What is the largest alligator reported.?

During a study done in Florida from 1977 to 1993, the largest male alligator reported was 14 feet long, and the largest female was 10 feet, 2 inches. An alligator that was killed and left in a Louisiana marsh in the early 1900s was estimated to be over 19 feet long. However, the record has long been disputed, and the largest size verified for an alligator from anywhere, based on a statistical ysis of skulls, skins, and live animals, was slightly under 15 feet.
