What to know about olive ridley turtles
A clean field guide focused on habitat, identification, behavior, and conservation context without burying the useful parts.
The olive ridley sea turtle (Lepidochelys olivacea) is a species in the family Cheloniidae. It is the second-smallest and the most abundant of all sea turtles. Olive ridleys occur in warm and tropical waters, primarily in the Pacific and Indian Oceans, and also in warm areas of the Atlantic Ocean. This species and the related Kemp's ridley are known for synchronized mass nestings called arribadas, when thousands of females come together on the same beach to lay eggs.
The strongest linked planning options currently surface around destinations such as Bahias de Huatulco, Bonaire, Grenada (St. George's and Grand Anse) and countries such as Mexico, Costa Rica, Ecuador for divers building trips around olive ridley turtles.
