Common Mock Viper

Common Mock Viper (Psammodynastes pulverulentus) is a snake recorded for Vietnam in the project inventory. Its supporting occurrence note is “GBIF: 307 Vietnam records”. 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).

Psammodynastes mock vipers are small, cryptically coloured, rear-fanged snakes that hunt lizards, frogs and other small prey from ground cover or low vegetation. A triangular-looking head and defensive posture can resemble a viper, but identification requires scale and anatomical characters rather than appearance alone. Wild snakes should not be handled. These are genus-level notes rather than Vietnam-specific observations, so exact habitat, size, diet and reproductive figures are omitted (general Psammodynastes account; Reptile Database).
