About the Blunthead Tree Snake

Imantodes cenchoa, also known commonly as the blunthead tree snake, the neotropical blunt-headed tree snake, and the fiddle-string snake, is a species of mildly venomous, rear-fanged snake in the family Colubridae. The species is native to Mexico, Central America, and South America.

The blunthead tree snake averages about 800 mm (31 in) in total length (including tail). Maximum total length is about 1.5 m (4 ft 11 in). I. cenchoa is known for its long, slender body and very large head. The pupil of its eye is very distinct from other snakes. Most snakes found around the world are known to have very poor vision and rely mostly on smell and vibrations to detect signs of prey and predators. Arboreal snakes have much better vision than other snakes. The blunthead tree snake has a vertical slit for a pupil which allows the snake to look downward. This trait gives the blunthead tree snake an advantage over other snakes. The large eyes make up approximately 26% of its head.

The ventral surface, or stomach, of the blunthead tree snake is mostly white, while the dorsal surface, or top, is a light or pale brown with lateral dark brown patches that begin at the head and continue... Wikipedia →
