Select Source

Eight legs, three hearts, and a wealth of suction cups - the octopus is one of nature's most curious creations. Color-blind, it still can mimic multicolored backgrounds, and even use color to communicate. Shy and retiring, these cephalopods are hard to find and study, but Ultimate Guide: Octopus reveals their secrets, with amazing, up-close footage of a creature that prefers not to be seen.
