Is a Medusa nervous system more complex than a polyp?

Yes, a Medusa has a more complex nervous system than a polyp. Medusae, which are the free-swimming life stage of jellyfish, possess a nerve net that allows for more coordinated movement and responses to stimuli. In contrast, polyps, which are typically sessile, have a simpler nerve net that supports their stationary lifestyle. This complexity in Medusae enables better swimming and prey capture behaviors compared to polyps.
