Cocos Island (Isla del Coco) is an island located off the shore of Costa Rica. It constitutes the 11th district (one of 13) of Puntarenas Canton of the province of Puntarenas. It is one of the National Parks of Costa Rica. It is located in the Pacific Ocean, approximately 550 km (340 mi) from the Pacific shore of Costa Rica , at . With an area of approximately 23.85 km² (9.2 mi²), about 8×3 km (5×1.9 mi) and a perimeter of around 23.3 km 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 Galapagos Archipelago or any of the other islands (e.g., Malpelo or Coiba) in this region of the world
Cocos Island is an oceanic island of both volcanic and tectonic origin. It is the only emergent island of the Cocos Plate, one of the minor tectonic plates. An Argon–Potassium radiometric determination established the age of the oldest rocks between 1.91 and 2.44 million years (Late Pliocene) and is composed primarily of basalt, which is formed by cooling lava. The landscape is mountainous and irregular and the summit is Cerro Iglesias at 575.5 m . In spite of its mountainous character, there are flatter areas between 200–260 m in elevation in the central part of the island, which are said to be a transitional stage of the geomorphological cycle of V-shaped valleys . With four bays, three of them in the north side (Wafer, Chatham and Weston), Cocos Island has a number of short rivers and streams that drain the abundant rainfall into them. The largest rivers are the Genio and the Pittier, which drain their water into Wafer Bay. The mountainous landscape and the tropical climate combine to create over 200 waterfalls throughout the island. The island's soils are classified as entisols which are highly acidic and could be easily eroded by the Island's high rainfall on the steep slopes, were it not for the dense forest coverage.
Cocos Island is home to dense and exuberant tropical moist forests. It is the only oceanic island in the eastern Pacific region with such rain forests and their characteristic types of flora and fauna. The cloud forests at higher elevations are also unique in the eastern Pacific. The island was never linked to a continent, so the flora and fauna arrived via long distance dispersal from the Americas. The island has therefore a high proportion of endemic species.
The inland forests extend from 50 to 500 meters elevation. "Palo de hierro" or huriki (Sacoglottis holdridgei), "avocado" (Ocotea insularis) and the endemic Cecropia pittieri are the most common canopy trees. The trees are festooned at all levels with epiphytic plants, including as orchids, ferns, bromeliads and mosses. The understory includes sedges such as Hypolitrum amplum and various species of ferns and tree ferns including Cyathea armata and Danaea media. The endemic palm Rooseveltia frankliniana is also common.
Cloud forests are found at the highest elevations, over 500 meters. Melastoma spp. is predominant.
The island has over 400 known species of insects, of which 65 (16%) are endemic. The greatest diversity is found among the Lepidoptera and Formicidae. Over 50 species of other arthropods have been described (spiders, centipedes, millipedes, and isopods), including the endemic spider
Nearly 90 bird species have been reported. The island and neighboring rocks are home to large nesting colonies of migratory seabirds, including the Brown Booby (Sula leucogaster), Red-footed Booby (Sula sula), Great Frigatebird (Fregata minor), White Tern (Gygis alba) and Brown Noddy (Anous stolidus). Seven species of land birds inhabit the island, including three endemics: the Cocos Cuckoo (Coccyzus ferrugineus), Cocos Flycatcher (Nesotriccus ridgwayi) and Cocos Finch (Pinaroloxias inornata).
The island has five land mammal species, including pigs, deer, cats and rats. All these land mammals were introduced by humans. The Costa Rican government has vowed to control the populations of these animals, as they are harmful to the local ecosystems.
The rich coral reef, volcanic tunnels, caves, massifs and deeper waters surrounding Cocos Island are home to more than 30 species of coral, 60 species of crustaceans, 600 species of molluscs and over 300 species of fish. These include large populations of yellowfin tuna (Thunnus albacares), giant mantas (Manta birostris), sailfish (Istiophorus platypterus) and sharks, such as white-tips (Triaenodon obesus) and hammerheads (Sphyrna lewini). The largest of all species of fish is also present, the whale shark (Rhincodon typus).
Other large marine animals include humpback whales (Megaptera novaeangliae), pilot whales (Globicephala macrorhynchus), bottlenose dolphins (Tursiops truncatus), sea lions (Zalophus californianus), hawksbill turtles (Eretmochelys imbricata), green turtles (Chelonia mydas) and olive ridley turtles (Lepidochelys olivacea).
J. Lines (Diario de Costa Rica, May 12, 1940) cites Fernández de Oviedo who claims that the first discoverer of the island was Johan Cabeças. Other sources claim that Joan Cabezas de Grado was not a Portuguese sailor but an Asturian. D. Lievre, Una isla desierta en el Pacífico; la isla del Coco in Los viajes de Cockburn y Lievre por Costa Rica (1962: 134) tells that the first document with the name "Isle de Coques" is a map painted on pergamen, called that of Henry II that appeared in 1542 during the reign of Francis I of France. The planisphere of Nicolás Desliens (1556, Dieppe) places this Ysle de Coques about one and half degrees north of the Equator. (See also Mario A. Boza and Rolando Mendoza, Los parques nacionales de Costa Rica, Madrid, 1981.) Blaeu's Grand Atlas, originally published in 1662, has a colour world map on the back of its front cover which shows I. de Cocos right on the Equator. Frederik De Witt's Atlas, 1680 shows it similarly. The Hondius Broadside map of 1590 shows I. de Cocos at the latitude of 2 degrees and 30 minutes northern latitude, while in 1596 Theodore de Bry shows the Galapagos Islands near six degrees north of the Equator. E. Bowen, A Complete system of Geography, Volume II (London, 1747: 586) tells that the Galapagos stretch 5 degrees north of the Equator.
In October 1863 the ship the "Adelante" dumped 426 Polynesian ex-slaves on the island, the captain being too lazy to bring them home as promised. When they were saved by the "Tumbes", one month later, only 38 were left over, the rest had already perished from smallpox. (See: 'Ata).
In 1897 the Costa Rican government named the German adventurer and treasure hunter August Gissler the first Governor of Cocos Island and allowed him to establish a short-lived colony there.
Cocos Island officially became part of Costa Rica by the promulgation of the Constitution of Costa Rica on November 7, 1949. On May 12, 1970 the insular territory of Cocos Island was incorporated administratively into Central Canton of the Province of Puntarenas by means of Executive Decree No. 27, making it the Eleventh District of Central Canton.
Thanks to the breathtaking marine life in its waters (see fauna section above), Cocos Island was named one of the best 10 scuba diving spots in the world; a "must", according to experts. For many, the main attractions are the large pelagic species, which are very abundant in this unique meeting point between deep and shallow waters. Some of the largest schools of hammerhead sharks in the World are consistently reported there. Encounters with dozens if not hundreds of these and other large animals are nearly certain in every dive. Smaller and colorful species area also abundant in one of the most extensive and rich reefs of the south eastern Pacific. The oceanographer Jacques Cousteau visited the island several times and in 1994 called it "the most beautiful island in the world".
The only persons allowed to live on Cocos Island are Costa Rican Park Rangers, who have established two encampments, including one at English Bay. Tourists are allowed ashore only with permission of island rangers, and are not permitted to camp, stay overnight or collect any flora, fauna or minerals from the island. The islands' 33 residents, the Costa Rican park rangers, were allowed to vote for the first time in Costa Rica's February 5, 2006 election. This island is popular in pirate lore as well. It is said that over 3 hundred expeditions have gone in search of treasure from the likes of Benito Bonito, and many others. Some incidents of small caches have been discovered, leading many to believe the stories of vast pirate treasures to be valid.
Recent events show that large-scale illegal poaching keeps happening. Despite initial hope in stopping and charging poachers, who have been caught with abundant evidence, they have been quickly released under suspicious circumstances. Also, efforts to raise funds for protection have been dwarfed.
Marvin Orlando Cerdas, a judge with the local Puntarenas Court of Justice, obscurely allowed 22 poachers caught red-handed to escape the country.
Also under highly suspicious and allegedly corrupt circumstances, the District Attorney Michael Morales Molina, stopped the auction for public benefit of confiscated goods, immediately after the spokesman of the large illegal poacher ship "Tiuna" simply made the request.
Robinson's neighbouring Terra Firma is shown on the colour map of Joannes Jansson (Amsterdam) depicting the northeastern corner of South America, entitled Terra Firma et Novum Regnum Granatense et Popayan. It belongs to the early group of plates printed by William Blaeu from 1630 onwards. The properly called Terra Firma was the Isthmus of Darien . Crusoe's two references to Mexico are against a South American island as well.
The Michael Crichton novel Jurassic Park centers on the fictitious Isla Nublar that is off of the west coast of Costa Rica. Isla del Coco may be the inspiration for this island. Supporting this argument is the Dreamworks Interactive game Jurassic Park: Trespasser (1998) which used Cocos Island's topography as a substitute for the fictional island on which it takes place. Also, "Isla Nublar" is intended to mean "Clouded Island", and Cocos Island is the only island with cloud forests in the eastern Pacific.
