. While crocodiles do have tear ducts, they weep to lubricate their eyes, typically when they have been out of water for a long time and their eyes begin to dry out. However, evidence suggests this could also be triggered by feeding. Bogorad's syndrome, a condition which causes sufferers to shed tears while consuming food, has been labelled "crocodile tears syndrome" in reference to the legend.

While crocodiles can and do generate tears, the tears are not linked to emotion. The fluid from their tear ducts functions to clean and lubricate the eye, and is most prominent and visible when crocodiles have been on dry land for a while. In the case of

, the tears help rid of the excess salt that they take in with their food. According to Adam Britton,

It is difficult to trace the origin of this particular myth, but it's easy to see why it has become so popular – for an apparently remorseless creature such as a crocodile to actually weep over its victims is a memorable irony which has inspired considerable prose and created a phrase which is still popular today.

In 2006, neurologist Malcolm Shaner, assisted by Kent Vliet, a researcher at the University of Florida, decided to test the story that crocodiles or their close relatives alligators and caimans were likely to "weep" while feeding. Studying animals in Florida's St. Augustine Alligator Farm Zoological Park, Vliet recorded seven caimans feeding. He chose to use caimans rather than crocodiles because at the sanctuary they could be observed feeding on dry land. Five of the seven animals were seen "weeping", leading to the conclusion that the story describes a real phenomenon. The researchers suggest that the "weeping" may be caused by the hissing of warm air during feeding, which is forced through the sinuses, stimulating the animals' tear glands into emptying fluid into the eye.
