The California slender salamander (Batrachoseps attenuatus) is a lungless salamander [2] that is found primarily in coastal mountain areas of Northern California, United States as well as in a limited part of the western foothills of the Sierra Nevada, California, in patches of the northern Central Valley of California, and in extreme southwestern Oregon.
The California giant salamander is endemic to Northern California and lives up to 6,500 feet (2,000 m) primarily in damp, coastal forests including coast Douglas fir (Pseudotsuga menziesii var. menziesii) and California coast redwood (Sequoia sempervirens) in both montane and valley-foothill riparian habitats. They tend to be common where they ...
The mudpuppy jaw is considered metaautostyly, like most amphibians, meaning the jaw is more stable and that the salamander has a dentary. [15] This affects their diet by limiting the flexibility of the jaw to take in larger prey. The mudpuppy has few predators which may include fish, crayfish, turtles, and water snakes. Fishermen also ...
The California tiger salamander (Ambystoma californiense) is a vulnerable amphibian native to California. It is a mole salamander . Previously considered to be a subspecies of the tiger salamander ( A. tigrinum) , the California tiger salamander was recently designated a separate species again. [ 4 ]
Due to the extremely dry summer climate in coastal California and neighboring northwest Baja California, B. major (along with almost every other coastal California salamander) is only active above ground in the wetter winter months, typically from as early as October to as late as June. These salamanders are active near the surface when soil ...
The coastal giant salamander can reach up to 33 cm (13 in) in total length as a terrestrial adult, and 35.5 cm (14.0 in) in paedomorphic forms, [4] making it the largest terrestrial salamander in North America. [5] The coastal giant salamander has stout limbs with four toes on the front feet and five toes on the back feet.
Aquatic salamander abundance has been shown to increase with increasing rock coverage, and decrease with increasing water velocity, and tend to prefer cold mountain streams and lakes. [7] Pacific giant salamanders also utilize terrestrial refuge sites such as decaying wood, burrows, or under rocks.
Its distribution was likely fragmented by the creation of the lake and the construction of the Shasta Dam. Proposals to raise the water levels of the lake would likely flood more habitats and further threaten it. However, in 2021 the U.S. Fish and Wildlife Service found the species to not warrant Endangered Species Act protections. [6] [7]
