Compare two species

Sequoia Slender Salamander vs. Relictual Slender Salamander

Their ranges do not meet: the Kaweah River drainage (Sequoia) vs Breckenridge Mountain, Kern County (Relictual). A: Longer legs in the Sequoia Slender Salamander; shorter legs in the Relictual Slender Salamander. B: Longer: 19 or 20 trunk vertebrae (18 to 20 costal grooves) in the Sequoia Slender Salamander; short: usually 17 trunk vertebrae, the fewest of any slender salamander in the Relictual Slender Salamander. C: Whitish speckling on the sides; a stripe usually missing in the Sequoia Slender Salamander; blackish-brown with a reddish, yellowish or brown back stripe in the Relictual Slender Salamander. RANGE IS THE SUREST WAY TO TELL THEM APART: where you are decides which one it is; the rows below help confirm it.
