Scientists filmed octopus 7km deep in Indian Ocean (Video)

Scientists filmed an octopus at the largest known depth so far - 7km away in the Javan Trench of the Indian Ocean, the BBC reported.
That's 2km deeper than the previous record holder, filmed 50 years ago at 5km deep. Scientists describe the find in the Marine Biology.

Octopus is a representative of the species “Dumbo”. The name is because of the ear-like fins just above the eyes that are reminiscent of the Disney movie character.

The pictures are taken with descending devices, which are positioned at the bottom and capture what passes by them. Two octopuses were filmed - one at a depth of 5.8 km and the second at a depth of 6.96 m. The specimens are 43 cm long and 35 cm long, BTA complements.

Pieces of octopuses and caviar were found at great depth. Before this photo, the record-holder was an octopus, descended 5.15 km. It was made 50 years ago in the Caribbean Sea.

Observations in the Indian Ocean show that octopuses can find a suitable habitat in at least 99 percent of the world's seabed. However, those who live at vast depths must have adapted specifically, points out Dr Alan Jamieson, who made the discovery.

"They have to do something cunning in their cells. If you imagine the cell as a balloon, it would burst under pressure. Therefore, some unusual biochemistry is needed to remain spherical,” he explains. “All adaptations for life under pressure are at the cellular level.”

Dr. Jamieson filmed the octopus in his capacity as chief scientist of the Five Depths expedition. For this project, Texas financier Viktor Veskovo has descended by descending apparatus to the deepest sectors of the five major oceans. While he was setting records as a diver, Dr. Jamieson was doing scientific research.
