Annulated Tree Boa (Corallus annulatus)

The Annulated Tree Boa is a large arboreal species that inhabits the Caribbean side of Costa Rica. Unlike other Boa species like the Mesoamerican, one morph of this species are brownish-red in color, which renders them rather conspicuous against the dark green background in the tropical rain forest. Their nocturnal habits and preference for staying high in the trees make them difficult to spot. The color pattern consists of a series of diamond-shaped blotches, which are darker over the dorsum and lighter towards the venter. Some individuals have a cream base color instead of the brownish-red of the specimen shown below.
