Question

Quizplus · Accepted Answer

Sea stars have a nerve net in each arm, which allows for decentralized nervous control and little integration of signals. However, they do not have a single ganglion in each arm. Instead, sea stars have a centralized nerve ring in the center of their body from which the nerve nets in each arm radiate.
