Where it is abissais adventure in the depths of the oceans in regions where the sunlight is not enough and pressure esmagaria a being of the surface, the biologists often encounter unknown species. They are fish, octopus, squid and water-that live along the evolution acquired surprising appearance to be adapted to the hostile environment in which they live. There are currently five submarines, two Russians, one American, one French and one Japanese, which make searches in the waters over 3000 meters deep. Every two species they record, an unknown era of science. A collection of 220 of these recent discoveries was collected in a book recently launched in the United States, The Deep: The Extraordinary Creatures of the Abyss (The Profundezas: The Extraordinary Creatures of Abismo) of the researcher and producer of films Nouvian Claire French. Most of the animals was photographed in their natural environment by cameras installed in submarines manned or robotic divers, able to descend to up to 6000 meters. Others were photographed on the deck of the boat after it is brought to the surface in special chambers that keep the pressure of the seabed. Although there are more species in the deep waters of what is imagined, the population density of each of them is small compared to that of species that live near the surface. Therefore, the evolution favored the animals able to face shortages of food and sex partners. Fish male of the species Ceratias holboelli when found a female, grudam it and undergo a metamorphosis: their activities vital adormecem and they saw a parasite whose only asset is the body pool of sperm.
One way to facilitate the meetings in the darkness is bioluminescence. This phenomenon occurs when fish, octopus and other bodies emit light own or live in partnership with luminous bacteria. The lights attract partners of the same species. The bioluminescence also serves as bait to fish carnivores attract their prey. Some species of a type of bait rod with a light at the tip which is only a few centimeters in front of the mouth. When a prison is approaching, it is immediately swallowed. As there is no sunlight in the deep oceans, the source of life in these places are the heat and methane gas released by cracks in the earth''s crust or by submarine volcanoes. This environment provides the birth of bacteria, which are beginning to a new and still almost unknown food chain. What already is known with certainty about the lives of more than 3000 meters deep is that it reproduces the parameters governing all animals known. While weird and even frightening to look at humans, animals abysses of the ocean have nothing original, in its constitution, which confirms the discovery of naturalist Charles Darwin that all living things have a common ancestor.
