The hellbender is one of the largest salamanders in North America. It's also one of the most unmistakable, with its flattened head, body, and tail, and loose, wrinkled flaps of skin along its sides. Hellbenders are found in clear, fast-flowing rivers and streams. By day, they hide under rocks and debris. At night, they come out to look for food.
