Madagascar Tree Boa

The Madagascar tree boa, or Malagasy tree boa, as the name suggests, is endemic to Madagascar. The constrictor is usually nocturnal and arboreal. It has heat-sensing pits that help it forage warm-blooded prey in the dark. Despite its medium size, it is a mighty snake with strong jaws.

Color and Appearance

The greenish background color of the boa is overlayed with darker markings, often with lighter centers. A dark stripe extends diagonally from its eye towards the back of its head. Its smooth glossy scales are neither ridged nor keeled, and its pupils are elliptical.

Are They Dangerous to Humans 

The Madagascar tree boa is not aggressive. The shy snake tries to stay out of people’s way when hunting for food. If cornered, it can bite but can’t cause any harm as it is non-venomous.

As pets, they are docile and fairly easy to handle.

Madagascar Tree Boa Habitat

It lives in the eastern part of Madagascar.


It prefers shrubs and trees near rivers, streams, swamps, and ponds.


Malagasy tree boas live for up to 30 years.


They are eaten by the fossa, larger snakes, and birds of prey.


Its diet consists of birds and mammals that it forages using thermoreceptive pits located between its labial scales. The boa’s razor-sharp teeth help it hold on to the prey as it kills it by constriction. It leaves trees to hunt small mammals on the ground.


Ovoviviparous (gives birth to live young from eggs that hatch inside the body)

Juveniles Madagascar Tree Boa

When females become gravid, their skins darken in color, increasing heat absorption for nurturing the young. After giving birth, their color returns to normal at their next molting. The juveniles are bright red, possibly to warn predators to stay away from them and help them camouflage among the bright flowers on tree tops.
