Hi, my name is Brady Barr, and I’m a zoologist. That means I study animals. I’ve studied all kinds of animals in about 70 countries on Earth. But of all the animals I’ve worked with, crocodiles are my favorite.
There are 23 different types, or species, of crocodilians (sounds like krah-koh-DIL-ee-uhns). I’ve had the chance to see them all in the wild. I’ve been up close to the wide-snouted alligators and caimans (sounds like KAY-mens). I’ve been nose-to-nose with the narrow-jawed crocodiles. And I’ve even studied the weird and wonderful gharial (sounds like GAR-ree-uhl).
Sometimes I have to catch wild crocodiles for my work. For some studies, my team and I need to weigh and measure crocs. For other studies, we need to attach high-tech devices to the crocs. These devices help us keep track of the crocs, or they record information about changes in the areas where the crocs live.
The number of people on Earth is growing every year. More humans on the planet means people need more space. People are moving into areas that were once the wild homes, or habitats, of crocs. With their habitats shrinking, many species of crocodilians are dying out. When a species is dying out, we say it is an endangered species.
