The Ouachita dusky salamander grows to about 17.8 centimetres (7.0 in) in length including a finned tail.

[2][3] The Ouachita dusky salamander occurs in mountainous areas of Arkansas and Oklahoma.

They live in and near mountain streams and the ravines and woodland close by, on scree slopes, in gravelly areas, on islands and near springs.

The female deposits twenty to thirty eggs in a grape-like cluster under rocks or in mud chambers usually on land.

There may be a slow decline in numbers but these have not been quantified and there are thought to be more than 10,000 individuals across its range.
