Batrachoseps altasierrae·Plethodontidae
Batrachoseps altasierrae is a species of lungless salamander belonging to the genus Batrachoseps, commonly known as slender salamanders. These amphibians are characterized by their slender, snake-like bodies, small limbs, and a distinctive four-toed foot structure. They inhabit a range extending from Oregon and California in the United States down to northern Baja California in Mexico.

About Batrachoseps altasierrae
Batrachoseps altasierrae is a species of lungless salamander belonging to the genus Batrachoseps, commonly known as slender salamanders. This genus is characterized by its members' distinctive four toes on each foot, a feature that helps distinguish them from other lungless salamanders.
Physiology and Diet
Slender salamanders, including Batrachoseps altasierrae, share a common physiology of being lungless. They possess long, slender, snake-shaped bodies and remarkably small limbs that can appear almost vestigial in some species. Their diet primarily consists of small invertebrates, such as springtails, mites, spiders, small bark beetles, crickets, and young snails. Like many salamanders in the Plethodontidae family, they utilize long, projectile tongues to rapidly capture their prey.
A particularly noteworthy physiological trait of the genus Batrachoseps is that their mature red blood cells lack a nucleus. This characteristic is highly unusual, as it is a trait typically found only in mammals and certain species of Antarctic fish, differentiating them significantly from most other vertebrates.
Geographic Distribution
The range of Batrachoseps species extends from the northwestern United States, specifically Oregon and parts of California, southward into northern Baja California, Mexico. Within California, these slender salamanders demonstrate a notable adaptability, capable of tolerating a diverse array of environments, provided their fundamental ecological needs are met.
