Ecology & Habitat
Description
A medium-sized, slender Batrachoseps with a relatively broad head, long limbs, large feet, and a markedly tapered tail; adults are 4-5 cm SVL (Wake 1996, Petranka 1998).
Diagnostic Characteristics
Differs from other attenuate members of the genus by the combination of its relatively broad head, long limbs, wide feet, tapering tail of moderate length, and distinctive color pattern, including markings of bright pigmentation; differs from all other members of the genus in allozymes and mtDNA (Wake 1996).
Habitat
Has been found under rocks, wood, or fern fronds on a steep northwest-facing talus slope shaded by Quercus chrysolepis and Pseudotsuga macrocarpa, on soil along Soldier Creek at the base of the talus slope, and under rocks and logs 10-15 m from a stream in Rockbound Canyon (Wake 1996).
Ecology
As many as three adults have been found under the same rock, suggesting low aggressiveness or lack of strong territoriality (Wake 1996, Petranka 1998).
Reproduction
Terrestrial breeder.
