Deep-sea fish resist crushing pressure due to their special adaptations. They balance internal and external pressures. Their bodies contain mostly water, which reduces air pockets that could collapse. Proteins like trimethylamine oxide (TMAO) and unique anatomical structures help them survive in dark, extreme-pressure environments. Deep sea fish also have specialized proteins and cellular mechanisms that … Read more
