Due to its remote location and being in a confluence of streams, it is very rich in nutrients, which activates a very complete trophic chain, from small schools of life to large pelagic ones.
Cocos Island is located 300 miles from the coast in the Pacific. The amount of sharks that can be observed is surprising, some divers even qualify them as better than the Galapagos themselves.
Obviously it is a destination for liveaboard diving, our boats make a 10-night tour on board to enjoy the most of the diving in these waters, since it takes a whole day to arrive and another day to return. Although you can dive all year round, it is best to avoid the months of July and August because the sea is in poor sailing conditions with large waves that can make the trip difficult. In this destination only experienced divers can access, the depth, currents and type of drift dive do not make it a place for beginners.
The island of the Cocos is popularly known as “Isla del Coco” in the native language of Costa Rica. At the end of the 90s, the island was declared a National Marine Park and a World Heritage Site by UNESCO. The waters of Coco Island are full of impressive marine life, in fact divers come to this island to dive with one of its main attractions, the great schools of hammerhead sharks.
The island has an irregular coastline, which makes the precise estimation of its land area more a matter of opinion than the science of a surveyor, but it is approximately five miles by two miles (8 x 3 kilometers). Cocos Island was formed during a volcanic uplift about two and a half million years ago and is composed of basalt rock, labradorite and andesite lava flows. Its surface is dotted by four mountain peaks, the highest of which is Cerro Iglesias, which reaches 634 meters above sea level.
Among the many attributes of Cocos Island is a surprising degree of biodiversity. The waters of this world-renowned island explode with life, including innumerable whitetip reef sharks, hammerheads, dolphins, manta rays and rays, giant moray eels, sailfish and, of course, the whale shark. Other common meetings are the large schools of horse mackerel and tuna, silky sharks, silver tips, marlins, creole fish, green turtles and octopuses.
The island of Cocos also hosts at least 27 endemic species of fish, including the exotic pink-lipped batfish. The terrestrial life in Cocos also exhibits a high number of endemic species. The island hosts 70 of the 235 species of vascular plants identified in the world, some 25 species of moss, 27 species of liverworts and 85 species of fungi. There are more than 87 species of birds, including the famous cuckoo of Cocos Island, the finch and the flycatcher. There are 362 species of insects, of which 64 are endemic. Two native reptiles are found only on the island.
Under the waterfalls and in the rivers, there are freshwater fish that baffle scientists for their very existence. Due to its remote location and the abundance of fresh water, Cocos has been, throughout history, a favorite refueling station for pirates, whalers and sailors.
