Hellbenders
Hellbenders are large, aquatic salamanders found in North America. They have flat bodies, wrinkled skin, and a wide head with small eyes and a broad mouth. Hellbenders are typically brown or gray in color and can grow up to 29 inches in length. They are primarily nocturnal and feed on crayfish, insects, and small fish. Hellbenders are known for their ability to breathe through their skin, absorbing oxygen from the water as it flows over their bodies. These unique amphibians are considered indicators of water quality, as they are sensitive to pollution and habitat degradation.
