Boiga ceylonensis (Sri Lanka cat snake) is a species of rear-fanged, mildly venomous, nocturnal, arboreal colubrid snake endemic to Sri Lanka.[2]
Description
[edit]This is a thin-bodied, elongate, slim, tree snake. Taxonomic features: Dorsal Scales in 19 rows, oblique ; scales along the vertebral row much enlarged, and at mid body nearly as broad as long. Ventrals scales 217–237; the anals are undivided, subcaudals 95–109. The colour is brown or greyish above, with a series of blackish transverse cross bands ; nape with a blackish blotch, or three blackish longitudinal streaks, or a transverse bar ; a more or less distinct brown crown marking on top of head and a thick streak from the eye to the angle of the mouth ; lower parts yellowish, dotted with brown, usually with a lateral series of small brown dots. They are about 4 feet long from tip to tip with the tail 10 inches.
Distribution range
[edit]It is an endemic species to Sri Lanka. Previously believed to occur in the Western Ghats of India, but was falsified by recent studies.
Interaction with humans
[edit]This snake frequently ventures into human dwellings in search of prey such as geckos. It has a somewhat aggressive disposition and boldly strikes out when disturbed or cornered.[3] This snake is known as Nidi mapila by the Sinhala speaking community of Sri Lanka.[4]
