Octopuses have a super-advanced nervous system for an invertebrate. They have a main brain and eight large ganglia in each tentacle, which can make decisions on their own. It's not like the human central nervous system, but it's the closest thing in the invertebrate world.

The crab has a simpler nervous system than the octopus. Instead of a complex brain, it has a cerebral ganglion and a ventral nerve chain.

Spiders have a compact brain and a ganglion chain, which allows them to coordinate those hairy legs with precision. Their nervous system is adapted for hunting and stealth.
