Let us first understand what the term 'sleep' means. According to the Merriam-Webster dictionary, sleep is, 'the natural periodic suspension of consciousness during which the powers of the body are restored.'
In simple terms, it is a state of utter relaxation, where there is a temporary cessation of thoughts and ideas, and the strength of the body gets restored. Does the sleep of fish fit this definition? Or do they sleep some other way?
Some fish are seen floating at a particular place, while others take shelter in a particular spot, like the mud or corals. Some even build a nest for resting. These fish remain alert for any sign of danger, but at the same time, are able to rest peacefully. Here are some more interesting facts on the sleeping habits of different animals.
