Olive Ridley

The Olive Ridley Sea turtle (Lepidochelys olivacea) is found existing in the warm waters of the Indian Ocean. It is relatively small in size with a black heart shaped upper exoskeleton that turns olive green in adulthood. It averages 60-70 centimeters in length, with a weight not exceeding 50kg. The Olive Ridley, known to be the sea turtle found most abundantly comes ashore in a unique phenomenon known as “arribada” where large groups of females come all at once to nest. The Olive Ridley feeds mainly on jellyfish, shrimp, mollusks and fish and has an average lifespan of 50 years.
