Just when you thought octopuses couldn’t get any weirder: It turns out that their suckers have an unexpectedly hairy grip. Octopuses can form an impressively tight grip—even on a rough surface.

Most octopuses get around primarily by crawling along the seafloor. And if they need to get somewhere in a hurry, they can employ their funnels to jet away like their pelagic cousins, squid.
