Not trying to bust your chops 'cause I wasn't there and I'm not bringing a tape with me, but:
Myth: Alligators can grow to enormous proportions, over 20 feet in length and weighing a ton or more.
Fact: The longest recorded length for an alligator is 19' 2'. This animal was trapped in the early 1900's in the State of Louisiana. Most wild alligators do not get above 13 feet in length, and may weigh 600 pounds or more.
And another source:
A record length for the alligator species, recorded during the 19th century, measured 19 feet; however, today's big males rarely reach 14 feet.
Hmmm....makes me wonder what else you might think is bigger than it actually is
