Not that the other replies are wrong, but it's quite predictable from an evolutionary perspective that the physiology adapts for a range of different environments. Many animals can withstand a large range of temperature, so why not a range of pressure too, as long as it can benefit the animal? To me, it's more fascinating that land animals like humans can survive at all at ~50x the highest pressure on land. Another fascinating remnant of our oceanic ancestry is the mammalian diving reflex[1]. [1]: https://en.wikipedia.org/wiki/Diving_reflex https://en.wikipedia.org/wiki/Diving_reflex
