How do jellyfish sleep?

2 Answers
ANSWER

Jellyfish sleep basically the same way you do. They enter a state where they stop moving around. Their reflexes are slowed so they don't respond to stimuli and they no longer interact with the environment while they are asleep.

The jellyfish are 30 percent less active at night. They pulse less frequently, and they go through several pauses, 10 to 20 seconds long, where they stop pulsing altogether.
