Plethtrodon

Plethtrodon is a genus of lungless salamanders belonging to the family Plethodontidae. These salamanders are found in the Americas, with a wide distribution across North and Central America. They are characterized by the absence of lungs, respiring instead through their skin and the lining of their mouths. This adaptation allows them to inhabit moist environments and often leads them to be found in leaf litter, under logs, or in rock crevices.

The genus Plethtrodon is one of the most speciose genera within Plethodontidae, meaning it contains a large number of distinct species. These species exhibit considerable variation in size, coloration, and habitat preference. Many Plethtrodon species are relatively small, while others can grow to be several inches long. Their diets typically consist of small invertebrates such as insects, spiders, and worms.

Reproduction in Plethtrodon species generally involves internal fertilization, with the male depositing a spermatophore that the female then picks up. Females typically lay a clutch of eggs in a protected, moist location and may guard them until hatching. The young are often miniature versions of the adults and are independent from birth. Due to their specific habitat requirements, many Plethtrodon species are sensitive to environmental changes, making them potential indicators of ecosystem health.
