These monsters can roam in freshwater and saltwater (at least for a bit) looking for something or someone to snack on. Not only dangerous in the water, but on the bank as well. Gators are known to create burrows up to 20 feet deep in the mud. A nighttime stroll might find you in a pit face to face with the beast.
Bull sharks are not limited to saltwater. Due to the shark’s impressive adaptation, it can swim in freshwater. They have been known to swim up the Mississippi as far as Minnesota. They prefer shallow coastal water, which means they often come into contact with humans.

Snapping turtles live in shallow, fresh water and their habitat range stretches from Southern Alberta and east to Nova Scotia in Canada and extends south to the Gulf of Mexico and into central Texas.
