The octopus is a very intelligent animal, possibly more intelligent than any other mollusk. The intelligence and learning ability of octopus are still being debated by biologists, labyrinth experiments and problem solving have shown that octopus has memory systems, including short and long term memory. It is not yet clear how learning contributes to the behavior of adult octopus. Baby octopus learn little from their parents’ behavior, and they also have very little connection with their parents.
Octopus has a complex nervous system. 2/3 of a neuron is in the nerves in its tendons. Octopus tendons have complex reflexes with control over at least three levels of the nervous system. Some octopus, like the Mimic octopus, move their tentacles like other sea creatures.
