Square-headed Cat Snake

Square-headed Cat Snake (Boiga kraepelini) is a snake recorded for Vietnam in the project inventory. Its supporting occurrence note is “Expert range list”. The accepted scientific name is retained because regional snake taxonomy and species boundaries can change, while similar-looking species may require scale counts, anatomy or genetic evidence for reliable separation. This profile therefore distinguishes the recorded identity and occurrence from broader biological context instead of inventing unsupported locality, size, diet or breeding details (project species data; Reptile Database taxonomy).

Boiga cat snakes are slender, mostly nocturnal and often arboreal colubrids with large eyes and vertically elliptical pupils. They search branches, shrubs and other cover for lizards, birds, frogs and small mammals, with diet varying among species. Boiga are rear-fanged and venomous, so handling is inappropriate even though effects differ by species. These are genus-level notes rather than Vietnam-specific observations of this record, and exact habitat, body size, prey and clutch figures are omitted (general Boiga account; Reptile Database).
