This primitive frog and its closest relative, the coastal tailed frog, are distinctive among frogs and toads in having an intromittent organ, resembling a tail, for internal fertilization. This is an evolutionary adaptation which ensures successful mating in the fast-flowing stream habitat of this species. Tadpoles of this species are also adapted to the strong currents of mountain streams, possessing large sucking mouthparts which they use to hang on to rocks and prevent themselves from being swept downstream.
