The nesting population of this marine turtle in the Peninsular is very small. A low number of nests is recorded annually in Terengganu, Pahang, Perak, Penang, Sabah and Sarawak. [2]
The olive ridley turtle is the smallest among the marine turtles. It weighs between 30-50 kg. Its carapace length is only 50-70cm. The carapace is made up of 5-9 pairs of costal scutes. Underneath, the margins are smooth with pores between inframarginal scutes. [3]

The carapace is dark olive green in color with a yellowish underside. [1] The head is relatively large compared with green and hawksbill. Male olive ridley has a long tail with heavy terminal nail. [5]
Olive Ridley is a carnivore, feeding mainly on shrimps, jellyfish, crabs and snails. [2] These turtles forage offshore in surface waters and can dive to depths of at least 150 meters (500 feet). [1]

The nesting season in Perak is from January to December (peak season: April-June). On the island of Penang, nesting occurs from August to February (peak season: November-December) and on the east coast of the Peninsular, nesting occurs from January to September (peak season: March-May). [2]
