We need to fully understand leatherback turtles to protect them.

A freediver and green sea turtle swam beside each other with their arms and flippers paddling in sync. Footage shows the swimmer gliding underwater with the friendly endangered marine creature in Cebu, the Philippines, on November 20. They floated upwards and were near the surface with sunlight shining through the water making a more mesmerising effect. Freediver Joy Parreno said: 'I started freediving only March last year. The underwater scenery is beautiful and the sea creatures are lovely.' Green sea turtles are large, herbivorous marine reptiles found in oceans worldwide. They are known for their distinctive greenish-coloured fat, which gives them their name. Although conservation efforts are present, it remains listed as Endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.

Costa Rica is Sea Turtle heaven. With 5 of the worlds 7 species choosing to nest here, it is important to keep its oceans and nesting beaches clean. Nesting turtles travel great distances (up to 2,000 miles) in between nesting seasons and then have to deter predators, crawl on to land, dig and lay eggs. Could you imagine delivering a baby in a plastic and garbage infested delivery room? So for the sake of one of the worlds most important creatures...please keep all our oceans and beaches clean. And if you want to see Sea Turtles in all their glory, come help with a beach cleanup in Costa Rica.

At least 32 people in the Philippines were admitted to hospital after consuming the endangered species.
