Out of 7 sea turtles in the world, five of it can be found in the Philippines – the critically endangered hawksbill, the endangered green turtle, and olive ridley, loggerhead, and leatherback as vulnerable. Unlike its freshwater cousins, sea turtles cannot retract their head, legs, and arms into their shell for protection but this body structure makes swimming easy. And because they have lungs and breathe air, they need to surface for air at regular intervals. Places to visit for turtles sighting include Apo Island, Apo Reef, Helicopter Island (El Nido), Pescador Island (Cebu), Balicasag Island, and Mantigue Island (Camiguin).

Giant clams are called taklobo in the Philippines
