Zur Morphologie und Biologie von Telmatobius montanus LATASTE 1902, nebst Beschreibung seiner Larve (Amphibia: Leptodactylidae)
1980
Busse, Klaus
As only little is known about the Leptodactylid frog Telmatobius montanus from the Andean range of Santiago de Chile, it has been tried to gather more information about this species. Additional data about the external morphology and its variation are presented as well as photographs of live and preserved adults. The tadpole is also described, using both live and preserved material. The frog is mainly aquatic, having some adaptations to this environment like an increased skin surface by means of folds that are however not so well developed as in some other members of this genus. The larva, adapted to a mountain stream habitat, has a large mouth and a depressed body. Some general aspects of the behaviour of larvae and adults, in the field and in captivity, are documented. Like in various other Telmatobiinae the larval stage lasts long. Adults eat small water insects, mostly at larval stage, and worms. The tadpole feeds on algae and detritus. Adults sometimes have parasitic mites within their skin, especially in somewhat polluted waters. It is possible that the species was restricted to its present range by means of the introduction of salmonids in the andean streams.
