Why is This Crocodile Coughing?

A Florida crocodile was captured "coughing" at a photographer at Everglades National Park, recently published video shows. Wildlife photographer Kymberly Clark recorded footage from her car of the crocodile's frightening cough-like display, which it repeated a number of times. Clark shared the video to Instagram and joked that the crocodile "didn't want her photo taken by paparazzi." "American crocodiles are typically quite docile but I suspect this one is a female with a nest or was warning me she had babies close by," Clark said. According to the University of Georgia, American crocodiles use a wide variety of sounds for effective short-distance communication. These include hisses, coughs, grunts, moos, and toots.
