These creatures have several adaptations like compressible lungs, lung-like swim bladders, and so forth, to help them overcome the high water blackmail in their deep-water environment .
adaptation of the Deep Sea Creatures to High Water atmospheric pressure
ideally, high pressure in the deep ocean should crash the ocean creatures. But, the incredible fact is that many marine and fish species survive even at the highest possible pressure found american samoa deep as 25,000 feet below the sea surface. Before diving into the water, many deep-sea creatures exhale closely 90 % of the vent in their lungs and keep only around10 % of the oxygen available for their function. The survival of the marine creatures in less oxygen provision is made possible by several factors .
Holding The Breath For Hours
Some whales and seals have shocked the populace with their resilience in hard-hitting deep-sea waters. For example, the Cuvier ’ sulfur beaked giant can dive angstrom deep as 2,992 meters and withhold its hint in body of water for a read 2 hours and 18 minutes. On the other hand, the elephant seal can hold its breath in water for 2 hours .
completely compressible Lungs
The beaked giant is the deepest dive cetacean. Under coerce, its lung collapses forcing all of the gas in its lungs out into the muscles and bloodstream where the gasoline is dissolved. The muscles are adapted to hold more myoglobin while the blood possesses more hemoglobin for storage of oxygen. Collapsing of the lungs results in reduce air out pockets and minimal oxygen available for its survival .
Lowered Heart Rate
In some creatures, the heart rate is minimized to about 4 beats per hour while others stop breathing for a while when diving into the deep-sea .
Some deep-sea creatures reduce their drift so that they glide rather than swim downwards. Gliding is a procedure that requires no muscle apparent motion ; saving the creatures ’ oxygen for habit on their travel back to the water surface.
Lowered Metabolic Activity
Under high barometric pressure, some deep-sea creatures such as whales and seals shut down their digestion, liver, and kidney functions .
lung-like Swim Bladders
A group of deep-sea creatures have lung-like float bladders which help in controlling their buoyancy. The swim bladders do not collapse because in the deep sea the gas inside is equivalent to the coerce of the water external.
presence Of Trimethylamine Oxide ( TMAO )
presence of TMAO in deep-sea fish prevents the distortion and compression of proteins and early vital molecules within the consistency under intense external atmospheric pressure .
No Nitrogen Absorption
miss of nitrogen absorption at deep blackmail prevents the development of nitrogen narcosis and decompression sickness .
