Varanus Bitatawa yang terancam punah

Varanus Bitatawa, namanya kurang akrab di telinga kita, Spesies varanus atau biawak yang baru terdokumentasi resmi di the Royal Society Biology Letters. Biawak besar yang hidup di hutan Sierra Madre di Luzon Island di utara Filipina ini, Banyak diburu oleh warga lokal filipina untuk dimakan. karena katanya kandungan protein yang baik, dan rasanya seperti daging ayam, padahal banyak orang di seluruh dunia yg tertarik dengan keberadaan spesies biawak ini.

Filipina memang terkenal memiliki keragaman spesies biawak, namun jenis Varanus Bitatawa baru sekarang ini muncul ke permukaan. Hutan Filipina yang belum banyak terjamah tangan manusia menyimpan misteri keberagaman spesies reptil di dalamnya, karena ulah manusia yg menebang pohon yang akhirnya mengurangi tempat hidup dari spesies ini, mau tidak mau spesies yang ada didalamnya mulai terekspos. Jenis Varanus Bitatawa ini cenderung menetap di hutan Sierra Madre, dan jarang terekspos manusia.

Yang Menarik, Spesies varanus Bitatawa memiliki Kebiasaan unik, Varanus Bitatawa memiliki kerabat dekat dengan Varanus Olivaceus yang juga dari Filipina. ditandai dengan kebiasaannya memakan buah walaupun mereka tetap mau memakan serangga dan mamalia lainnya. Apa jadinya bila Varanus olivaceus dan Varanus Bitatawa di silangkan, mungkin akan menjadi spesies baru yang sangat menarik..


karena jumlahnya yg di perkirakan sangat sedikit di alamnya, kini usaha untuk melestarikan Spesies ini di Filipina tengah digalakkan. ada yang tertarik untuk melestarikannya di rumah Anda? hehehe

Leiopython

From Wikipedia, the free encyclopedia

Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Reptilia
Order: Squamata
Suborder: Serpentes
Family: Pythonidae
Genus: Leiopython
Hubrecht, 1879


Common names: white-lipped python, D'Albertis' python, D'Albert's water python.

Leiopython, formerly a monotypic genus, now comprises six species, created for the non-venomous python species, L. albertisii, found in New Guinea. No subspecies are currently recognized. It was first described as an intermediate genus between Liasis and Nardoa. 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 absent in the Southern White-Lipped Python. 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 it's food.

Geographic range

Found in most of New Guinea (below 1200 m), including the islands of Salawati and Biak, Normanby, Mussau and Emirau, 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).

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

Feeding

The diet includes a range of birds and mammals that are small to medium in size. 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.

Taxonomy

A new species L. hoserae, and two new subspecies L. albertisii barkeri and L. a. bennetti, were described in Hoser (2000), but these descriptions are considered vague and questionable. In 2008, Schleip redescribed and provided proper descriptions and diagnoses for two of Hoser's (2000) taxa, Leiopython hoserae, from the southern lowlands of Papua New Guinea and neighbouring Indonesia, and L. benettorum, from the highlands of Morobe Province, Papua New Guinea. A third, Leiopython albertisii barkeri was considered a nomen nudum due to Hoser not having provided a description that includes characters to differentiate this taxon from others. Three new species were also described: L. biakensis from the island of Biak (part of the Indonesian Province of Papua, L. fredparkeri from the Karimui Basin, Simbu Province, Papua New Guinea, and L. huonensis from the Huon Peninsula, Morobe Province, Papua New Guinea.

The taxonomy of the Pythonidae family is fluid, however, an arrangement of the genus may be summarised as:

Pythonidae
