Marine life also counts




For the first time in history, experts from around the world have met to talk at length about the life of the oceans at the First World Congress on Marine Biodiversity, held in Valencia, Spain. It has presented the progress of the project that, in the year 2000, brought together thousands of scientists from 82 countries with a common goal: to explore the biodiversity of the oceans. Although the catalog of species will not be completed until 2010, the Marine Life Census (CoML), as this network is known, has already provided some interesting data. For example, researchers have found evidence that first evidence that a large proportion of octopus species from around the world evolved from a common ancestor that still lives in the Antarctic. In this same ocean, giant starfish have been identified. And the Pacific has surprised us with a white shark coffee? and a "sturgeon park".



Biologists do not want to leave anything behind. For they are exploring from the intertidal zones shared with humans to the dark trenches of more than 10,000 meters deep, from the microscopic plankton of the illuminated areas of the sea and the sea lions that dive in the depths to the worms that inhabit the abysmal sediments , from the organisms that live in the changing slopes of the seamounts to those that tolerate fiery oceanic sewers. In other words, 5% of the oceans that are regularly visited and 95% whose life remains unexplored.
