Overview

Blomberg's tree boa is a slender, non-venomous arboreal constrictor native to forested regions of western Ecuador and adjacent Colombia. It is one of the lesser-known members of the Corallus genus, with a comparatively restricted range along the Pacific slope of the Andes.

The species is named after Rolf Blomberg, a Swedish explorer and naturalist known for his work in Ecuador. It poses no venom risk to humans.

How to identify it

Blomberg's tree boa has the slender, laterally compressed body typical of arboreal Corallus species.

  • Coloration is generally tan, gray, or reddish-brown with darker, often faint blotching
  • Smooth scales and a strongly prehensile tail
  • Triangular head with heat-sensing labial pits, distinct from the neck
  • Adults typically reach 1.2-1.8 m (4-6 ft)
  • Slimmer, more subtly patterned appearance compared to the more vividly marked emerald tree boa

Habitat & range

This species inhabits humid forest along the Pacific lowlands and foothills of western Ecuador and adjacent Colombia. It is strongly arboreal, relying on forest canopy and dense vegetation.

Its relatively restricted range and forest dependency make habitat conservation important for the species' persistence.

Behavior, diet & reproduction

Blomberg's tree boa is nocturnal, hunting small mammals and birds from vegetation using ambush tactics and constriction, aided by heat-sensing pits to detect prey in darkness.

It is ovoviviparous, producing live young in modest litters typical of the genus. It tends to be secretive, and detailed behavioral data are less thoroughly documented than for more common relatives.
