How to Identify Blomberg's Tree Boa (Identification Guide)

Key identifying features

Blomberg's Tree Boa is a member of the Corallus tree boa group native to a limited range in western Ecuador and Colombia. It shows the classic tree boa traits of a laterally compressed body, a large arrow-shaped head, and prominent heat-sensing pits along the lips for detecting warm-blooded prey.

Coloration & pattern

Coloration typically ranges from tan, gray, or brown to occasionally reddish tones, marked with darker irregular blotches or saddle-shaped markings running along the back. Pattern contrast can vary from bold to relatively subdued between individuals, so overall body proportions and head shape are more consistent identification cues than color alone.

Head, eyes & scales

The head is large, broad, and triangular, clearly distinct from a narrow neck. Deep heat-sensing pits line the upper and lower lip scales, allowing the snake to detect warm-blooded prey in darkness. The eyes are large with vertical pupils, suited to its nocturnal habits. Body scales are smooth.

Size & body shape

Adults typically reach around 4 to 6 feet, a moderate size for the group, with a body that retains the characteristic lateral compression of tree boas, taller than it is wide. The tail is strongly prehensile for anchoring on branches.

Range & habitat where you'll see it

This species inhabits humid tropical forest in parts of western Ecuador and Colombia, occupying similar arboreal niches to other tree boas, typically resting on branches or in dense vegetation during the day and hunting actively at night.

How to tell it apart from look-alikes

Its restricted range in western Ecuador and Colombia is a useful distinguishing clue, since it does not broadly overlap with most other Corallus tree boas. As with related tree boas, the presence of visible heat-sensing pits and a strongly compressed, deep body separate it from unrelated arboreal snakes lacking these specialized features.
