Flat body with loose skin folds, very flat broad head with a short snout, no eyelids, small stubby limbs and webbed toes (four front, five hind); muscular tail. [1][2]
Deep brown or black, occasionally with dark orange spots above or below; belly lighter; sexes look alike; rare albino and red variants. [1][2]
Larvae are 25-33 mm and limbless at hatching and have pale gill slits, lost at maturity. [1][2]
Where it lives
Clear, rocky, fast-flowing creeks and rivers with large shelter rocks and steady oxygen and flow, usually where water stays below about 20 C; avoids wide, slow, muddy water. [1][2]
How it behaves
Nocturnal and solitary; hides by day under large flat rocks at the stream bottom and hunts from dusk to dawn, with territory centred on the shelter rock (average about 113 m2) defended against other hellbenders. [1][2]
