The Olive Ridley turtles are the smallest and most abundant of all sea turtles found in the world.
Olive ridley gets its name from its olive colored carapace, which is heart-shaped and rounded.
They are carnivores, and feed mainly on jellyfish, shrimp, snails, crabs, molluscs and a variety of fish and their eggs.
They are found in warm waters of the Pacific, Atlantic and Indian oceans.
These turtles spend their entire lives in the ocean, and migrate thousands of kilometers between feeding and mating grounds in the course of a year.
They are best known for their unique mass nesting called Arribada, where thousands of females come together on the same beach to lay eggs.
Odisha’s Gahirmatha Marine Sanctuary is the world’s largest known rookery (breeding colony) of the olive Ridley sea turtles.
