found in rainforests and nearby woodlands, mainly at low altitudes,[6] but sometimes as high as 1500 m.[2] Spawls et al. (2004) mention a maximum altitude of 2100 m.[5] According to Broadley and Cook (1975), it is generally found in environments that are parallel to those occupied by its close relative, B. arietans, which is normally found in more open country.[9]

In Tanzania, this species is found in secondary thickets, cashew plantations, and in agricultural land under bushes and in thickets. In Uganda, they are found in forests and nearby grasslands. They also do well in reclaimed forest areas: cacao plantations in West Africa and coffee plantations in East Africa. They have been found in evergreen forests in Zambia. In Zimbabwe, they only occur in areas of high rainfall along the forested escarpment in the east of the country. In general they may also be found in swamps, as well as in still and moving waters. They are commonly found in agricultural areas near forests and on roads at night.[2]

Venom
Bites are relatively rare, due to their docile nature and the fact that their range is mainly limited to rainforest areas.[3] Due to their sluggishness and unwillingness to move even when approached, people are often bitten after they accidentally step on them, but even then in some cases they may not bite.[11] However, when a bite does occur it should always be considered a serious medical emergency. Even an average bite from an average sized specimen is potentially fatal.[3] Antivenom should be administered as soon as possible to save the victim's life if not the affected limb.[9]

The snake's hemotoxic venom itself is not considered particularly toxic based on tests conducted in mice. In mice, the LD50 is 0.8–5.0 mg/kg IV, 2.0 mg/kg IP and 5.0–6.0 mg/kg SC.[12] However, the venom glands are enormous and each bite produces the largest quantities of venom of any venomous snake. Yield is probably related to body weight, as opposed to milking interval.[2] Brown (1973) gives a venom yield range of 200–1000 mg (of dried venom),[12] A range of 200–600 mg for specimens 125–155 cm in length has also been reported.[2] Spawls and Branch (1995) state that from 5 to 7 ml (450–600 mg) of venom may be injected in a single bite.[3]

A study by Marsh and Whaler (1984) reported a maximum yield of 9.7 ml of wet venom, which translated to 2400 mg of dried venom. They attached "alligator" clip electrodes to the angle of the open jaw of anesthetized specimens (length 133–136 cm, girth 23–25 cm, weight 1.3–3.4 kg), yielding 1.3–7.6 ml (mean 4.4 ml) of venom. Two to three electrical bursts within a space of five seconds apart were enough to empty the venom glands. The snakes used for the study were milked 7 to 11 times over a 12-month period, during which they remained in good health and the potency of their venom remained the same.[2]

Based on how sensitive monkeys were to the venom, Whaler (1971) estimated that 14 mg of venom would be enough to kill a human being: equivalent to 0.06 ml of venom, or 1/50–1/1000 of what can be obtained in a single milking. Marsh and Whaler (1984) wrote that 35 mg (1/30 of the average venom yield) would be enough to kill a man of 70 kilograms (150 lb).[2] Branch (1992) suggested that 90–100 mg would be fatal in humans. Further investigation is needed.

In humans, a bite causes rapid and conspicuous swelling, intense pain, severe shock and local blistering. Other symptoms may include uncoordinated movements, defecation, urination, swelling of the tongue and eyelids, convulsions and unconsciousness.[2] Blistering, bruising and necrosis may be extensive. There may be sudden hypotension, heart damage and dyspnoea.[5] The blood may become incoagulable with internal bleeding that may lead to haematuria and haematemesis.[3][5] Local tissue damage may require surgical excision and possibly amputation.[3] Healing may be slow and fatalities during the recovery period are not uncommon.[5]

RING-NAKED SNAKE (Diadophis punctatus)

The ringneck snake or ring-necked snake (Diadophis punctatus) is a colubrid snake species. It is found throughout much of the United States, central Mexico, and south eastern Canada[2]. Ring-necked snakes are secretive, nocturnal snakes that are rarely seen during the day time. They are slightly venomous but their non-aggressive nature and small rear-facing fangs pose little threat to humans who wish to handle them. They are best known for their unique defense posture of curling up their tails exposing their bright red-orange posterior, ventral surface when threatened. Ring-necked snakes are believed to be fairly abundant throughout most of their range though no scientific evaluation supports this theory. Scientific research is lacking for the ring-necked snake and more in-depth investigations are greatly needed[3]. It is the only species within the genus Diadophis, and currently fourteen subspecies are identified, but many herpetologists question the morphologically-based classifications[4].
The Northern Ringneck Snake is a smallish snake, only growing up to two feet long. It is bluish-black in color, with a yellow or red ring around its neck, and a matching belly. This snake has a large, flat head.Northern Ringneck Snakes live just about anywhere, including forests, grassy places, and streamsides.They usually hide under logs, rocks, leaf litter, or matted plants.They are nocturnal, so they are mostly seen at night.

                                                                                  

  Physical description

Ring-necked snakes are fairly similar in morphology throughout much of their distribution.

Dorsal coloration is solid olive, brown, bluish gray to black, broken only by a distinct yellow, red, or yellow-orange neck band[2][5]. There are a few populations in New Mexico, Utah, and other distinct locations that do not have the distinctive neck band[2]. Additionally individuals may have a reduced or partially colored neck band that is hard to distinguish; coloration may also be more of a cream color rather than bright orange or red[5]. Head coloration tends to be slightly darker than the rest of the body with tendencies to be blacker than grey or olive[5]. Ventrally the snakes exhibit a yellow-orange to red coloration broken by crescent shaped black spots along the margins[2]. Sometimes individuals lack the distinct ventral coloration but typically retain the black spotting[5]. Rarely do individuals lack both the ventral or neck band coloration so use of those two characteristics are the most simple way to distinguish the species[2].

Size also varies across the species distribution. Typically adults measure 25-38 cm (10-15 inches)[2], except for D. punctatus regalis which measures 38-46 cm (15-18 inches)[5]. First year juvenile snakes are typically about 20 cm (4 inches) and grow about 2-5 cm (¾-2 inches) a year depending on the developmental stage or resource availability[5].

Ring-necked snakes have smooth scales with 15-17 scale rows at mid body[2]. Males typically have small tubercles on their scales just anterior to the vent which are usually absent in females[2].

Habitat

Ring-necked snakes occur in a wide variety of habitats. Preference seems to be determined by areas with abundant cover and denning locations spaces[5]. Northern and western species are found within open woodlands near rocky hillsides, or in wetter environments with abundant cover or woody debris[2]. Southern species exist primarily within riparian and wet environments, especially in more arid habitats[5]. Stebbins (2003) identified the species as a snake of moist habitats, identifying that moist soil conditions were the preferred substrate[2]. Ring-necked snakes are also not found above an elevation of 2200 meters[2]. In northern regions, dens are also important in identifying suitable ring-necked snake habitat. Dens are usually shared communally[5], and are identifiable by an existent subsurface crevasse or hole that is deep enough to prevent freezing temperatures. Since it is a woodland reptile, it can commonly also be found under wood or scraps. Because of the hot weather, they tend to make holes and burrow or they decide to hide under rocks or any suitable material. They are normally found in flatland forests.

Behavior
The diet of the ring-necked snake consists primarily of smaller salamanders, lizards, frogs, earthworms, and some juvenile snakes of other species[5]. The frequency at which prey species are chosen is dependent on their availability within the habitat[5]. Ring-necked snakes use a combination of constriction and envenomation to secure their prey. The snakes do not have a true venom gland, but they do have an analogous structure called the Duvernoy’s gland derived from the same tissue[3]. Most subspecies are rear-fanged with the last maxillary teeth on both sides of the upper jaw being longer and channeled[3]; the notable exception is D. punctatus edwardsii which is fangless[5]. The venom is produced in the Duvernoy's gland located directly behind the eye[3]. It then drains out of an opening at the rear of the maxillary tooth[3]. Ring-necked snakes first strike and then secure the prey using constriction. Next they maneuver their mouths forward ensuring that the last maxillary tooth punctures the skin allowing the venom to enter the prey's tissue[3]. Ring-necked snakes are rarely aggressive to larger predators suggesting that their venom evolved as a feeding strategy rather than a defense strategy. Rather than trying to bite a predator, the snake winds up its tail into a corkscrew, exposing the brightly colored belly[5].

Ring-necked snakes are primarily nocturnal or highly crepuscular, though some diurnal activity has been observed[5]. Individuals are sometimes found during the day, especially on cloudy days, sunning themselves to gain heat[5]. Yet, most individuals lie directly under surface objects that are warmed in the sun and use conduction with that object to gain heat[5]. Even though ring-necked snakes are highly secretive, they do display some social structure; but the exact social hierarchies have never been evaluated[5]. Many populations have been identified to have large colonies of more than 100 individuals, and some reports identify that some smaller colonies occupy the same microhabitats[5].

Reproduction
Ring-necked snakes usually mate in the spring. However, in some subspecies mating occurs in the fall, and delayed implantation occurs.[5]. Females attract males by secreting pheromones from their skin[5]. Once the male finds a female he starts by rubbing his closed mouth along the female’s body[5]. Then the male bites the female around her neck ring maneuvering to align their bodies so sperm can be inserted into the female’s vent[5]. Females lay their eggs in loose aerated soils under a rock or in a rotted log[4]. Three to ten eggs are deposited in early summer and hatch in August or September[5]. The egg is elongate with a white color contrasted by yellow ends[5]. When hatched, juveniles are precocial and fend for themselves without parental care[5].

Distribution
Ring-necked snakes are fairly common throughout much of the United States extending into Southeastern Canada and central Mexico. Eastern populations cover the entire eastern seaboard from the Gulf of Saint Lawrence continuous through the gulf coast of north Texas[5]. Distribution moves inland into northern Minnesota continuing diagonally through the US to include all of Iowa, eastern Nebraska, and most of Kansas[5]. In the western US the distribution is significantly less continuous, with spotty distinct population segments through most of the Pacific Northwest[2]. Populations extend from south-central Washington continuing along the extreme west coast into Mexico[2]. Population segments extend inland into western Idaho, through southern Nevada, into central Utah, and continuing south through Arizona and central Mexico[2
