ALLIGATORS, CROCODILES AND CAYMANS PUBLIC DOMAIN CLIP ART (over 42 images) has the following.
There are over 70 public domain images of alligators, crocodiles, and caimans (alternatively spelled caymans). Most are color photos but a few are black and white drawings. Most are realistic but some are comical caricatures.
You can enlarge or shrink the public domain images’ sizes, move them around, etc. The images are handy for any classroom and any age or ability level but teachers of art and natural studies in science will likely regard them as being of special interest.
Teachers of Pre-K students up will find them handy for using as reward stickers, for classroom décor, etc.
