Calamaria sangi

Calamaria sangi (Calamaria sangi) 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).

Calamaria reed snakes are small, cylindrical burrowers with compact heads and short tails, adapted to moving through soil, leaf litter and decaying vegetation. They are secretive and feed mainly on soft-bodied invertebrates such as earthworms, while many species are known from few specimens or localities. Fine scale characters are central to identification. These are genus-level notes rather than field observations of this Vietnamese record, so exact size, microhabitat, diet and clutch values are omitted (general Calamaria account; Reptile Database).
