Cephalopods (octopuses and squids) are mollusks that live in seas all over the world.

Cephalopods Have Large Nervous Systems - in Their Arms

They are currently considered the most intelligent mollusks in the world. Cephalopods have both a short-term and long-term memory. This is especially impressive considering their nervous systems aren’t in their brains, but in their arms.

Chephalopods Use Tools and Think About the Future

Cephalopods in Indonesia have been seen using coconut shells to protect themselves from enemies. The coconut octopus gathers coconut halves from the sea floor and uses them to create a protective little cave.

Octopuses don’t usually live in caves, they only seek them out for protection. This means that the octopuses plan for the future e.g. to be prepared for possible danger.
