Diving Pelagics Cocos Island Costa Rica

While constantly attacked by large predators, the many hundred small Green Jacks maintain the tight ball formation. Drifting logs offer shelter to schools of small fish, at the same time the abundant food supply under the log attracts sharks and other large predators. Dolphins often arrive first to the schools and are extremely adept at hording the small fish into a tight ball. Sharks appear soon after.

Cocos Island is also home to at least twenty seven endemic fish species including the exotic red-lipped batfish. The terrestrial life at Cocos also exhibits a high number of endemic plants. Here there exist around seventy out of the two hundred thirty five identified vascular plant species in the world, some twenty five species of moss, twenty seven species of liverwort and eighty five species of fungus. There are upwards of eighty seven bird species, including the famous Cocos Island cuckoo, finch and flycatcher. There are three hundred sixty two species of insects, of which sixty four are endemic, and two native reptiles.

Among Cocos Island’s many attributes is a startling degree of biodiversity. This Island’s world-renowned waters explode with life; including innumerable white tip reef sharks, schooling hammerhead sharks, dolphins, mantas and marbled rays, giant moray eels, sailfish, and of course the occasional whale shark. Other common encounters are large schools of jacks and tuna, silky sharks, silver tip sharks, marlin, Creole fish, green turtles and octopus.
