How Do Deep Sea Fish Survive the Extreme Pressure?
Показать описание
Fishes survive underwater pressure as they do not breathe through their lungs. Therefore, they do not have air pockets that can be compressed due to the high pressures.
However, fish aren’t the only creatures found at such incredible depths. Some whales, seals, and other cetaceans are able to dive to depths of nearly 10,000 feet. The lungs of these creatures are completely compressible, meaning that they can force all of the gases in their lungs into their bloodstream and muscles, where they can essentially dissolve under pressure. These organs have adapted to hold more myoglobin (oxygen-storing protein in muscles) and hemoglobin.
This collapse of the lungs also prevents gas exchange at the alveoli, thus preventing nitrogen from entering the bloodstream, which would result in the infamous “bends” that human deep-sea divers can experience if they rise from great depths too quickly.
