Crawling movement of an octopus

research As mentioned in the TED talk, the nervous system of an octopus is spread throughout the body, and about 70% of nerve cells are in the eight arms. Each arm can move independently by the information processing of the peripheral nervous system. Furthermore, by exchanging information among the peripheral nervous system and the central nervous system, the octopus can coordinate the arm movements and realize swimming and crawling.
