Asian box turtles are turtles of the genus Cuora in the family Geoemydidae. About 12 extant species are recognized.[1] The keeled box turtle (Pyxidea mouhotii syn. Cuora mouhotii) is often included in this genus, or separated in the monotypic genus Pyxidea. Genus Cuora is distributed from China to Indonesia and the Philippines, throughout mainland Southeast Asia, and into northern India and Bhutan.[1]

Description

Cuora species are characterized by a low- (e.g.

shell, which usually has three keels on the carapace
. They are reddish, yellowish, brown, grey, and/or black in color. Some species have bright yellow, black, orange, or white stripes down the length of their keels. Their body color is highly variable, but usually very intense. Most species show stripes of variable color down either side of their heads, which usually meet at the nose.

Background

Asian box turtles are the most heavily trafficked turtles in the world. They are captured and sold as food to China, and to the

Trafficking in turtles is a major issue in Southeast Asia, and it's important that we understand the key ecological roles that species like this box turtle play before it's too late,"[2]

Different conservation organizations are taking action to prevent or slow down the extinction of these species, but in the past, most of the efforts failed due to lack of biological research regarding the history or genetic diversity of these species.[3]

Behavior

Asian box turtles are terrestrial, semiaquatic, or mainly aquatic, most spending much of their time on the edge of shallow swamps, streams, or ponds that are dense with vegetation. Most are

carnivores

Taxonomy and systematics

Listed alphabetically by binomial name, the species are:[4]

turtle farm is known to produce C. serrata-like specimens.[14]
The occurrence of wild hybrids is often regarded as "evolution in progress", a terminology and point of view that is not always accepted. It has yet to be confirmed, whether all C. serrata from the wild have originated by direct hybridization of C. mouhotii and C. galbinifrons, or also by "hybridisation" of C. serrata × C. serrata.

Unnamed hybrids of several other Cuora

Mauremys mutica, which is intentionally produced in Chinese turtle farms.[12]

In captivity

Wild-caught C. amboinensis specimens were frequently available in the exotic animal trade, but are getting rarer now; other species are rare to commercially extinct.
