Do starfish sleep?

Best Answers

Starfish don’t have “true brains,” just the functional equivalent of brains, i.e., a ring nerve with concentrated bundles of neurons attached. On the other hand, insects have far more neurons in their brains, from 100,000 to 3 million, and only some insects sleep. Many do not. So it could go either way. read more

They do not sleep. The long answer depends on the species of starfish you are looking at. There are different body types of starfish, each with a unique behavioral mechanism and life history. read more
