Although mostly arboreal, this snake is also frequently found on the ground, and is active during both the day and night (2). It is highly prehensile, and will persistently grip any support within reach, with its tail or with its body. Its diet consists mainly of frogs and geckos, and occasionally skinks (2).
Unlike the majority of reptiles, the Palau bevelnosed boa gives birth to live young. Each litter contains an average of 12 young, but may contain as many as 50; litter size increases proportionally to the size of the female. Each female reproduces, on average, less frequently than once a year (5).
