 Chimps do it. Dolphins do it. Even crows that want to catch fish do it. But an octopus1? Yes, it seems the smartest member of the invertebrate2 world has learned how to use a tool. Octopuses3 have a reputation for being clever. They can figure out how to pull a plug out of a glass jar to get to food. They have been known to escape from holding tanks. They have the ability to navigate4 mazes5 and seem to be able to remember past experience. But tool use? That does seem incredible. Tools, by definition, are objects that have no purpose until they are used for a specific function. Scientists have known for some time that octopuses make use of shells and other objects they find to hide from predators6. But observations of veined octopuses, known as Amphioctopus marginatus, off the coast of Indonesia surprised scientists. Not only do they use coconut7 shells to hide beneath, they carry the shells with them.
