Is there any animal that doesn't sleep?
My science teacher gave us a fun fact challenge and I'm really curious. Are there any animals in the world that literally never sleep? Sounds impossible, but I wanted to check!

Hey! Don't stress too much about late-night trivia, but yes, bullfrogs actually don't sleep in the way we do. They stay alert even while resting, which is pretty crazy if you think about it!

Practically speaking, animals like dolphins and sharks can't fully sleep because they need to keep moving to survive. They just shut down one half of their brain at a time. It is a very efficient system.

If you are asking because you are having severe sleep issues, please don't compare yourself to marine animals. Go see a sleep specialist or general physician instead of staying up reading biology facts.

Look, jellyfish don't have a brain, so technically they don't sleep like us. But every living being needs some resting period to function properly, so make sure you are getting your 8 hours too.

I read that newborn killer whales and dolphins don't sleep at all for the first month of their lives. Honestly, sounds like me during engineering exam season!
