The alligator snapping turtle is the largest freshwater turtle in the U.S.. They can grow to 175 pounds. It is identified by the three horny ridges down its shell. They spend most of their time in the water and can remain submerged for 45 minutes. They eat any fish, frogs, snakes, snails, worms, clams, crayfish, aquatic plants, and other turtles; they catch some of these by lying at the pond bottom and waving a lure-like structure in its mouth that retracts into its jaws when the prey bites at it.
Brown bullhead catfish grow to about 14 inches long, weigh about one pound, and live about 3 to 5 years. They live in shallow bays, near the soft bottom among vegetation. They eat algae, plants, mollusks, insects, fish eggs and fish.
