Deinagkistrodon acutus

Deinagkistrodon acutus (Deinagkistrodon acutus) is a snake recorded for Vietnam in the project inventory. Its supporting occurrence note is “GBIF: 6 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).

Deinagkistrodon is a terrestrial pit-viper lineage recognized by its broad triangular head and strongly patterned, heavy body. It is an ambush predator of small vertebrates and uses facial heat-sensing pits when locating warm-bodied prey. Its venom is medically significant, making close approach or handling unsafe. This paragraph gives general biological context only, not field observations from Vietnam; precise habitat, size, prey composition and reproductive values are omitted rather than transferred without a species-level local source (general Deinagkistrodon account; Reptile Database).
