Catch the animal that lives in record depth

Three new marine shrimp were caught at a depth of 2,300 meters on hot water slots in the mid-Atlantic mountains.

The difficulty of the researchers is how to maintain their normal life when brought to the surface, by the sea floor, the pressure is great, even on the water surface, the pressure is almost zero. When pulled to shore, under pressure maintained like the seabed, the shrimps still swim actively, but when the pressure is lowered, they twitch and die within a few hours.

Dr. Bruce Shillito, marine biologist at Pierre University in Paris, France, and his colleagues designed a new device that allows the survival of organisms under their natural pressure when brought to the surface. .

The team's next step is how to transfer these organisms from a sampling device into a better equipped experimental tank without having to reduce the pressure, allowing them to observe the usual behavior of they and responses to habitat change.

In the past, people were able to reproduce the pressure for living organisms at a record depth of 1,400 meters.
