They have some incredibly advanced biotechnology on them especially when you think about their sophisticated chameleonic skin color changing response, camera-like eyes, and extremely flexible bodies. Considering these are all invertebrates, they have a very large nervous systems as well.
These highly developed brains are considered to be extremely intelligent and they have been able to prove their skills by solving complex puzzles. Just check out this video of an octopus opening up a jar!
