protection
A research team led by Julian Finn of the Museum of Victoria in Melbourne has discovered octopuses using coconut shells as portable protection. Not only do they hide under single halves but will actually pull two halves together and hide inside, like some sort of Super Mario baddie. The video is remarkable.
Using tools means octopuses now join an elite club of wise animals including chimps, dolphins, and Tim Allen.
