Scientists recently discovered that the veined octopus is a tool user. The tool? A coconut shell. The use? Shelter.
The researchers watched octopuses off the coasts of Northern Sulawesi and Bali dig for coconut shells in the mud, clean the shell, then lift the shell and run away with it. When the octopus is ready to hunker down, it flips the shell over and climbs underneath. If an octopus finds two halves of a coconut shell, it climbs into one half and then pulls the other half over itself.
