Everything you ever wondered about the American alligator is now in one book, Robb said.
"Being able to put good information out about an animal that doesn't get a lot of good information and that really need a voice with a book like this and being able to talk about this on a public scale, it's amazing," he said. "I hope that it's making a difference."
"I'm trying to give really these animals a voice that they haven't ever had," Robb said.
