Compare two species

Gabilan Mountains Slender Salamander vs. California Slender Salamander

The two meet around Monterey Bay and the Santa Cruz Mountains; elsewhere range decides. A: Rather robust, with fairly long legs in the Gabilan Mountains Slender Salamander; very slim and worm-like, with tiny legs in the California Slender Salamander. B: A reddish or tan stripe down the back in the Gabilan Mountains Slender Salamander; dark, with a faint stripe or none in the California Slender Salamander. These are hard even for experts: where they meet, a slender salamander may need its location or genetics to be named.
