Species Profile

Species Aplopeltura boa
Common Name Blunt-headed Tree Snake
Family Pareatidae
Order Squamata
Distribution Malaysia (including Penang as well as Peninsular Malaysia, Sarawak and Sabah), Indonesia, Brunei Darussalam, the Philipines, and southern Thailand.
Habitat Low vegetation of lowland and montane forest of up to 1300m elevation.
Description  Nocturnal and arboreal, the Blunt-headed Tree Snake is the only species of its genus. It can measure up to a maximum length of 80 cm. The body is slender and flattened on both sides with a wide head and eyes that measure more in diameter than the length of its snout. Coloration varies from light to dark greyish brown, with dark-edged saddles on the back. The lip is usually white with a dark triangular area below the eye.
Notes  The Blunt-headed Tree Snake is a snail-eating specialist. Since snails are predominantly dextral (clockwise) with a right-sided opening, this snake has developed asymmetrical teeth arrangement. It has more needle-like teeth on the right mandible than the left and a hook-like jaw to efficiently extract its prey from its shell.
Conservation Status  Least Concern
