The coconut octopus or veined octopus (Amphioctopus marginatus) is one of our favorite critters in Lembeh. It uses “tools” like shells and coconuts to build a hiding place and is often seen ‘walking’ on two arms with these tools in the other arms. This behavior is called bipedal locomotion. Some species are very greedy and try to take as many tools as they can carry, which sometimes is just too much to handle. The coconut octopus is a solitary cephalopod.
