How big do alligators grow?

Growth rates may vary from 2″ up to 12″ per year, depending on the type of habitat in which the alligator is living and the sex, size, and age of the alligator. Growth rates slow down as alligators become older. Male alligators will grow faster and larger than females. Males can grow to approximately 13’+ in length and attain 500+ pounds. Females can grow to approximately 9′ in length and 200+ pounds.
