A freshwater Crocodile!!!
“Crocodile tears” is a common expression which is used for depicting fake sadness. It has its origins in the myth according to which crocodiles weep while eating their prey. Of course, there is no “eater’s remorse” involved when a croc turns on the water works.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.
