Craspedocephalus borneensis, commonly known as the Bornean pit viper,[4] is a venomous pit viper species endemic to the island of Borneo.[1] No subspecies are currently recognized.[3][5]

Description

Scalation includes 19–21 rows of dorsal scales at midbody, 152–180 ventral scales, undivided anal scale, 45–58 divided subcaudal scales, and 8–11 supralabial scales.[4]

Its coloration varies. Individuals may be brown with darker brown saddles, or light brown with a few darker markings, or even bright yellow with darker markings.

Adults may attain 83 cm (33 in) in snout-vent length (SVL).[6]

Geographic range

Craspedocephalus borneensis is found on the island of Borneo (Brunei, Kalimantan, Sabah, Sarawak) as well as in the Natuna Islands.[1]

The type locality given is "Sarawack" (= Sarawak, Borneo).[2]

Habitat

It is found in forests below an altitude of 1,130 m (3,710 ft). Even though the tail is prehensile, adults are usually on the forest floor. Juveniles may be in low vegetation.[6]

Diet

Craspedocephalus borneensis preys upon small rodents and small birds.[1]

Reproduction

Whether this species of Craspedocephalus lays eggs or bears live young is as yet unknown.[6]
