Dipsadoboa aulica, commonly known as the marbled tree snake, is a species of snake in the family Colubridae. The species is endemic to Africa, and is mildly venomous to humans.

Geographic range

D. aulica is found in Eswatini, Malawi, Mozambique, Somalia, South Africa, Tanzania, and Zimbabwe.

D. aulica is a slender-bodied snake. Males may attain a snout-to-vent length (SVL) of 66 cm (26 in). Females are slightly smaller, growing to 63 cm (25 in) SVL. The smooth dorsal scales are arranged in 17 rows at midbody.

Behavior

D. aulicus, is nocturnal and arboreal, hiding during the day in tree cavities or under bark.

Diet
