Bell's False Brook Salamander, Pseudoeurycea bellii, is endemic to Mexico. It was once common, but has disappeared from many places from which it was formerly known. This decline is enigmatic as this salamander is able to tolerate some habitat degradation; it has been found in coffee plantations, rural gardens, grazed areas, and degraded forest, and near urbanized areas.

Eurycea lucifuga: These salamanders are found in and around caves, seeps, springs, springhouses, and small forested limestone creeks associated with groundwater. Cave salamanders live in rock crevices or under rocks, logs, or other debris. The cave salamander is protected as an endangered species by the Ohio Division of Wildlife.
