The depths of the ocean are festooned with the most nightmarish creatures conceivable You would possibly assume you’re safe, as a result of these critters dwell 1000’s of toes down in a chilly dark abyss, however the vampire squid, which appears to be like like a nightmare umbrella, and the frilled shark’”a literal dwelling fossil’”will dwell on within the recesses of your mind long after you’ve got clicked away. What allows fish to dive to depths of over 25,000 toes is the presence of a particularly hydrophilic substance called trimethylamine oxide (TMAO), which prevents the distortion and compression of proteins and different important molecules inside the physique under intense external stress.
For creatures like the beaked whale, which is arguably the deepest diving cetacean (just below 10,000 feet), stress is certainly an issue, however they’ve a wide range of diversifications to accommodate their deep-sea lifestyle decisions.

When sharks do assault individuals, it is most likely as a result of they mistake people for seals or different giant ocean animals that they wish to eat. It’s because chilly water can dissolve extra oxygen than heat water, and the deepest waters usually originate from shallow polar seas.
Second, Heim and colleagues present that most of the general improve in physique measurement throughout all marine animals is explained by the evolution of main new groups, with the entire anatomical and physiological innovation that means. Fishing traces and nets make no distinction between goal species and animals who should not targeted – they scoop up all animals in their paths.
