California Slender Salamander (Batrachoseps attenuatus)STATUS





Description: The shape of this plethodontid salamander is typically seven to thirteen centimeters in total length. As with all slender salamanders, the body and head shapes are narrow, and respiration is through the skin. This organism has four toes on each foot, as do all genus members. There are between eighteen and twenty-one costal grooves, conspicuous in appearance, lending a worm-like character to this species. Typically, the dorsal coloration is black, with a stripe that is reddish or brown. Ventral marking is dark with minute whitish dotting. B. attenuatus is characterized by moist skin of notable thinness.


Habitat: Batrachoseps attenuatus is found in several plant communities including California oak woodland, redwood forest, Douglas fir forest, montane hardwood conifer, grasslands and riparian zone; occurrence ranges from valley floors to mid-elevation in coastal ranges. From approximately October to March, the California slender salamander seeks cover near streams and other moist environments. This batrachian often may be found resting beneath leaf litter or other woodland detritus, or beneath rotting logs or rocks providing a wet environment. In the dry season commencing in April this species seeks out tunnels or burrows, including rodent homes, to achieve a cooler and moister retreat than available at the surface.


Range: The principal range is within the coastal ranges of Northern California from Monterey County north and including a small amount of southwest coastal Oregon. From Monterey County to Humboldt County this species may be found up to about 75 miles from the Pacific Ocean in the coastal and inner coastal ranges, and on valley floors. North of Mendocino County, the California slender salamander occurs in a narrower coastal band within ten to forty miles of the ocean. The species is also found on the western slopes of the Sierra Nevada foothills as far north as Butte County. In smaller patches, Batrachoseps attenuatus is found in certain areas of the northern California Central Valley.


Found in these States: CA | OR


Diet: The California slender salamander is well adapted to penetration of earthworm or termite burrows to forage for prey, usually consisting of tiny arthropods such as mites, spiders and snails.


Reproduction: Unlike other members of its genus, egg-laying occurs quite early, as soon as December in the southern part of its range. Oviposition is thought to occur primarily in the tunnels of other creatures, but clusters have commonly been found on moist surfaces beneath bark, rocks, or other types of forest detritus. Clutches contain approximately five to twenty individual eggs, but five to ten different females may use the exact oviposition site; in any case, hatching occurs around March or April, somewhat later in the extreme northern part of the range.


Status: Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification and presumed large population.
