Homalopsinae
The Homalopsidae are a family of snakes which contains about 28 genera and more than 50 species. They are commonly known as Indo-Australian water snakes, mudsnakes, or bockadams. They are also known as ''ular air'' (lit. "water snake") in Indonesian. They are typically stout-bodied water snakes, and all are mildly venomous. Two monotypic genera are notable for their unusual morphology: '' Erpeton'' possesses a pair of short, fleshy appendages protruding from the front of the snout, and '' Bitia'' has uniquely enlarged palatine teeth. ''Cerberus'' species have been noted to use sidewinding to cross slick mud flats during low tide. '' Fordonia'' and '' Gerarda'' are the only snakes known to tear their prey apart before eating it, pulling soft-shelled crabs through their coils to rip them apart prior to ingestion.

Bitia teeth of the upper jaw being smaller. In ''Bitia hydroides'', the palatine teeth are greatly enlarged. Not enough is known about this animal's feeding behavior or ecology to attempt to infer a function of this peculiar arrangement.
The keel-bellied water snake (''Bitia hydroides'') is a marine homalopsine snake. It belongs to the monotypic genus ''Bitia''. Geographic range It is found in Malaysia. Dentition ''Bitia hydroides'' is noted for its unusual dentition. In all other snakes, any enlarged teeth are located on the dentary or maxilla, with the inner, palatine A palatine or palatinus (in Latin; plural ''palatini''; cf. derivative spellings below) is a high-level official attached to imperial or royal courts in Europe since Roman times.

New Guinea Bockadam
''Cerberus rynchops'', also known as the New Guinea bockadam, South Asian bockadam, bockadam snake, or dog-faced water snake, is a mildly venomous species of a snake in the family Homalopsidae. It is native to coastal waters of South and Southeast Asia. The species was re-delimited in 2012, allocating populations east and south of the west coast of Thailand to other species. Ecology and behaviour It is commonly found in mangrove A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in severa ...s, mudflats, streams, ponds, tidal pools, on algae patches, and has even been found burrowing into the mud. It is rear-fanged and is mildly venomous. An aquatic and nocturnal snake, it feeds mainly on fish and is known to consume eels.

Sidewinding
Sidewinding is a type of locomotion unique to snakes, used to move across loose or slippery substrates. It is most often used by the Saharan horned viper, '' Cerastes cerastes'', the Mojave sidewinder rattlesnake, '' Crotalus cerastes'', and the Namib desert sidewinding adder, '' Bitis peringueyi'', to move across loose desert sands, and also by Homalopsine snakes in Southeast Asia to move across tidal mud flats. Any number of caenophidian snakes can be induced to sidewind on smooth surfaces, though the difficulty in getting them to do so and their proficiency at it vary greatly. The method of movement is derived from lateral undulation, and is very similar, in spite of appearances. A picture of a snake performing lateral undulation would show something like a sine wave, with straight segments of the body having either a positive or negative slope. Sidewinding is accomplished by undulating vertically as well as laterally, with the head tracing out an ellipse in a vertical pl ...

Homalopsis
''Homalopsis'' is a genus of snakes of the Family (biology), family Homalopsidae. The genus is restricted to South East Asia and includes five currently recognized species. Like all members of the family Homalopsidae, ''Homalopsis'' are rear-fanged and mildly venomous, though considered harmless to humans. Habitat ''Homalopsis'' are a freshwater aquatic species that are found in a wide range of habitats including ponds, rivers, flowing streams, swamps, marshes and other wetlands. Human disturbance and activity does not seem to hinder this species as much as others and can be actively found in disturbed habitat such as man-made drainage ditches and irrigated agriculture fields.Murphy, John C. 2007. Homalopsid Snakes: Evolution in the Mud. Krieger Publishing, Malabar, Florida, 249 pp. Behavior This species is nocturnal and can be found in muddy bank holes or burrows during the day. It feeds primarily on fish but may also eat anurans and possibly crustaceans. Reproduction ''Homal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dieurostus
''Dieurostus'' is a genus of snake in the family Homalopsidae. The genus ''Dieurostus'' is monotypic, containing only the species ''Dieurostus dussumieri'', commonly known as Dussumier's water snake, or the Kerala mud snake. The species, which is mildly venomous and rear-fanged, is endemic to Kerala, in southwestern India. It was formerly thought to be found in Bangladesh, although its distribution there is now disputed. Etymology Both the specific name, ''dussumieri'', and the common name, Dussumier's water snake, are in honor of Jean-Jacques Dussumier, a French merchant, ship owner, and collector of zoological specimens.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Enhydris dussumierii'', p. 78). Morphology Diagnosis (genus): ''Dieurostus'' is distinguished from all other homalopsids with 25 or 27 rows of smooth scales, nasal scales in contact, and posterior labia ...

Fordonia
''Fordonia leucobalia'' is an aquatic snake known by the common names crab-eating water snake and white-bellied mangrove snake. It is a common resident of mangrove swamps and tropical tidal wetlands from coast of Southeast Asia to Indonesia and the coasts of Northern Australia The unofficial geographic term Northern Australia includes those parts of Queensland and Western Australia north of latitude 26° and all of the Northern Territory. Those local government areas of Western Australia and Queensland that lie p .... Individual ''F. leucobalia'' reach up to a meter in length, and are brown or gray in color with a white belly. There is significant color variation. Some have spots. The anatomy reflects the snake's water-living lifestyle: the eyes are located atop the head, and the nostrils have valves that close when the snake dives. The snake eats small prey that live in its habitat, such as frogs and small fish, and it specializes in crabs, hence its name. Like other ...

Erpeton
The tentacled snake or tentacle snake (''Erpeton tentaculatum'') is a rear-fanged aquatic snake native to Southeast Asia. It is the only species of the genus ''Erpeton''. The two tentacles on its snout are a unique feature among snakes. Description The tentacled snake is a relatively small snake, averaging about in length. They are known to come in two color phases, striped or blotched, with both phases ranging from dark gray or brown to a light tan. It lives its entire life in murky water. The tentacled snake is the only species of snake to possess twin "tentacles" on the front of its head, which have been shown to have mechanosensory function. Its diet consists solely of fish. Although it does have venomous fangs, the tentacled snake is not considered dangerous to humans. The fangs are small, only partially grooved, and positioned deep in the rear of the mouth. The venom is specific to the fish that the tentacled snake eats. Distribution A native of Southeast Asia, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myanophis
''Myanophis'' is a genus of snake in the family Homalopsidae that contains the sole species ''Myanophis thanlyinensis''. It is endemic to Myanmar, and was described in 2021 from two male and two female specimens found in the vicinity of the campus of East Yangon University. Aside from genetic differences, it can be distinguished from all other homalopsid genera by its smooth dorsal scales, short tail length in relation to the body, separated nasal scales, unique number of ventral and subcaudal scales, and bilobed hemipenis A hemipenis (plural hemipenes) is one of a pair of intromittent organs of male squamates (snakes, lizards and worm lizards). Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like ... in males. It is most closely related to the genera '' Myrrophis'' and '' Gyiophis'', from which it can be distinguished by its bilobed hemipenis as opposed to unilobed in the other two genera. References ...
