The California slender salamander (Batrachoseps attenuatus) is a small, lungless amphibian native to coastal and foothill regions of California and southern Oregon. Its coloration varies from brown to reddish or grayish, often with a faint dorsal stripe. It has an elongated, narrow body, measuring 3 to 5.5 inches in length, with short limbs and a long tail that can make up more than half its body length. It thrives in moist environments, such as leaf litter, under logs, and in crevices, where it avoids desiccation. The California slender salamander is entirely terrestrial, bypassing the aquatic larval stage common in many salamanders; eggs are laid in moist soil, and hatchlings emerge as miniature adults. This salamander is a nocturnal predator, feeding on small invertebrates like mites, ants, and spiders. This species relies on its slender body and flexible movements to navigate tight spaces. When threatened, it can autotomize (drop) its tail as a defense mechanism.
Fun fact: California slender salamanders, and all other members of the Batrachoseps genus, have no lungs and rely on moist skin to absorb oxygen directly from the air.
