Ahaetulla fusca

Ahaetulla fusca (Ahaetulla fusca) 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).

Ahaetulla vine snakes are slender, arboreal colubrids with elongated heads and excellent vision. They move slowly through shrubs and trees, relying on camouflage before striking lizards, frogs and other small vertebrate prey. Members are rear-fanged and mildly venomous, so they should be observed without handling. Colour and head shape vary among closely related species. These are genus-level notes rather than field observations from Vietnam, and exact size, habitat, diet and reproductive figures are omitted (general Ahaetulla account; Reptile Database).
