White Lipped Python(Leiopython)

Leiopython, formerly a monotypic genus, now comprises six species,[4] created for the non-venomous python species, L. albertisii, found in New Guinea. No subspecies are currently recognized.[5] It was first described as an intermediate genus between Liasis and Nardoa.[6] The species was named in honor of Luigi D'Albertis.


Description

Female Adults of the Northern White-Lipped Python (Leiopython albertisii) grow to an average of about 213 cm in length (6–7 ft), whereas the Southern White-Lipped Python (Leiopython hoserae) can reach up to 300 cm (10 ft) in length. They are patternless, except that the Northern White-Lipped Python has some light markings on their postoculars[3] absent in the Southern White-Lipped Python.[4] The snout is triangular and the head is distinct from the neck. The dorsum of the head is shiny black, the upper and lower labial scales are white with black markings on the anterior edge of the scales. Body color is either brownish-violet fading to yellowish ventrally (Leiopython albertisii) or blackish-blue fading to gray (Leiopython hoserae). These pythons also regurgitate fur balls, also known as "Casting." This behavior is rarely seen, but 2–3 days after feeding the results are seen. When it is witnessed owners of White lipped pythons often think their snake is regurgitating its food.


Geographic range

Found in most of New Guinea (below 1200 m), including the islands of Salawati and Biak, Normanby, Mussau and Emirau,[4] as well as a few islands in the Torres Strait. The type locality given is "Kapaor in Nova Guinea boreali occidentali ... et prope Andai..." also stated "... un esemplare a Kapaor fra i Papua Onin..." and "... un secondo esamplare ad Andai presso Dorei..." (Kapoar, Onin Peninsula and Andai, near Dorei, Irian Jaya, Indonesia).[1]

Some doubt can be cast on its occurrence on Normanby, as McDowell (1975)[8] had erroneously assigned Bara Bara to this Island, rather than to the mainland of Papua New Guinea[4] in Milne Bay Province as stated by Boulenger (1898)[9] and Koopman (1982).

Habitat

Associated with rain forests, cutover clearings and swamps. Usually found near water, into which they may quickly retreat if disturbed. Often hide under dead leaves on forest floor.[3]

Feeding

The diet includes a range of birds and mammals that are small to medium in size.[3] Neonates and young semi-adults often feed on lizards.

Reproduction
Oviparous, with females laying about a dozen eggs. The eggs stick together in a compact pile and the females coils around them. The hatchlings emerge after about two months of incubation and are about 38 cm (15 inches) in length.[3]
