How can small fish survive water pressure?

Question

How can small fish (or any animal for that matter) survive deep sea water pressures - and retain their shape.

Answer 1

Because it's the same reason that scuba divers can go deep into the ocean without being crushed to pulp - the pressure on the inside is the same as that on the outside. The fish (which breathes water)
has the same pressure on the inside as the outside. It doesn't feel the pressure at all, because it's all the same. The scuba diver sues compressed air to accomplish that. The regulator steps the tank air pressure down to whatever the ambient pressure is at that depth, so the diver doesn't have to try to regulate it himself. The diver can get into trouble if they change depth drastically while holding their breath, but any proper training program will educate them about this danger. Besides, this will become painful if they try it too long, so you don't hear of this happening very often.

Answer 2

Starfish have an exoskeleton - that's a skeleton on the exterior incredibly than interior, somewhat like a shell. They get the calcium from seawater. This makes specific the starfish retains its physique shape anyplace that's - in or out of the water. some starfish have more suitable to stay in shallow water, some to stay in deep water.

Answer 3

Pressure equalization. This can occur even on the cellular level. It's why fish brought up from deep water die, and sometimes even explode!

Answer 4

because they don't have much compressable gas inside.. unlike our lungs.. and the oxygen in our blood.. they're made up of water and mostly soft tissue.. they've also evolved to live at those pressures.. i'm sure if some fish that lived at the bottom of the ocean surfaced, they'd probabl die

Answer 5

They have a high percentage of water in their bodies, and no air spaces.

Answer 6

Nothing much to collapse - no lungs full of air (like us!)
