Wildlife: American Alligator, 1 by Thaumaturgist

It was sunning in the backyard of a home on the shores of Lake Rowena, Orlando, Florida. As I cautiously
and slowly attempted to approach, it retreated into the lake almost immediately.

About 2 hours later, I found it by accident on a shallow section on another part of the lake. Unfortunately this is
the closest shot that I could have.

From hundreds of Alligators in this lake, how could I be so definite that this was the same one I had been looking
for?

The front left leg is missing.

Victim of a possible territorial struggle. Photo taken in March.
