Wagler's Pit Viper

Wagler's Pit Viper (Tropidolaemus wagleri) 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).

Tropidolaemus are heavy-bodied arboreal pit vipers that spend long periods coiled on branches, relying on camouflage and ambush rather than active pursuit. Facial heat-sensing pits assist in detecting warm-bodied prey, and the strongly contrasting colours of adults can vary by sex and age. The snakes are venomous and should not be handled. These are genus-level notes rather than a Vietnam-specific account of this record, so exact measurements, diet and breeding details are omitted (general Tropidolaemus account; Reptile Database).
