No wonder this fish looks like a swollen balloon – it has been holding water for centuries.
This strange little creature is known as Chaunax endeavor and lives in the deepest part of the Pacific Ocean. The researchers first observed this amazing behavior when they crossed publicly accessible videos taken by remote controlled National Oceanic and Atmospheric Administration (NOAA) vehicles.
Scientists have found pictures of eight different coffins in the water they took.
To get the oxygen needed to survive, fish swallow water (consisting of two parts of hydrogen and one part of oxygen), extract oxygen and then “exhale” oxygen-poor water, releasing it from the gills. But these fish store water in their large gills for a long time from 26 seconds to 4 minutes instead of releasing it immediately.
Scientists have also carried out CT scans of samples of coffins to examine massive gill spaces where animals store water.
As far as the reasons for fish are concerned, the researchers assume several assumptions. They say stopping breathing can help fish save energy. He can even protect them by making them look bigger than predators. If the skin is stored in water, the body’s volume will increase by 30% according to the study.
