Homalopsis buccata (puff-faced water snake or masked water snake) is a species of water snake in the Homalopsidae family found in tropical areas of Southeast Asia.
Description
Upper labials 1–4 contact single loreal; two prefrontals; 33–40 dorsal scale rows at mid-body, usually reduced to fewer than 30 posteriorly; one postocular plus a postsubocular; 12 (11–14) upper labials; ventral count fewer than 166. Homalopsis hardwickii has a divided loreal; H. nigroventralis has upper labials 1–3 contacting the loreal; H. semizonata has a divided or fragmented loreal contacting upper labials 1–4 or 1–5 and three prefrontals; H. mereljcoxi, has a single loreal contacting upper labials 1–4, scale rows at mid-body 40–47, reduced to 30 or more posteriorly. [1]
Distribution
Homalopsis buccata ranges from northern Sumatra to Salanga Island, Indonesia and Borneo; it is present on the Malaysian peninsula and in extreme southern Thailand (vicinity of Pattani). [2]
Reproduction
Homalopsis buccata are ovoviviparous, meaning they do not lay eggs, but rather give birth to live young. Female Homalopsis give birth to 2-20 live young, with an average of 9.26 young per breeding. Studies have not shown this species breeds year round, with a peak season of October-March, though no distinctive breeding season was found, with young being born throughout the year. [3]
Diet
Prey items are said to include: Tilapia, Guppies (Lebistes), Catfish (Mystus) Asian Swamp Eels (Fluta alba), various other small fish Fish, a variety of frogs, freshwater crustaceans. [4]
In captivity, the species feeds readily on minnows, goldfish, various cichlid fish, Tilapia, Mollies (Poecilia), and tadpoles.
