Coconut Octopus

Coconut Octopus Hiding in Shells The coconut octopus is one of the few invertebrate species documented to use tools. They don’t just hide in shells; they collect and carry them, demonstrating complex planning and high cognitive function. They often select two halves of a clam or coconut shell, positioning one underneath them and holding the other above. When a predator approaches, they pull the two halves together, creating a nearly impenetrable, rolling shelter they can deploy instantly. Filmed
