Question

a large variety of marine invertibrates and fish live at great depths in the oceans where the pressure could be more than 100 times more than thenormal atmospheric pressure that we experience . how do they live under such crushing pressure

Answer 1

To tolerate such a crushing pressure marine invertebrates and fishes show some adaptations like:-

Their cell membrane has more number of unsaturated fatty acids to increase the fluidity and their enzymes have specific structure. Most of the enzymes are monomeric and they have amino acids that make strong non covalent bonds between them to increase the stability.
