''Geochelone'' is a genus of tortoises. ''Geochelone'' tortoises, which are also known as typical tortoises or terrestrial turtles, can be found in Africa and Asia. They primarily eat plants. The genus consists of three extant species: *Indian star tortoise (''G. elegans'') *Burmese star tortoise (''G. platynota'') *African spurred tortoise (''G. sulcata'') A number of tortoise species have been recently removed from the genus. This taxon as formerly defined was "polyphyletic, representing at least four independent clades". Tortoises removed include members of ''Aldabrachelys'' (from the Seychelles and Madagascar), ''Astrochelys''〔 (Madagascar), ''Chelonoidis'' (South America and the Galápagos Islands), ''Stigmochelys'' (Africa) and earlier, the extinct genus ''Colossochelys'' (southern Asia). =="Self-righting" shell== The form of the shell of the Indian star tortoise resembles a ''gömböc'', allowing it to turn over when lying upside down very easily. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geochelone」の詳細全文を読む スポンサード リンク
