Ploughshare Tortoise Astrochelys yniphora

The Ploughshare Tortoise is also called the Angonoka Tortoise and the Madagascar angulated tortoise. It is related to the Radiated Tortoise (the only two in the genus) and has a high-domed carapace with black and gold markings.

The "Ploughshare" name is because its plastron has a forward-protuding finger like a ploughshare used for fighting among males, overturning rivals.

It is the rarest tortoise in the world, native to a single location in northwest Madagascar and critically endangered through illegal poaching. In addition, the introduced bushpig eats its eggs and young and illegal fires clear its remaining forest habitat.
