Biology

Live in mesic forests such as lowland rainforests and wet mountain forests. Moderately slender to stout snakes. Posterior part of the head particularly broad. Snout pointed or round. In some the snout is turned upwards (mainly B. hyoprora).
Tail not prehensile. Basic colouring in varying shades of brown to black. A series of broad dark cross bands. Special element of the pattern is a series of yellow, white or pale blue-grey spots or bars on the infralabials. All species are distinctively stout-bodied and large-headed snakes, most easily confused with Boas.

Risk

B. hyoprora and B. microphthalmus bites seem to be potentially severe. A bite from a juvenile B. colombianus was reported to be severe (Ayerbe 2000, 2001).
