Veined octopuses hide in discarded coconut shells, scientists in Indonesia discovered. An octopus may even carry multiple shells for future use, stacking them like bowls, spreading its arms around the shells and "stilt-walking" with the shells wedged within its eight arms. Hermit crabs use seashells for shelter, but because these octopuses carry their shells for later use, they are the first invertebrates known to use tools.
