The special body of fish lives at a depth of 8,178 meters

Snails can be subjected to extreme pressure when living at the greatest depths in the ocean of the Mariana ocean thanks to their body full of mucus.

recorded at depths of more than 8,000 meters below sea level. The research team is headed by Mackenzie Gerringer, a deep-sea ecologist at the University of Washington, who finds the fish uses a slime-filled body to survive in extreme pressure like an elephant. On the finger, International Business Times reported on January 3.

In a study published in Zootaxa magazine, Gerringer and colleagues describe the newly confirmed species of snail that lives at a depth of 8,178 meters in the Mariana Trench located west of the Pacific Ocean. Under high pressure and temperature only 1 - 2 degrees Celsius, snail does not seem solid or body armor."You can really see the brain in their skulls , " Gerringer said.

In fact, snail fish lacked thick muscles and bones, characteristics that could help them increase their buoyancy and save energy. They also lack air pockets inside the body. Airbags help other fish to float in the water but can be crushed under high pressure. Instead, the snail's body has many layers of watery mucus that help it outperform muscles and bones, but it is harder to be compressed than airbags. This lubricant also helps them swim more effectively, according to Gerringer.

In an experiment, Gerringer created a 3D printed robot snail with a tail-wrapped bag. This bag can add water to simulate greasy tissue like jelly. When the bag was empty, Gerringer noticed that the robot fish's body produced great resistance, making swimming difficult.

However, when the bag is full of water, the robot fish body seems more flexible and swims faster. The sticky sebaceous layer of snail fish is also easy to grow because it contains mainly water.
