The Cuban Boa, which can grow to up to 6 metres in length, is one of the largest boas in existence. Its diet is carnivorous and when they hunt they constrict their prey until asphyxiation.
They are viviparous, in other words, the egg develops inside the female and the babies are born fully developed (6-28 babies) with some 40cm in length. The eggs develop covered in a membrane.
Cuban boas are animals in danger of extinction. They can be found in holes, rocks and croplands, although they were originally tree-dwelling.
