The Asiatic softshell turtle or black-rayed softshell turtle (Amyda cartilaginea)^[2] is a species of softshell turtle in the Trionychidae family. It is not the only softshell turtle in Asia (most trionychines are Asian).^[1]

Geographic range

It is found in Bangladesh (Bandarban region), Borneo, Brunei, Cambodia, northeastern India, Indonesia, Java, Kalimantan, Laos, Malaysia, Myanmar, Sabah, Sarawak, Singapore, Thailand, and Vietnam.^[3]

Description

Adults may attain a carapace length of 70 cm (27.5 in). The oval carapace has rounded sides, and the head is relatively narrow. This species exhibits sexual dimorphism in the color of the plastron, which is white in males, gray in females.^[3] A. cartilaginea is nocturnal.^[3]

Habitat

Amyda cartilaginea (Trionyx cartilagineus) in a Saint Petersburg museum

It prefers wetlands such as marshes, swamps, and large muddy rivers at lower elevations.^[3]

Diet

It preys on water insects, shrimps, fishes, and frogs.^[3]

Reproduction

Adult females lay eggs in holes on riverbanks. The spherical eggs are 21–33 mm (0.8-1.3 in) in diameter. The number of eggs laid in a clutch varies from four to eight.^[3]
