How have deep-sea fish adapted to high water pressure?

Answer 1

In my reserch I have found that they don't actually adapt, it's the way there body structure is made. The animals' bones are so stong they will not break from all the presure. Sometimes they are just extremely flexable so they aren't crushed like the octopus. If I didn't answer your question correctly just try to disscuss it with me. - The 11 year-old

OK! I will! You are nearly there. It is a matter of body structure and flexibility, but their bones do not need to be ever so strong because their bodies' internal pressures balance those of the surrounding water. Some fish and deep-diving whales swim up and down over considerable ranges of depth because their bodies' internal pressures adjust automatically.

Human divers manage in the same way because they breathe air through a valve that automatically adjusts the air-pressure to the water's, and this adjustment is transferred to the body generally.

Answer 2

The animals have a developed ways to cope with the deep ocean's intense water pressure. This force, which is the result of the weight of a column of water pushing down, is so strong in the bathypelagic zone that it would crush anything with air in it. That would be a problem for most fish, since many of them have a gas-filled organ called a swim bladder a large, thin-walled sac in some fishes that may function in several ways, e.g., as a buoyant float, a sound producer and receptor, and a respiratory organ. that helps them stabilize their bodies at different water depths. But many deep-sea fish have adapted to life without a swim bladder. Without the bladders, "[deep-sea fish] don't have gas spaces in them that would cause them to get crushed,"

Answer 3

Deep-sea fish have adapted to high water pressure by having flexible bodies and reduced gas-filled cavities to avoid the effects of pressure changes. They also have special proteins and enzymes that work efficiently under high pressures, allowing them to function normally at depth. Additionally, some deep-sea fish have lipid structures in their cell membranes that help maintain fluidity under high pressure conditions.
