I wish i had a photo of the 19' gator on display at our(Louisiana) Dept. Natural Resources. It actually defies logic it is so big.
Did find a picture of a much smaller, but still big, 13' gator.

Here is a picture of a 12-13 foot gator swimming with a deer in his mouth. Size was estimated, as no one went down to measure him.
