These eight-armed invertebrates are pretty smart. They also have fairly large brains, and like humans, their brains are separated into folded lobes. Octopus’s use a specific part of their brain for visual recognition which is unusual for many animals. These cephalopods enjoy playing and problem solving, they will use tools,
and they also try to avoid boredom if possible and exhibit a fairly impressive short term memory. Scientists have seen these creatures solve puzzles and mazes. Most amazingly, we still don’t know that much about them. Scientific research is constantly discovering new things about these amazing sea nerds.
