[1] Frogs in the genus Duellmanohyla breed in fast-flowing mountain streams.

To adapt to this habitat, the frogs have a moderate degree of webbing on the forefeet and on some digits of the hind-feet.

Egg-laying has not been observed in this and other species in the genus, and it is thought that the females may deposit their eggs on the foliage above the water of swift-flowing mountain streams, the tadpoles then falling into the stream when they hatch.

[3] The total area of occupancy of the Chamula mountain brook frog is less than 5,000 square kilometres (1,900 sq mi) and it is only known from five locations.

The montane cloud forests where it lives are under threat from human activities, and although this is quite a common species where it is found, populations of these frogs are thought to be declining.
