rivendellroseThe veined octopus in Australia is added to the ongoing list of animals known to use tools.
Not only use, I would add - modify and carry around with them for future use. The shells are useless to them until they've cleaned out the silt and other muck that the shells accumulate, and then they have to carry the shell around until they need it - it's no good if they see a predator and then look for a shell. So that's a degree of planning ahead as well.
