Maximum Carapace Length : 28 cm

Originating from the U.S., the Red-eared Terrapin has been introduced into many waterbodies in Southeast Asia, particularly in temple ponds, public parks and reservoirs. Such releases are either bored pet owners who want to rid themselves of their terrapins, or are Buddhists making 'merit'.

The shells of juveniles are bright green, and this darkens with age. The face shows a distinctive arrangement of pale yellow stripes, and red markings behind the ear.

During the day groups of these terrapins can be seen sunning themselves on rocks or fallen logs. The species is well established around urban areas, and is likely to spread to other habitats in future; there is a danger that these will displace native species.
