Sleep is for the weak...and sharks?

Think naps are for babies? Think again.

Sharks have inspired countless terrifying movies and the 2016 thriller "The Shallows" is a testament to the fact that it's still one of the more frightening creatures in land or in more moist places.

But, strong a predator as sharks may be, they still need to get some shuteye.

For the first time in recorded history, Shark Week 2016 footage from the Discovery Channel shows a great white shark (named "Emma") in "an almost catatonic state."

This new information reveals that Bruce the Shark and Dory from Finding Nemo have something in common: They both need to keep swimming.

"Facing into the current, with her mouth open, oxygen-rich water flows over Emma's gills," a man narrates. "It allows her to slow down and save energy for hunting during the day. But she can never stop swimming completely or she'll sink to the bottom, suffocate, and die."

Discovery has previously clarified that it is not entirely true that sharks need to be in constant motion or they would drown—but it's a little similar to holding one's breath underwater for a few seconds.

In any case, if you feel bad for needing to close your eyes for a bit, just remember: Napping is something even the best hunters do. —Aya Tantiangco/KG, GMA News
