Speke's hinge-back tortoise : ウィキペディア英語版 | Speke's hinge-back tortoise
The Speke's hinge-back tortoise (''Kinixys spekii''), is a species of turtle in the Testudinidae family. It is found in Africa. ==Description== This tortoise has an elongated carapace, up to 20 cm in length, which is distinctly flattened (allowing it to seek refuge in rock crevices and under logs). Its carapace has a weak, disrupted medial keel, and posterior marginals that are neither strongly serrated nor reverted. This species has a well-developed hinge at the rear end of the upper part of its shell, permitting the protection of its rear legs after they have been retracted.〔(nlbif.eti.uva.nl )〕 The male has a notably longer tail than the female of this species, and the tails end in a spine. Females possess a flat plastron, yet males have a more concave one.〔(Chelonia.org )〕
