Asta loves exploring and studying the exciting world under the sea. Each week, she will attempt to learn and answer her reader's most burning marine science questions, and provide some resources that help turn the question into a lesson plan!
This weeks question comes from Ilan, age 5:
"Do fish sleep? How?"
Fish may not curl up in a comfy bed like humans do, but they still make time for rest and refreshment. They can't get any shuteye though because fish don't have eyelids!
There are still plenty of unanswered questions about fish sleep. Fish all seem to sleep slightly differently.
Maybe this would be a cool subject to research as a biologist! What do you think this knowledge could be useful for?
