Octopuses off the coast of Indonesia have become media sensations as a result of their remarkable talents recently captured on film. The sea creatures are seen collecting coconut shells, transporting them over great distances, and then using them as shelter on the ocean floor. While finding refuge in a shell is not particularly new behavior from an octopus, the intentional collection of such objects for future use constitutes the first instance of an invertebrate species using tools. More on the story, including video of the octopuses in action, here.
