With lanky limbs and a rounded head, an octopus can change color depending on its environment.

Found a couple hundred feet below the surface, the giant octopus usually weighs about thirty pounds and has a span of fourteen feet but can be much larger! Its head, or mantle, contains many vital organs, including three hearts. The skin that stretches across the tentacles and the mantle is fairly smooth and equipped with chromatophores, pigments that can grow or shrink in order to help the octopus camouflage. Some of the predators that prey on octopus are whales, otters, and seals. Tricks that an intelligent octopus may employ to distract their predators are to discharge ink or to remove one of its tentacles which will continue to move for a bit after removal. Known to not be above having shark for dinner, an octopus will eat clams, fish, shrimp, crabs, and scallops thanks to help from its venom.
