[Span, el legarto, the lizard.] A large American reptile of the Crocodile family. It has a shorter and broader snout than the crocodile, and the large teeth of the lower jaw fit into pits in the edge of the upper jaw, which has no notches. Alligators vary in length from 2 to 20 feet, the head being about one-seventh of the entire length. They embrace three genera, the alligator, abundant in Florida, and the caiman and jacare, found in tropical South America. The caiman is also found in Mexico. Their principal food is fish, but they catch and devour land animals, as the sheep and pig, and sometimes even men. An alligator lays from 50 to 60 large eggs in a hollow in the mud, covered over with grass and reeds, and leaves them to be hatched by the sun. The young take to the water as soon as hatched, being carefully tended by the mother alligator. The skin when tanned makes good leather for boots and shoes.
