Stupid octopus tricks

Well, since I'm not the only one feeling the cephalopod love, here's one more for you. As was noted, octopuses are notorious for escaping from tanks since they are agile, clever and have no rigid skeleton - allowing them to squeeze through practically any gap that they can squeeze their brain through.

This is actually more than just a stupid pet trick since it really helps to remind you that, in water at least, a hydrostatic skeleton, like that of an octopus, can be very impressive and allow sophisticated, rapid and powerful movement.
