The Red-eared Terrapin (Trachemys scripta elegans) is a widely introduced species that can be found in a range of aquatic habitats throughout Southeast Asia, such as temple ponds, ornamental lakes and reservoirs. It originates from the southern Unites States, and is widely available in the international pet trade.

The carapace of juveniles are bright green, and this darkens with age. There are pale yellow stripes on top and on the sides of the head, and red markings behind the ear.

During the day groups of these terrapins may be seen sunning themselves on rocks or fallen logs.

In Singapore this terrapin is widespread: juveniles are typically released once they have grown too large to keep or have lost their attractive colours.

There appears to be little evidence that this species has successfully bred in the wild in Singapore: egg-laying behaviour has been witnessed, but hatchlings are rarely seen. It may be the case that eggs and hatchlings fall prey to predators, such as the Malayan Water Monitor.
