I was the Dive Master on that expedition and am proud to say that I am the first person to have touched one of them - since thhe Civil War.

In answer to your questions, We didn't encounter any Snapping Turtles, however I have seen some MIGHTY BIG ones in the Tensas Swamp around there.

What we did encounter were a lot of Alligators and over my decades of working diving around here - I have encountered quite a few.
