Description
The hellbender is a giant salamander endemic to the eastern and central United States. A predatory lifestyle in fast, shallow streams has resulted in many adaptations that give it its strange looks - the flat body with a large head, skinfolds for breathing, and tiny eyes assisted by light-sensitive cells in the skin. Very sensitive to pollution, the hellbender is currently listed as "near threatened."
