Eurycea – Brook salamanders

Lungless salamander native to North America

These salamanders in the areas of their habitat are locally abundant in suitable habitats, with records of more than 400 specimens found in a single pool. To respire, they rely on gas exchange through their skin and the mucus membrane in their mouth and throat, so these surfaces must always stay moist.

As with all salamanders, the populations of Brook salamanders may decline or be locally extirpated due to intensive timber harvest, other land-use changes, stream pollution, and siltation, or changes in soil chemistry due to “acid rain.”
