Baku, October 15, AZERTAC Located 550 km off the Pacific coast of Costa Rica, Cocos Island National Park is the only island in the tropical eastern Pacific with a tropical rainforest.Its position as the first point of contact with the northern equatorial counter-current, and the myriad interactions between the island and the surrounding marine ecosystem, make the area an ideal laboratory for the study of biological processes.The underwater world of the national park has become famous due to the attraction it holds for divers, who rate it as one of the best places in the world to view large pelagic species such as sharks, rays, tuna and dolphins.Inscribed in UNESCO World Heritage List in 1997, the Cocos National Park belongs to the Eastern Tropical Pacific Marine Corridor, a marine conservation network, which also includes World Heritage properties in Colombia, Ecuador and Panama.The property is considered as one of the most important sites in the Eastern Tropical Pacific for the protection of large pelagic migratory species, including the endangered Scalloped Hammerhead Shark, as well as the near-threatened Silky Shark and Galapagos Shark. The Cocos Island National Park is also home to three endemic bird species, two endemic freshwater fish and two endemic reptile species.
