Achalinus vanhoensis

Achalinus vanhoensis (Achalinus vanhoensis) 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).

Achalinus odd-scaled snakes are small, secretive forest-floor snakes with iridescent, overlapping scales and a dark, often subdued appearance. They burrow through moist soil, leaf litter and decaying wood, emerging infrequently and feeding on soft-bodied invertebrates such as earthworms. Their concealed habits and restricted localities leave many species poorly known. These are genus-level ecological notes rather than observations of this particular Vietnamese record, so exact habitat, size, diet and reproductive values are not inferred (general Achalinus account; Reptile Database).
