Must have been brackish water. We would see them in the Loxahatchee allot when I was a kid.

Isn't the Atachfalaya the deepest river in the world? I think the Mississipi runs into it because it's so deep.

The Red River is NOT brackish water. Anywhere. its a couple hundred miles from the coast!

The Bull Shark has a high tolerance for fresh water. They retain the ability to move into rivers as adults.

I saw a big one, 7 or 8 feet long, while scuba diving down in Mexico back in January. You expect to see sharks in certain waters, but this is one of the species that makes you sit up & take notice.
