octopi are pretty sweet, i saw a video of one walking on two of its tentacles with the rest arranged to look like algae, so it looked like moving algae. i also saw another where an octopus flattened its body to look like a snake, then swam like a snake too. plus that shark vs. octopus video i saw here earlier today. they're supposedly very intelligent, and can be trained to do all sorts of things like change color essentially on command. (well, change color in order to be fed)
