Scientists have discovered an octopus that collects coconut shells and makes a shelter out of them. Octopuses use foreign objects as a shelter but in this case, the octopus prepared the shelves by emptying them out, carried them for some distance and reassembled them to make a spherical hiding place. This seems to be the first example of tool use in an invertebrate animal. Isn't that amazing? What do you think?
