>I'd bet dolphins, seals, and the like have a lot more sensors/cm2 of skin than humans, and probably other important sensing as well that we don't need. That's interesting. For what reason should we presume sensors/cm2 is higher in aquatic than terrestrial species? Is sensation of flow across the skin very important to them? I was thinking about this myself and presumed the opposite, that proprioception is important but feeling each portion of the skin isnt so important, after all sensation across the skin for a swimming animal would be unending, like tinnitus for a man. Good thinking and glad we could connect.
