Did you know...

Adult tree boas are green, but juvenile boas are born bright red

It is estimated that its population has been reduced by at least 20 percent in the past decade

This species of snake is endemic to the north and west of the Island of Madagascar where it is found in both the tropical rainforest and tropical dry forests.

It is a medium-sized constrictor growing to about 2 metres in length. They have heat sensitive pits around the mouth, which together with the tongue are used to locate its prey. It usually feeds on small mammals and birds.

Like most boas they are ovoviviparous, with the eggs developing and hatching inside the female. The 4-15 babies are born live after a development period of around six months.

Classified as vulnerable to extinction the Madagascar tree boa is threatened by habitat loss, mining operations and collection for the illegal trade in pets.
