10Galapagos Islands, Ecuador

The Galapagos green sea turtle (Chelonia mydas agassisi) is a subspecies of green turtle that can only be found nesting in the archipelago of the Galapagos. This subspecies inhabits the subtropical and tropical waters of the Pacific Ocean, and it can be distinguished from other green sea turtles by its serrated lower jaw and the single pair of scales covering its eyes. 

These turtles can be seen while snorkeling and diving in the Galapagos all year long. The principle nesting site is Quinta Playa on Isabela Island. Best time: December to March
