Mar 09, 2022

Sleeping sharks, with their eyes open sometimes, were discovered by scientists. The discovery adds to the unique notion that shark sleep is different than other mammals as previously thought. Nevertheless, sleep for sharks and other fish has the same purpose of energy conservation just like for mammals.

The study also confirmed from previous anecdotal evidence and research that sharks do also sleep at all. The study contradicts previous rumors that sharks do not sleep at all. In the new discovery, shark sleep was seen as a biological necessity, meaning they all sleep like other animals to sustain body functions.
