Scientific name: Lepidochelys olivacea

Stock Assessment / Estimated Breeding Population

While many of the nesting populations along the Pacific coast of Mexico have disappeared, an estimated 450,000 turtles still nest in arribadas at La Escobilla. Costa Rica supports an estimated 600,000 nesting olive ridleys between its two major arribada beaches Nancinte and Ostional. Other countries in the Pacific hosting nesting populations producing between 100 and 2,000 nests per year include Guatemala, Honduras, El Salvador, Australia, Brunei, Malaysia, Indonesia, and Vietnam.
