IFLS wrote New Study Confirms Ancient Legend About Crocodiles

Essentially, scientists found that crocodiles can remain on watch even while they’re sleeping.

…they are able to undergo what’s known as unihemispheric sleep, where only one side of their brain shuts down for sleep at a time, while the other half remains active. Not only that, but they apparently do so while keeping one eye open to watch out for potential predators… or prey.

People always ask writers, “Where do you get your ideas?” The answer? Everywhere. Especially after reading an article like this. The animal kingdom is full of strange, cool, and sometimes terrifying abilities like this. The trick is farming and combining the bits and pieces into something new to present to the readership.

But seriously, how badass is this? It turns out that a bunch of animals can do this, including marine mammals like dolphins and sea lions. Dolphins can actually continue swimming while sleeping.
