The lowest temperature in this zone is nearly -4 Celsius but the water doesn't freeze because the water pressure is so high. The salinity amount of salt in the water) ranges from 35-37 ppt. (parts per million). The depth of this zone ranges between 200 meters to 9,000 meters.
it's deep depths and tempretures
Deep ocean hydrothermal vents are an extreme environment due to high temperature and pressure, toxic chemicals like hydrogen sulfide, and absence of sunlight. Organisms living near these vents have adapted to thrive in these harsh conditions by relying on chemosynthesis rather than photosynthesis for energy.
Extreme pressure.
Jellyfish have been seen at extreme depths in oceans.
These themophiles would be classified as archeabacteria. These bacteria inhabit extreme living conditions such as high heat and high pressure.
The fangtooth fish primarily inhabits the bathypelagic zone of the ocean, which ranges from 1,000 to 4,000 meters deep. This deep-sea fish is adapted to the extreme pressures and low light conditions of these depths.
The deep sea is often referred to as the "abyssal zone" or "deep ocean." It typically encompasses regions of the ocean that are deeper than 1,000 meters (about 3,280 feet), where light penetration is minimal and pressure is extremely high. This vast and largely unexplored environment is home to unique ecosystems and organisms adapted to extreme conditions.
A cold and salt tolerant crab would likely be found in the polar regions of the ocean where temperatures are cold and salinity levels are high. These crabs have adapted to thrive in these extreme conditions.
The deepest part of the Arctic Ocean is the Molloy Deep, located in the Fram Strait between Greenland and Svalbard. It reaches a depth of about 5,550 meters (18,210 feet). This area is characterized by extreme conditions and is relatively less explored compared to other ocean depths.
Deep-sea animals such as lanternfish, hatchetfish, and vampire squids are known to inhabit the Twilight Zone, which is the region of the ocean between 200 and 1000 meters deep. These animals have adapted to survive in the low light conditions and extreme pressures of this deep-sea zone.
Animals in the deep ocean experience extreme pressure, darkness, and cold temperatures. They have adapted to survive in these harsh conditions by developing unique physiological and behavioral adaptations, such as bioluminescence and the ability to withstand immense pressure. They often rely on scavenging for food due to the limited availability of prey in these deep-sea environments.
Scientists refer to the organisms that live below the bottom of the ocean as extremophiles, which are organisms that thrive in extreme environments. These organisms have adapted to survive in conditions such as high pressure, darkness, and extreme temperatures that are present in the deep sea.
