Water Frog

Telmatobius species are recognised for their remarkable ability to survive at high altitudes and in cold waters (5). Generally, they tend to be secretive frogs that seek seclusion under rocks and stream banks (3). Many species have weak voices or no voice at all, which is thought possibly to be a response to the ambient noise levels of the streams they inhabit (4).

Given the apparent disappearance of the Chilean population of Telmatobius peruvianus, further survey work is needed to determine this species' true status in the region. Currently, it not known from any protected areas in Peru or Chile, and the habitat it occupies is in desperate need of improved protection. In addition, there is a growing need to closely monitor the species' population in view of the potential threat of an infectious disease such as chytridiomycosis, which fortunately has not yet been reported in T. peruvianus (1).

The genus Telmatobius comprises around 50 species of aquatic and semi-aquatic frogs, distributed on the slopes of the Andes, from southern Ecuador to Chile and Argentina (2) (3). Most Telmatobius species are rather drab, medium sized frogs, with bulky bodies, stout forearms, and thick, glandular skin (3). The type species for the genus, Telmatobius peruvianus, is described as having a brown to grey back, and well developed nuptial spines on the chest, throat, and thumb (2). The nuptial spines help the male to cling to the female when mating in fast-moving streams, but may also play a role in male to male combat (4).

This semi-aquatic species is found in streams and small rivers at high elevations (1).

Telmatobius peruvianus is known from the south-eastern Andes in Peru, and a single site in northern Chile, near to the Peruvian border (1).

Classified as Vulnerable (VU) on the IUCN Red List (1).

Owing to the impact of human water consumption and pollution, the Chilean population of T. peruvianus has declined to the extent that it hasn't been recorded since 1986. Although there is little information on its status in Peru, there are several localized threats to this species including habitat loss due to mining and agriculture, and harvesting of frogs for food and medicine. Furthermore, as a high altitude species, T. peruvianus may be particularly vulnerable to infection with the devastating chytrid fungus (1).

Telmatobius peruvianus, also known as the Peru water frog, is a species of frog in the family Telmatobiidae. This semiaquatic frog is endemic to Andean highlands in southeastern Peru and far northern Chile where found in streams and small rivers. It is threatened by habitat loss, pollution, collection for human consumption and infection by chytrid fungi, and it has not been seen in Chile since 1986.
