Rhinoceros snake, Rhino rat snake, Vietnamese longnose snake
The rhinoceros ratsnake (Gonyosoma boulengeri), also commonly known as the rhinoceros snake, rhino rat snake, and Vietnamese longnose snake, is a species of nonvenomous ratsnake in the family Colubridae. The species is found from northern Vietnam to southern China. It has a prominent, distinctive, scaled protrusion on the front of its snout, which has led to its common naming after a rhinoceros.
The specific name, boulengeri, is in honor of Belgian-British biologist George Albert Boulenger.
The adult size of G. boulengeri is 100–160 cm (39–63 in) in total length (including tail). Its scale count includes 19 rows of dorsals at midbody.
