Crocodiles Really Shed Tears While Eating

Crocodile tearsFor centuries insincere humans have been said to cry crocodile tears—a nod to the famous tale that crocs weep with false remorse while devouring their prey.

Now research has shown that some reptiles really do shed tears during a meal, but most likely for biological rather than emotional reasons.

"Generally crocodile tears are pretty similar to human tears," said study co-author Kent Vliet of the University of Florida. "You see moisture in their eyes or collecting in the corners of the eyes. At times it will drip out of the corner and run down their face just like you'd expect a tear to run down a child's face."

"Crocodiles appear to produce tears all the time," said croc expert Adam Britton, founder of the informational Web site

"Their function is—like our own tears—to lubricate the eye. This may be even more relevant for crocodiles because they have a third eyelid," also known as a nictitating membrane.
