Ploughshare tortoise  (Astrochelys yniphora)

This species is one of the rarest land tortoises in the world (4). Its common name refers to the appearance of the 'gular scute' (5) at the lower part of the shell (plastron), which is drawn out into a plough-shaped projection between the front legs (6). The upper shell (carapace) is hard, highly domed and brown in colour, with prominent concentric growth rings on each scute (5). Males are larger than females (2).
