MOUNTAIN SYSTEM ALLOWS 'TRANSIT' OF MANY SPECIES
Cocos Island emerges from submerged volcanic mountain range in the Pacific
Scientists evaluate different ways of life in shallow and deep
Underwater Deep See help you learn fauna to 300 m depth

Coco Island is the only point emerged, and therefore, the highest, a volcanic mountain range that protects its secrets under the Pacific Ocean.
The volcanic mountain range extends Coco over 780 kilometers and is estimated to have about 100 giants. Some of its mountains are less than 1,000 meters below sea level.
The peaks or tops of these mountains serve as a basis for agencies to move or be moved from side to side. "They go from one mountain to another like stones to cross a river and is likely to reach the island some marine organisms that move through these underwater mountains," said Jorge Cortes, a scientist of the Center for Science Research and Limnology (Cimar-UCR).
Cortes is one of the few Costa Ricans have been submerged in the depths of the Cocos Island. thanks to the sub Deep See , owned by diving Undersea Hunter, an ally of Cimar in these studies.
Although it has ability to download up to 400 meters, most of the dives performed by Deep See are between 100 and 300 meters.
During the dives have taken photographs and videos of specimens. Thanks to a mechanical arm, the submarine has been allowed to take samples of dead coral or rocks covered with little creatures of the sea.
According to Cort?s and the scientific report Scmulik Blum in the Journal of Tropical Biology , there have been carnivorous fish (such as Lophiodes spilurus ), colorful jellyfish (Class Scyphozoa) and dark coral.
Life at depth. The Coco Island is the summit of a volcano. If he is seen in profile, this seems to have two tiers, said Cort?s.
The first is a platform of 18 kilometers long, with a southwest-northeast. It is located 180 meters deep.
When this finishes, you see a slope that drops some 2,000 feet to the base of the volcano. This is known as "the wall."
In the ocean, the water is stratified: the hot water is up and the cold water is below.
Therefore, as the sub descends, the researchers can distinguish two very different water layers.
Coco In this division occurs at 50 meters, called thermocline, an area where there is a drastic change in water temperature. Going from 28 ? C to 15 ? C.
The thermocline divides the water column into two "apartments": shallow (superficial) and deep. Each floor has its agencies.
In the shallow, 1,400 species have been identified.
"In deep water is different from other wildlife. There are probably many new species, but still we are studying, "he acknowledged Cort?s.
Coco is close to a depth of 165 meters peaks are called Coco and the twins. According to Cort?s, is like watching Coco Island, but collapsed. There are two outstanding peaks and a valley of sand. "These peaks are only mountains that reached the surface," he said.
Other organisms that live there to fascinate experts. For example, a mollusk that is common in the shallow waters of Baja California, Mexico.
