Question

Write five sentences about the functions of an jellyfish nervous system

Answer 1

A jellyfish's nervous system is a diffuse nerve net that coordinates muscle contractions to produce the rhythmic pulsing used for swimming. Specialized structures called rhopalia contain pacemaker neurons and simple sensory organs that regulate that rhythm and detect light and gravity. The nerve net transmits touch and chemical signals to trigger tentacle movements and nematocyst discharge for prey capture and defense. Lacking a centralized brain, jellyfish process information locally so different body regions can respond independently to stimuli. The system also supports simple reflexes and a high capacity for regeneration, allowing jellyfish to maintain essential behaviors after injury.
