The animals … In fact, the pressure increases about 1 atmosphere. The deep sea varies in depth from 700 m to more than 10,000 m, therefore pressure ranges from 20 atm to more than 1,000 atm. There are four phases of matter: solid, liquid, gas, and plasma. The deep sea is dark. COVID-19 UPDATE: Following the latest update from the UK Government on its response to COVID-19 and the planned move of Blackpool into Tier 3 from December 2, SEA LIFE Blackpool will continue to remain temporarily closed. These creatures must survive in extremely harsh conditions, such as hundreds of bars of pressure, small amounts of oxygen, very little food, no sunlight, and constant, extreme cold. Extreme Fishbowl Researchers specially built an aquarium to house deep-sea creatures. Deep sea animals do not have this. Like many marine mammals, sperm whales have adapted to tolerate the effects of increased pressure when they dive in search of food. TMAO also gives rise to the distinctive fishy smell of many sea creatures – the deeper the species lives, the more it smells. The six-inch-thick plastic viewing window [above] can withstand pressure of 200 times that found at sea level. How do squid survive extreme water pressure in the deep sea? Most animals cope with this by being very small and needing less to eat or by growing very slowly. So, that's one of the amount of pressure we have on us for every 10 meters, you go down in the sea. Sperm whales have a flexible rib cage to allow their lungs to collapse at depth and expand again at the surface. Since they are all solids (most of their body) and liquids (blood, etc), they are much more difficult to compress, allowing them to survive in atmospheres with much higher pressure. Food is scarce in much of the deep sea, in part because photosynthesis only takes place at the ocean’s surface where there’s sunlight. Deep-sea animals must survive on the decaying scraps of dead organisms from the upper layers of the ocean, which sink to the bottom. This competition is now closed. How do they survive the pressure encountered on a dive as deep as 9,000ft? The simple answer is that fluids are incompressible, whereas air (in the sub) is not. On average, pressure ranges between 200-600 atm. So, it could be that deep sea creatures have over a thousand times the pressure on them that we do. Advances in deep sea technology have enabled scientists to collect species samples under pressure so that they reach the surface for study in good condition. To learn more about deep-sea marine life, sophisticated data collection devices have been developed to collect observations and even geological and biological samples from the deep.

Life in the deep sea must withstand total darkness (except for non-solar light such as bioluminescence), extreme cold, and great pressure. Most creatures have to depend on food floating down from above. Many deep sea animals produce their own light which can be used to signal conspecifics or as a weapon. ... and may help them survive the pressure. Deep-sea animals don't mind the cold at all, and many can only survive and grow in the cold. But they've evolved to live in that pressure. Many deep sea animals have large eyes or use other senses to navigate. Sound travels well through water, as do chemicals (scent or taste depending on the receptor). The term deep sea creature refers to organisms that live below the photic zone of the ocean. ... For many deep sea animals, the deeper they live the more TMAO they have in their bodies.
