Coconut Octopus

Amphioctopus marginatus
The Coconut Octopus is a rather unusual Cephalopod, in fact, they are one of only two different Octopus species that has been observed walked in a bipedal nature. Furthermore, depending on how you look at it, they actually use tools!

The tropical waters of the western Pacific Ocean is where there creatures call home, dwelling in areas where there is a sandy bottomed floor. They aren't especially large-- their heads are about 3in long, while the tentacles measure an additional 6. They feed on small Crustaceans and Clams.

Coconut Octopuses get their name from the fact that they use coconut shells for protection and shelter. They pick up discarded half shells and carry them around their soft bodies. When threatened, they can cover themselves with the shells, creating a permanent hiding place. There are many scientists who argue that this constitutes tool usage, while there are a handful that dispute the claim.
