Catahoula Spotted Dusky Salamander vs. Southern Red-backed Salamander

Both live in the hill country of central Louisiana (the Kisatchie Hills), under logs near seeps and small streams. A: A pale line from the eye back to the angle of the jaw in the Catahoula Spotted Dusky Salamander; no pale line from the eye to the jaw; a red to brown stripe with saw-toothed edges down the back in the Southern Red-backed Salamander. B: Hind legs much stouter than the front legs in the Catahoula Spotted Dusky Salamander; slim legs, the hind and front about the same size in the Southern Red-backed Salamander. Dusky salamanders live at the water's edge and jump when disturbed; red-backed salamanders live under logs in moist woods.
