UNDERCOVER CROC
Thats me, zoologist Brady Barr, dressed in a special crocodile suit. My disguise let me get close to the crocs and collect information.
My team and I are ready for our dangerous mission in Tanzania.
Chapter 1
Croc DISGUISE
Hi, my name is Brady Barr, and Im a zoologist. That means I study animals. Ive studied all kinds of animals in about 70 countries on Earth. But of all the animals Ive worked with, crocodiles are my favorite.
There are 23 different types, or species, of crocodilians (sounds like krah-koh-DIL-ee-uhns). Ive had the chance to see them all in the wild. Ive been up close to the wide-snouted alligators and caimans (sounds like KAY-mens). Ive been nose-to-nose with the narrow-jawed crocodiles. And Ive 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.
The more we know about endangered species and what they need, the better we can help them. But catching wild crocs is a dangerous jobfor me and for the crocs!
To catch a croc, I usually have to snare it with a rope. Then I wrestle it until it is very tired. I jump onto its back and tie its jaws shut so it cant bite. Then I tie its legs. Thats a lot easier said than done!
Even a tired crocodile is very strong. Catching one can turn dangerous quickly. Crocodiles are not used to having people jump on their backs. It is strange for them.
Endangered Crocs
About one-third of all croc species are endangered. In fact, many are among the most endangered animals on the planet. The Philippine crocodile used to live in lakes and rivers throughout the Philippines (sounds like FILL-ih-peens). Today it is only found in a few areas. As the number of humans has grown, more and more of its wild habitat has been turned into farmland.
Loss of habitat has driven the Philippine crocodile almost to extinction. Once a species is extinct, its gone forever.
Thats why I am always looking for better ways to handle the crocs and get the information we need.
We know that crocodiles are calmer around other crocs than around humans. If only another croc could find out what we need to know. Then it wouldnt be so hard on the animal we want to study.
