Description |
| Size |
| Adults are 1 1/4 - 1 7/8 inches long (3.2 - 4.7 cm) from snout to vent. |
| Appearance |
| A small slim plethodontid salamander, which breathes through smooth moist thin skin. 18-20 costal grooves. Short limbs, a narrow head, long slender body, very long tail, and conspicuous costal and caudal grooves give this species the worm-like appearance typical of most Slender Salamanders. 4 toes on front and hind feet, also typical of Slender Salamanders. (Other California salamanders have 5 toes on the hind feet.) Dark brown or black above with a brownish or rusty dorsal stripe which is usually absent or not apparent. Whitish speckling is extensive, especially on the sides. Venter is gray and lighter than the sides. |
| Behavior |
| Most Batrachoseps are active on rainy or wet nights when temperatures are moderate, fall through spring, retreating underground when the soil dries or when air temperature drops to near freezing. At higher elevations, activity may be restricted to spring and early summer and early fall. Found under rocks, logs, bark, and other debris. Batrachoseps species, when disturbed, may coil up and remain still, then uncoil quickly and spring away, repeatedly bouncing over the ground. The tail is easily broken off, but it can be regenerated. Probably a sit-and-wait predator. Occurs in sympatry with B. gregarius. and sympatry with B. relictus is possible. |
| Diet |
| Probably eats a variety of invertebrates. |
| Reproduction |
| Batrachoseps lay eggs in moist places on land. Young hatch fully formed. |
| Range |
| Endemic to California. Found only in the Kaweah river drainage in Tulare county. |
| Habitat |
| Inhabits areas with scattered trees, and in mixed coniferous forest at higher elevations. 1,640 - 7,200 ft. (500 - 2,200 m.) |
| Taxonomic Notes |
| Prior to its description in 1998, B. kawia would have been identified as B. pacificus. |
| Conservation Issues (Conservation Status) |
| Listed as imperiled by NatureServe, the reason why is not clear. |
