Filming fishes live in the greatest depth

Scientists filmmaking in one of the deepest trenches in the ocean floor recently discovered a fish like a tadpole that lives in a flock gathered around the bait. They live at a depth of nearly 5 miles (7700 m) below the surface of the Pacific Ocean. This is the first time the camera has been taken to such a great depth.

On the Japanese research ship Hakuho-Maru, project leader Dr. Alan Jamieson from the Oceanic Laboratory (University of Aberdeen) said: 'We have achieved incredible footage at a depth of 7700 m. . There are more fish than anyone imagined around the world for such a depth. ' And Professor Monty Priede, director of the laboratory, said: 'It is so wonderful. The film has surpassed our prediction in research. We think that the fish that live at the greatest depths are still immobile, live lonely and weak in a food-deficient environment '.

'In contrast, the fish are not alone. The photograph shows that they live closely and positively, probably different fish families. They live on small shrimps, they are now living in one of the harshest environments on earth. '

Professor added: 'All we see about life at such depths is narrowed in specimens at the museum. Now we have the impression of the form of movement and the activities of the creatures on the ocean floor. When we see them moving so fast, we think that the snailfish seems to be misplaced. '

Although some species of snail live in shallow water or even in rocky areas, they also have species only in deep water above 6000 m. Here they were forced to be satisfied with the darkness completely, the temperature was close to freezing and the water pressure was enormous - at this depth, the pressure was about 8,000 tons per square meter equivalent to the gravity of 1600. The elephant stands on the roof of a Mini car . They eat thousands of tiny shrimp-like organisms, which feed on dead fish or debris that fall to the sea floor.

Slugfish live at depths above 6000 m only appear in the Pacific slots, with many different species limited in each region including: Chilean and Peruvian slots in South America, Kermadec and Tonga slits bordering Samoa and New Zealand in the South Pacific, and slots in the Pacific Northwest (Japanese slit being studied by Priede's group).

This study is part of Oceanlab Marine Laboratory HADEEP project. This is a collaborative research program with the University of Tokyo planned by Priede to understand life in the environment more than 6000 meters deep in the ocean. The expedition was funded by the Natural Environment Research Council and the Nippon Japan Foundation. The expedition began on September 24 and ended on October 6.

Specialized devices that can withstand extreme pressure at this depth are designed and built by the Oceanlab team. The camcorder takes 5 hours to reach the depth of the slot , it is located on the seabed two days before the signals are sent over the water.
