Species overview
About the Annulated Tree Boa
The annulated tree boa is a forest snake with a broad head, a climbing body and a gripping tail. Dark-edged markings on a brownish background can resemble rings or linked shapes. Its colors suit the shadows of branches and foliage.
It is documented in Costa Rica’s Caribbean lowland wet forests. A resting tree boa can be difficult to detect even when it is not far away. Binoculars help you notice its posture while preserving space. A snake on a branch should have the same undisturbed escape route as one on the ground.

Habitat & range
Caribbean lowland wet forest and adjoining northern humid lowlands, including studied populations in northeastern Costa Rica.
Local observations
Native species recorded in Costa Rica. Sightings depend on suitable habitat and locality.
When to observe
Observe on a suitable guided outing. Activity varies with weather, season and locality; do not disturb a resting or hidden animal.
Conservation & care
Observe from a distance with an adult or qualified guide. Do not touch, catch, corner, feed or move any snake. Keep children and pets away. Colors, head shape and pupil shape must never be used to decide a snake is safe.
Threats & pressures
Protect connected habitat and natural shelters. Avoid collection, unnecessary clearing and deliberate killing. Leave wildlife in place and support responsible observation.
Observation activity
Find ringlike markings in the illustration. Explain how a repeating pattern can still help an animal hide.
