About Fishes in Missouri

Missouri has more than 200 kinds of fish, more than are found in most neighboring states. Fishes live in water, breathe with gills, and have fins instead of legs. Most are covered with scales. Most fish in Missouri “look” like fish and could never be confused with anything else. True, lampreys and eels have snakelike bodies — but they also have fins and smooth, slimy skin, which snakes do not.
