This is a youth book, published by Scholastic. We unearthed a lot of books from my dad's storage building this summer and this was one of them. Of course, some of the information is outdated (as it was published in 1973), but I think the reason we held on to it was because Ross Allen's Reptile Institute and Silver Springs, Florida, figure prominently in it. My dad worked for Ross Allen during his younger years, and Dad was a big fan of alligators and other reptiles. I will likely release this book, but it was a fun read. It focused primarily on American alligators but touched on American crocodiles, Nile crocodiles, caimans, and gharials as well. ( )
