How does a crabs nervous system work?

A crab's nervous system is decentralized and primarily consists of a ventral nerve cord with ganglia that control various body segments. Sensory organs, such as compound eyes and chemoreceptors, send information to the central nervous system, which processes it and coordinates responses. This system allows crabs to react quickly to environmental stimuli, aiding in survival and movement. Overall, their nervous system is adapted for their aquatic habitat and predatory lifestyle.
