This has 144 images you are welcome to use however you want. There are color photos and black and white drawings. Insofar as instructions or suggestions go, you can enlarge or shrink the public domain images’ sizes, move the images around, etc. The images are handy for any classroom (Pre-K through higher ed) 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.
Sources for the clip art here and in other publications include wpclipart.com, clker.com, wikipedia.org, plates from the 1800s works of John Gould, John James Audubon, various federal government agencies, and a few from myself.
This is dedicated to my wife Barbara, a sincere, caring science teacher for 28 years.

P.S. In my store is public domain clip art for many other animals as well.
