Turtles (order Testudines) are reptiles characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, a

Members of Testudines inhabit marine, brackish, and freshwater environments. Their temporal range begins in the Triassic period. The taxon is the source of tortoise shell.

Kura-kura dan penyu adalah hewan bersisik berkaki empat yang termasuk golongan reptil. Bangsa hewan yang disebut (ordo) Testudinata (atau Chelonians) ini khas dan mudah dikenali dengan adanya ‘rumah’ atau batok (bony shell) yang keras dan kaku. Batok kura-kura ini terdiri dari dua bagian. Bagian atas yang menutupi punggung disebut karapas (carapace) dan bagian bawah (ventral, perut) disebut plastron. Kemudian setiap bagiannya ini terdiri dari dua lapis. Lapis luar umumnya berupa sisik-sisik besar dan keras, dan tersusun seperti genting; sementara lapis bagian dalam berupa lempeng-lempeng tulang yang tersusun rapat seperti tempurung. Perkecualian terdapat pada kelompok labi-labi (Trionychoidea) dan jenis penyu belimbing, yang lapis luarnya tiada bersisik dan digantikan lapisan kulit di bagian luar tempurung tulangnya. Dalam bahasa Indonesia, kita mengenal tiga kelompok hewan yang termasuk bangsa ini, yalah penyu (bahasa Inggris: sea turtles), labi-labi atau bulus (freshwater turtles), dan kura-kura (tortoises). Dalam bahasa Inggris, dibedakan lagi antara kura-kura darat (land tortoises) dan kura-kura air tawar (freshwater tortoises atau terrapins).
