Cocos Island
Cocos Island (Spanish: Isla del Coco) is an island designated as a National Park off the shore of Costa Rica, that does not allow inhabitants other than Costa Rican Park Rangers. It constitutes the 11th of the 13 districts of Puntarenas Canton of the province of Puntarenas. It is located in the Pacific Ocean, approximately 550 km (342 mi) from the Pacific shore of Costa Rica. With an area of approximately 23.85 km2 (9.21 sq mi), about 8 km × 3 km (5 mi × 2 mi) and a perimeter of around 23.3 km (14.5 mi), this island is more or less rectangular in shape.Surrounded by deep waters with counter-currents, Cocos Island is admired by scuba divers for its populations of hammerhead sharks, rays, dolphins and other large marine species. The extremely wet climate and oceanic character give Cocos an ecological character that is not shared with either the Galápagos Archipelago or any of the other islands (e.g., Malpelo or Coiba) in this region of the world.
