Imagine if your job was to catch reptiles and make them throw up! That’s part of what Brady Barr does when he goes out in the field. Barr is a herpetologist, a scientist who studies reptiles and amphibians. On one expedition Barr flew to Cuba to find out what rare Cuban crocodiles eat.
To examine the crocodiles’ diet, Barr must make the animals empty their stomachs by vomiting. Then he pokes through the contents that come out. Not exactly glamorous, but it is one way that herpetologists study these creatures to learn how they live—and what they eat—in their natural habitats. Check out a video showing Brady Barr in action.
