For 219 alligators captured in four Florida lakes, researchers classified the primary food choice (in volume) found in the alligator’s stomach in one of the categories—fish, invertebrate (snails, insects, crayfish), reptile

(turtles, baby alligators), bird, or other (amphibian, mammal, plants). (Data available on the book’s website.)
