Have you ever wondered why the Octopus never gets itself all tangled and stuck together? It’s something that has bothered me for most of my life. Actually it’s never bothered me, I just added that last line for dramatic effect. Anyway the reason is that one of the few things that the suckers on an Octopus tentacle don’t stick to is Octopus skin! Is it the same for a squid? Does anyone know? Does anyone care? Anyway to read the story about how sticky a tentacle sucker is click here. The whole experiment comes across as a little gory as it reveals that amputated tentacles can survive for up to an hour after being cut off! That’s like the undersea equivalent of the headless chicken isn’t it?
