The Reptiles Of Madagascar

Madagascar’s wildlife composition is an indication that the island has existed in isolation for over 85 million years. The country is estimated to have split from India about 88 years ago leading to plants and animals on the island evolving in isolation. Thus, Madagascar is home to unique plants and animals that cannot be found anywhere else in the world. Most of the plants and animals found on the Island of Madagascar are endemic including birds, amphibians, mammals and reptiles. The reptiles of Madagascar comprise of a number of species of crocodiles, chameleon, tortoise, and ferocious predators. These predators include;

Malagasy Ground Boa

Malagasy Ground Boa, scientifically called Acrantophis madagascariensis and a member of the Boidae family, is a species of snake endemic to the Island of Madagascar. Boa is the longest snake in Madagascar with the adult female measuring up to 10 feet while the male measures 8 feet in length. The snake has diamond-like marks on its back with pale reddish-brown to gray color patterns. The male Boa has vestigial hind limbs or claws, differentiating it from the female. Malagasy Ground Boa lives in sparse open woodlands of Madagascar and takes shelter in debris, barrows, and fallen trees. The female can copulate with more than one male and gives birth to 4-5 young ones. The snake hunts by coiling around its prey and suffocates it to death then swallows it whole. The threats facing Malagasy Ground Boa include deforestation, illegal pet trade, and human population growth.

Radiated Tortoise

The tortoise has a life span of up to 188 years and is classified as Critically Endangered by the IUCN due to the major destruction of its habitat.
