About a dozen kinds of Horned "Toads" are found in the western portions of the United States. Although toad-like in the shape of their bodies and in some of their habits, they are really lizards.
The American Chameleon or "Green" Lizard, which ranges in this country in the coastal regions from North Carolina to the Rio Grande River, has a remarkable power of changing the color of its skin through shades of brown, gray, and green. In fact, it is said to rival or possibly excel the true chameleons of the Old World.

FISHES
"It is not all of fishing to fish."
PADDLE-FISH
So-called from the paddle-like or spoon-shaped snout. Eggs used for caviar. Range: The Mississippi River and its tributaries.
The fishes are the lowest of the true vertebrates or animals with backbones, and all live in the water. They do not have lungs, but breathe through gills on the sides of the head. They are cold-blooded animals; i. e., the temperature of the blood is the same as that of the water in which they are living. Fishes are found in both fresh and salt water all over the world and have adapted themselves to many conditions; for example, certain fishes have lived in caves so long that they are blind; some live in the coldest water, while others can revel in the heat of the hot springs.
COMMON CATFISH
The barbels which suggest the whiskers of a cat are responsible for the name. This fish has no scales. Range: Eastern and Central United States.
