Snail fish discovered in the deep sea of Japan (melts quickly when landed)

In the vast deep sea, there must be many secrets that are currently unknown to mankind, which has also attracted the continued attention of many scientists. News on April 3, according to media reports, scientists photographed Snailfish in southern Japan. They used an automatic machine called "Landing" to photograph this snail in the Izu-Ogasawara Trench in southern Japan, also at 8,336 meters under the sea. fish. Snailfish are suckers that feed on tiny crustaceans found in ocean trenches. They currently have no natural predators, and once fished ashore, they will instantly "melt" into jelly.

Prior to this, the record of fish found on the deepest seabed was 8,178 meters underwater in the Mariana Trench. With this new discovery, this record has been extended by 158 meters. Scientists speculate that the Izu-Ogasawara Trench The water temperature is warmer than that of the Mariana Trench, which may be why fish can survive in deeper water.

A long time ago, scientists have believed through research that the maximum limit for fish to survive in the deep sea may be between 8,200 meters and 8,400 meters below the sea level. One figure shows that the pressure on fish in the sea below 8,000 meters is 800 times the sea surface pressure.

It is understood that there are about 300 kinds of "snail fish", most of which are actually shallow-water creatures. However, because they do not have a swim bladder and a gel-like body, they are extremely adaptable. However, once this fish is fished ashore, it will melt instantly. Become "jelly-like".

The reason why they are so amazing is that research believes that in order to adapt to this extreme living environment, their bodies have evolved into a soft jelly-like state. This state can withstand high pressure and low temperature, but it also needs to rely on extremely high water pressure and extremely cold environments. The supporting bodies, once they float to the surface, will no longer be able to maintain their original bodies due to changes in pressure and temperature, and will quickly melt.
