Compare two species

Webster's Salamander vs. Southern Red-backed Salamander

The two share rocky hardwood slopes in Alabama and Georgia (five one-degree squares, all with several records of both); in Louisiana Webster's lives only in the Tunica Hills. A: Heavily mottled with yellow, white and dark grey flecks: a lighter, yellowish underside in the Webster's Salamander; dark grey to black, densely peppered with fine white specks: a much darker underside in the Southern Red-backed Salamander. B: Straight-edged, wavy or irregularly lobed; rarely sharp, even teeth in the Webster's Salamander; sharply saw-toothed, one even tooth at each rib groove in the Southern Red-backed Salamander. C: Red or orange from the stripe often runs onto the bases of the front and hind legs in the Webster's Salamander; the red stays on the back and tail, rarely onto the legs in the Southern Red-backed Salamander. Both have plain grey forms; the belly and the stripe edge still tell them apart.
