Giant amoebas have been discovered in the depths of the ocean

Giant amoebas have been discovered oceanographers at the bottom of the Mariana Trench, the deepest region on Earth. In July 2011, during an expedition into the deepest crevice of the Pacific Ocean, researchers with the Scripps Institute of Oceanography, University of California, San Diego, and the crew used a Geographic Channel Neyshnl deep-sea vehicle called "dropkem", equipped with a digital video and lighting, with a view to explore a huge mysterious depths of the sea.

The research team has documented the existence of ksenofioforov, single-celled animals that live exclusively in deep-water environments. Ksenofiofory deserve attention because of their size, special cells, often reaching more than 4 inches (10 centimeters), a hearty spread on the bottom of the sea, and the role of habitat for a variety of organisms.

Researchers have found evidence of life forms in the deepest point of the Mariana Trench, called "The Abyss Challenger", located at a depth of 6.6 miles (10,641 meters). In a previous study ksenofioforov dwelling was recorded in the New Hebrides Trench, at a depth of about 4.7 miles (7500 meters).

Scientists claim that ksenofiofory are the biggest features of the cells of the other life forms that live at great depths. Recent studies indicate that ksenofiofory, capturing particles of water are able to concentrate high levels of lead, uranium, mercury and thus are likely to resist the effects of high doses of heavy metals. They are also well adapted to life in the dark, the conditions of low temperature and high pressure at the depth of the sea. Ksenofiofory are essential to the ecosystem of the deep sea environment. The expedition also found a jellyfish and other mysterious animals, many of which still have not been able to identify.

"As one of the creatures found exclusively in the deep sea, ksenofiofory - incredible giants that are very adapted to live in extreme conditions, but at the same time very fragile and poorly studied," - said one of the researchers. "These and many other important structural organisms living in the deep seas, need to be protected as a human activity begins to descend lower and lower."

To explore the depths of the ocean, scientists used only the most modern technology, including special camera developed by U.S. experts. Put in a glass bubble that can withstand the pressure of a big depths, cameras allowed oceanologists get crisp, high quality images of underwater life. "Deep-sea animals were brought to the camera with bait, a technique first developed by Scripps Professor, John Isaacs (John Isaacs) in 1960" - said Kevin Hardley (Kevin Hardy), member of the expedition and a member of the Scripps Institution of Oceanography.
