Coconut Octopus

Amphioctopus marginatus, also known as the coconut octopus or veined octopus, is a medium-sized cephalopod found in the tropical waters of the western Pacific and Indian Oceans, preferring sandy substrates with plentiful shells or litter and commonly preying on shrimp, crabs and clams. It displays unusual behavior for an octopus, being one of only two species known to walk bipedally, and is known for gathering coconut shells and seashells to use as shelter, a form of tool use.
