how the fishes manage to live under high pressure? do they have special enzyme
The water pressure is very high in deep sea. The deep sea fishes have several adaptations to manage and survive high pressure of water. They produce the same amount of pressure inside their body as they receive from outside. This internal pressure prevents them from getting crushed by extreme external pressure. Moreover they do not have excess body cavities, skeletons are reduces and the bodies are usually very soft and fluffy to withstand excess pressure.
