Gregarious Slender Salamander vs Tehachapi Slender Salamander
The gregarious slender salamander and the Tehachapi slender salamander are both lungless amphibians in the genus Batrachoseps found in overlapping parts of southern California, yet their conservation outlooks could hardly be more different.

Gregarious Slender Salamander vs Tehachapi Slender Salamander: common questions
Why is one of these salamanders Endangered and the other isn't?
The Tehachapi slender salamander is known from only a small number of isolated, fragmented canyon sites within the Tehachapi and Piute Mountains, so severe habitat loss at even a single location could meaningfully affect the entire species, while the gregarious slender salamander is found more continuously across suitable forest and grassland habitat in the southern Sierra Nevada foothills, giving it a more secure overall population.
What does "gregarious" mean for this species of salamander?
The gregarious slender salamander is frequently found sheltering together with several other individuals of the same species beneath a single log or rock, an unusually social tendency toward aggregation that is genuinely uncommon among slender salamanders, which typically shelter alone, and this behaviour is exactly what gave the species its common name.
Do both salamanders live in the same part of California?
They live in nearby but distinct mountain ranges of southern California, with the gregarious slender salamander restricted to the southern Sierra Nevada foothills and the Tehachapi slender salamander confined to isolated canyons within the neighbouring Tehachapi and Piute Mountains, two ranges close enough geographically to host closely related species but distinct enough to keep each species' population separate.
