Do jellyfish sleep?

Worms and fish do it. Birds and bees do it. But do jellyfish fall asleep?

It was after midnight A__________where the jellyfish were kept. They left the lights off and walked through the room by the glow of their cellphones. The students did not tell anyone that they were doing this. The secret they were keeping was a “totally crazy” experiment aimed at finding out whether jellyfish sleep.

It turned out that the jellyfish moved about 30 percent less at night. It was also harder to get their attention.

The results suggest F__________life, as the jellyfish group of animals first arose about 700 million years ago, and has stuck with us ever since.
