Crocodile Tears - do crocodiles really cry?

We use another popular expression stemming from the animal world when faced with an insincere emotional display of sorrow. It was believed that crocodiles tend to shed tears while devouring their prey, thinking it was ironic to weep for your victim while eating it. But do crocodiles really cry? You may be surprised to know that these dangerous animals do produce tears, though not as an emotional reaction. Tearing up is actually a way to clean or lubricate crocodile’s eyes, most commonly observed after they’ve spend a while on dry land. In some instances “crying” was observed while feeding as well, but rather than grieving for the croc’s pray, tears were caused by warm air being forced through the animal’s sinuses.
