Ever wonder what lives at various depths of the ocean? Try neal.fun. I had no idea polar bears could be found, living one hopes, at 25 meters, or about 75 feet. I do see a claim that the bird name the Thick-Billed Murre can be found at 211m, while Wikipedia will only admit to 150m, so I’m uncertain as to its accuracy.
This did spark in me a question as to analogous situations, in the sense that, at least in me, the idea of going down deep into the ocean in a mere scuba suit leaves me with a sense of apprehension, even if the problems of pressure and nitrogen narcosis were solved – I dislike the thought of some hungry predator taking a chunk out of me. But any similar situations?
Caving, perhaps, although caves are not known for their predators.
But how about a hypothetical species based outside of an atmosphere? It is not unreasonable to suggest such a creature might have eyes sensitive to the electromagnetic spectrum that is filtered out by our upper atmosphere. Might they look at a planet like Earth as a dark and foreboding hole in space, possibly populated by similarly predatory creatures that create unease in me?
