Kern Canyon Slender Salamander vs Shasta Salamander
The Kern Canyon slender salamander and the Shasta salamander are both lungless amphibians confined to extremely small areas of California, though at opposite ends of the state and for different underlying reasons.

Kern Canyon Slender Salamander vs Shasta Salamander: common questions
Which of the two salamanders faces a more specific, identifiable threat?
The Shasta salamander faces a specific, long-standing threat in the form of a proposed enlargement of Shasta Dam, which would raise the lake's water level and permanently flood part of its limestone habitat, while the Kern Canyon slender salamander faces more general pressure from any localised disturbance, such as road construction or wildfire, within its narrow canyon range rather than one single named infrastructure project.
How does the Shasta salamander catch prey differently from the Kern Canyon slender salamander?
The Shasta salamander can fire its tongue out to a considerable length to snatch prey, an adaptation well suited to hunting within the narrow limestone crevices it inhabits, while the Kern Canyon slender salamander, like other members of its genus, relies on more direct capture rather than a specialised projectile tongue.
Why are both of these salamanders so vulnerable despite living in different parts of California?
Both species survive within an extremely small natural range, the Kern Canyon slender salamander along a narrow stretch of one canyon and the Shasta salamander around a single lake, so in both cases a disturbance affecting even a modest portion of that already tiny range has the potential to meaningfully impact the entire remaining population of either species.
