| You may know these critters by their more menu-friendly name,
| Chilean Sea Bass.

| I really enjoyed the entire website! Good work

|
| Still very cool, and I love how it is searchable in plain text
| (eg. I can ctrl + f and type octopus and it takes me directly to
| the correct depth)

| Similar to free-diving humans, other mammals are much less

| their innate behavior minimizes the risks further -- like
| slowing their ascent as they get close to the surface?

| Not that the other replies are wrong, but it's quite

| 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].
