The Madagascan Big-Headed turtle (Erymnochelys madagascariensis) is a turtle native to the waters of permanent slow moving rivers and lakes in western Madagascar. These turtles, although they are critically endangered (the 13th most endangered turtle, according to the top 25 most endangered turtles list, they are commonly eaten for food but they are still commonly shipped from Madagascar to Asia to help meet the demand of Asia's traditional medicine market.
A captive breeding program has also been started to prevent the species from becoming extinct. The Madagascan big-headed turtle is one of the most endangered turtles in the world, and is also included in the Turtle Conservation Funds (TFC) top 25 endangered.
It has a hard dark brown shell enclosing all the soft parts of the body and as its name says it, a really large head. Young turtles have a soft pattern of fine black lines on their shells, but they disappear with age.
The main threat for this species is that they heavily exploited for food, caught in nets, fish traps and by hooks and lines. It is also hunted for illegal export to Asia for the traditional medicinal market. Another threat is the land development as it destroys its natural habitat.
