Amphioctopus marginatus

Amphioctopus marginatus, also known as the coconut octopus and veined octopus, is a medium-sized cephalopod found in the tropical waters of the western Pacific Ocean and the Indian Ocean. It prefers sandy substrates with plentiful shells or litter. It commonly preys upon shrimp, crabs, and clams, and displays unusual behavior for octopuses, being one of only two species known to exhibit bipedal walking. The coconut octopus is also known for collecting and using tools; it gathers coconut shells and seashells and uses these for shelter.
