Chrysopelea (Flying Snake)

Chrysopelea (Flying Snake)

Description:
 Chrysopelea, or more commonly known as the flying snake, is a genus that belongs to the family Colubridae. Flying snakes are mildly venomous,though they are considered harmless because their toxicity is not dangerous to humans.Their range is in Southeast Asia (the mainland, Greater and Lesser Sundas, Maluku, and the Philippines), southernmost China, India, Sri Lanka.

Habitat:
Chrysopelea ornata ornattissima is a flexible snake. It can be found in forests, on plantations, in gardens and in houses. This snake is regularly found in the inner city areas of Bangkok and Pattaya. As they feed on rodents, geckos and other lizards, they are often found on and in houses. These snakes are active during the day, can climb walls and are very fast.

Gliders:
Chrysopelea is also known under its assigned common name "flying snake". It glides by using its ridge scales along its belly,pushing against rough bark surface of tree trunks, allowing it to move vertically up a tree. Upon reaching the end of a tree's branch, the snake continues moving until its tail dangles from the branch's end. It then makes a J-shape bend,leans forward to select the level of inclination it wishes to travel to control its flight path, as well as selecting a desired landing area. Once it decides on a destination, it propels itself by thrusting its body up and away from the tree, sucking in its stomach, flaring out its ribs to turn its body in a "pseudo concave wing all the while making a continual serpentine motion of lateral undulation[9] parallel to the ground to stabilise its direction in midair in order to land safely.

The combination of sucking in its stomach and making a motion of lateral undulation in the air makes it possible for the snake to glide in the air, where it also manages to save energy compared to travel on the ground and dodge terrestrial bounded predators.The concave wing that a snake creates in sucking its stomach, flattens its body to up to twice its width from back of the head to the anal vent, which is close to the end of the snake's tail, causes the cross section of the snake's body to resemble the cross section of a frisbee or flying disc.When a flying disc spins in the air, the designed cross sectional concavity causes increased air pressure under the centre of the disc, causing lift for the disc to fly.A snake continuously moves in lateral undulation to create the same effect of increased air pressure underneath its arched body to glide.Flying snakes are able to glide better than flying squirrels and other gliding animals, despite the lack of limbs, wings, or any other wing-like projections, gliding through the forest and jungle it inhabits with the distance being as great as 100 m.Their destination is mostly predicted by ballistics; however, they can exercise some in-flight attitude control by "slithering" in the air.

venom:
If they feel threatened and cannot flee, they bite straight away. The species Chrysopelea belongs to the family of rearfanged snakes. However, the venom so mild that it does not have much of an effect on humans. 

Diet: 

Chrysopelea are diurnal, which means they hunt during the day. They prey upon lizards, frogs, birds and bats.

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.

Rattlesnake:-

Crotalus cerastes

Rattlesnakes are a group of venomous snakes of the genera Crotalus and Sistrurus[1] of the subfamily Crotalinae ("pit vipers"). There are 32 known species of rattlesnake, with between 65-70 subspecies.[2], all of which are native to the Americas - ranging from southern Alberta, and southern British Columbia Canada to Central Argentina.

Rattlesnakes are predators who live in a wide array of habitats, hunting small animals such as birds and rodents. They kill their prey with a venomous bite, rather than by constricting. All rattlesnakes possess a set of fangs with which they inject large quantities of hemotoxic venom. The venom travels through the bloodstream, destroying tissue and causing swelling, internal bleeding, and intense pain. Some species, such as the Mojave Rattlesnake, additionally possess a neurotoxic component in their venom that causes paralysis and other nervous symptoms.

The threat of envenomation, advertised with the shaking of the rattle, deters many predators. However, rattlesnakes fall prey to hawks, weasels, king snakes, and a variety of other species. Rattlesnakes are heavily preyed upon as neonates, while they are still weak and mentally immature. Very large numbers of rattlesnakes are killed by humans. Rattlesnake populations in many areas are severely threatened by habitat destruction, poaching, and extermination campaigns.

Rattlesnake bites are the leading cause of snakebite injuries in North America, and cause approximately 82% of fatalities. However, rattlesnakes rarely bite unless provoked or threatened; and if treated promptly, the bites are rarely fatal.

Range and habitat

Rattlesnakes are native to the Americas, living in diverse habitats from Southwestern Canada to Central Argentina. The large majority of species live in the American Southwest and Mexico. Four species may be found east of the Mississippi river, and two in South America. In the United States, the state with the most forms of rattlesnakes is Arizona, with seventeen species and subspecies.[5][6]

Rattlesnakes are found in almost every type of habitat that is capable of supporting terrestrial ectothermic vertebrates; but individual species can have extremely specific habitat requirements, only able to live within certain plant associations in a narrow range of altitudes. Most species live near open, rocky areas. Rocks offer them cover from predators, plentiful prey (e.g. rodents, lizard, insects, etc. that live amidst the rocks), and open basking areas. However, rattlesnakes can also be found in a wide variety of other habitats including prairies, marshes, deserts, and forests.[7] Rattlesnakes prefer a temperature range between 80 and 90°F (26-32°C), but can survive temperatures below freezing, recovering from brief exposure to temperatures as low as 4°F, and surviving for several days in temperatures as low as 37°F.[8]

Evidence has been collected to show the most probable ancestral area of rattlesnakes is the Sierra Madre Occidental region in Mexico. This same study found the most probable vegetation or habitat of the ancestral area to be pine-oak forests



Prey

Rattlesnakes consume mice, rats, small birds and other small animals[9], playing an important ecological role by limiting the size of rodent populations, which prevents crop damage and stabilizes ecosystems.[10]

Rattlesnakes lie in wait for their prey, or hunt for it in holes.[11] The prey are killed quickly with a venomous bite as opposed to constricting. If the bitten prey moves away before dying, the rattlesnake can follow it by its scent.[12][13] When it locates the fallen prey, it checks for signs of life by prodding with its snout, flicking its tongue, and using its sense of smell. Once the prey has become incapacitated, the rattlesnake locates its head by odors emitted from the mouth. The prey is then ingested head-first, which allows wings and limbs to fold at the joints in a manner which minimizes the girth of the meal.[14] The gastric fluids of rattlesnakes are extremely powerful, allowing for the digestion of bone as well as flesh. Optimal digestion occurs when the snake maintains a body temperature of between 80 and 85°F (25-29°C). If the prey is small, the rattlesnake will often continue hunting. If it was an adequate meal, the snake will find a warm, safe location in which to coil up and rest until the prey is digested.[15]

Rattlesnakes are believed to require at least their own body weight in water annually in order to remain hydrated. The method in which they drink depends on the water source. In larger bodies of water (streams, ponds, etc.) they will submerge their head and ingest water by opening and closing their jaw, which sucks in water. If drinking dew, or drinking from small puddles, they will sip the liquid either by capillary action or by flattening and flooding the lower jaw.

Venom

Most species of rattlesnakes have hemotoxic venom, destroying tissue, causing necrosis and coagulopathy (disrupted blood clotting).[30] In the U.S., some varieties of the Mojave rattlesnake (C. scutulatus) have a presynaptic neurotoxic venom component known as Mojave Type A toxin, which can cause severe paralysis.[30][31][32] C. scutulatus is widely regarded as producing one of the most toxic snake venoms in the Americas, based on LD50 studies in laboratory mice.[33]

Rattlesnake venom is a mixture of 5-15 enyzmes, various metal ions, biogenic amines, lipids, free amino acids, proteins, and polypeptides. It contains components designed to immobilize and disable the prey, as well as digestive enzymes which break down tissue to prepare for later ingestion.[25][29] The venom is very stable, and retains its toxicity for many years in storage.[25]

Older snakes possess more potent venom, and larger snakes are frequently capable of storing larger volumes of it.

Antivenom

Crotaline antivenom (or "antivenin") is commonly used to treat the effects of local and systemic pit viper envenomations.[72] The first step in the production of crotaline antivenom is collecting ("milking") the venom of a live rattlesnake - usually from the Western Diamondback (Crotalus atrox), Eastern Diamondback (Crotalus adamanteus), South American rattlesnake (Crotalus durissis terrificus), or fer-de-lance (Bothrops atrox). The extracted venom is then diluted and injected into horses, goats, or sheep, whose immune systems produce antibodies that protect from the toxic effects of the venom. These antibodies accumulate in the blood, which is then extracted and centrifuged to separate the red blood cells. The resulting serum is purified into a lyophilized powder, which is packaged for distribution and later use by human patients.[73][74]

Because antivenom is derived from horse animal, people generally display an allergic response during infusion, known as serum sickness.

Safety and first aid:-

 Rattlesnakes are the leading cause of snakebite injuries in North America, and are a significant cause in Central and South America.

Avoiding bites:-

 

Rattlesnakes tend to avoid wide open spaces where they cannot hide from predators, and will generally avoid humans if they are aware of their approach.[60] Rattlesnakes rarely bite unless they feel threatened or provoked. A large majority of victims (~ 72%[61]) are males, often young and intoxicated. Approximately half of bites occur in cases where the victim saw the snake, yet made no effort to move away.[25]

Hikers and campers should avoid contact with rattlesnakes by remaining observant and not approaching the animals. Hikers are advised to be particularly careful when negotiating fallen logs or boulders and when near rocky outcroppings and ledges where rattlesnakes may be hiding or sunning themselves. However, snakes will occasionally sun themselves in the middle of a trail, so such areas are not the only places where they are encountered. When encountering a rattlesnake on a trail, hikers are advised to keep their distance and allow the snake room to retreat.[citation needed]

Caution is advised even when snakes are believed to be dead; rattlesnake heads can see, flick the tongue, and inflict poisonous bites for up to an hour after being severed from the body.

Effect of bites on humans
Rattlesnake bite injury:-

Rattlesnake bites are rarely fatal to humans, if treated promptly.[30] Between 7,000 and 8,000 people are estimated to have been bitten by venomous snakes in the United States each year, and about five of those die.[64] The most important factor in determining survival following a severe envenomation is the amount of time elapsed between the bite and treatment. Most deaths occur between 6 and 48 hours after the bite. However, if antivenom treatment is given within 1–2 hours of the bite, the probability of recovery is greater than 99%.[65]

When a bite occurs, the amount of venom injected is under voluntary control by the snake. The amount released is dependent on a variety of factors including the condition of the snake (e.g. having long, healthy fangs and a full venom sack) and its temperament (an angry, hungry snake that has just been stepped on vs. a satiated snake that was merely surprised by walking near it).[66] Approximately 20% of bites result in no envenomation at all. A lack of burning pain and edema 1 cm away from the fang marks after 1 hour, suggests that either no or minimal envenomation occurred. A lack of edema or erythema in the area of the bite after 6–8 hours indicates a lack of envenomation for most rattlesnake bites.[67]

Common symptoms include swelling, severe pain, weakness, anxiety, nausea and vomiting, hemorrhaging, perspiration, and heart failure.[66][68] Local pain following envenomation is often intense, increasing with the ensuing edema.[66] In general, children experience more severe symptoms because they receive a larger amount of venom per kilogram of body mass.

Emergency response:-

Data on the effectiveness of first aid techniques for rattlesnake bites is limited.[69] However, general recommendations for first aid in the field are as follows:

    Remain calm, and retreat from the snake at least 10–15 feet. Arrange to have the victim transported to a medical facility as soon as possible.[69]
    Remove restrictive clothing items (rings, bracelets, watches, buttoned shirts, etc.) from the victim.[69][70]
    Splint or otherwise immobilize any bitten limbs, and keep them below heart level.[30][34][69][71] If (and only if) the victim is more than 1–2 hours away from a medical facility, it is recommended to place a lightly constricting band (that admits one finger beneath it) above the bitten area to prevent the systemic spread of the venom.[69]
    Keep victims calm; put them at rest; keep them warm and give them comfort and reassurance (which will lower their heart rate, slowing the spread of the venom). However, keeping a victim's heart rate down should never interfere with getting him or her to a medical facility.[69]

In no case should tourniquets be used, nor should any incisions or suction be applied to the wound

Food

Journalist Alistair Cooke claims that rattlesnake tastes "just like chicken, only tougher."^[82] Others have compared the flavor to a wide range of other meats, including veal, frog, tortoise, quail, fish, rabbit, and even canned tuna.

Garter snake

The Garter snake is a Colubrid snake genus (Thamnophis) common across North America, ranging from Alaska and Canada to Central America. It is the single most widely distributed genus of reptile in North America[citation needed]. The garter snake is also the Massachusetts state reptile.[1]

There is no real consensus on the classification of species of Thamnophis. Disagreement among taxonomists and sources, such as field guides, over whether two types of snakes are separate species or subspecies of the same species is common. They are also closely related to the snakes of the genus Nerodia, and some species have been moved back and forth between genera.

Coast garter snake

Habitat

Garter snakes are widespread throughout North America. The common garter snake (Thamnophis sirtalis), is the only species of snake to be found in Alaska, and is one of the northernmost species of snake in the world, possibly second only to the Crossed Viper, Vipera berus. The genus is so far ranging due to its unparticular diet and adaptability to different biomes and landforms, with varying proximity to water. However, in the western part of North America, these snakes are more water loving than in the eastern portion. Northern populations hibernate in larger groups than southern ones.

Venom

Garters were long thought to be nonvenomous, but recent discoveries have revealed that they do in fact produce a mild neurotoxic venom.[3] Garter snakes cannot kill humans with the small amounts of venom they produce, which is comparatively mild, and they also lack an effective means of delivering it. They do have enlarged teeth in the back of their mouth, but their gums are significantly larger.[4][5] Whereas most venomous snakes have anterior or forward venom glands, the Duvernoy's gland of garters are posterior (to the rear) of the snake's eyes.[6] The mild venom is spread into wounds through a chewing action. The properties of the venom are not well known, but it appears to contain 3FTx, commonly known as three-finger toxin, which is a neurotoxin commonly found in the venom of colubrids and elapids. A bite may result in mild swelling and an itching sensation. There are no known cases of serious injury and extremely few with symptoms of envenomation.

Reproduction
Garter snakes go into brumation before they mate. They stop eating for about two weeks beforehand to clear their stomach of any food that would rot there otherwise. Garter snakes begin mating as soon as they emerge from brumation. During mating season, the males mate with several females. In chillier parts of their range, male common garter snakes awaken from brumation first, giving themselves enough time to prepare to mate with females when they finally appear. Males come out of their dens and, as soon as the females begin coming out, surround them. Female garter snakes produce a sex-specific pheromone that attracts male snakes in droves, sometimes leading to intense male-male competition and the formation of mating balls of up to 25 males per female. After copulation, a female leaves the den/mating area to find food and a place to give birth. Female garter snakes are able to store the male's sperm for years before fertilization. The young are incubated in the lower abdomen, at about the midpoint of the length of the mother's body. Garter snakes are ovoviviparous meaning they give birth to live young. However, this is different than being truly viviparous, which is seen in mammals. Gestation is two to three months in most species. As few as 3 or as many as 80 snakes are born in a single litter. The young are independent upon birth. On record, the greatest number of garter snakes to be born in a single litter is 98.

Diet

A Garter snake eating a frog

Garter snakes, like all snakes, are carnivorous. Their diet consists of almost any creature that they are capable of overpowering: slugs, earthworms, leeches, lizards, amphibians, birds, fish, toads and rodents. When living near the water, they will eat other aquatic animals. The ribbon snake (Thamnophis sauritus) in particular favors frogs (including tadpoles), readily eating them despite their strong chemical defenses. Food is swallowed whole. Garter snakes often adapt to eating whatever they can find, and whenever, because food can be scarce or abundant. Although they feed mostly upon live animals, they will sometimes eat eggs.
