Sea octopuses do have a nervous system, but it's quite different from that of humans. Their nervous system is organized in a way that allows each arm to have a degree of autonomy, even when separated from the main body, according to the University of Chicago article.

Ants do have a nervous system. Similar to humans and other animals, they have a central nervous system (CNS) with a brain and nerve cord, and a peripheral nervous system (PNS) with nerves that connect organs, limbs, and sensory receptors to the CNS.
