Tojologue Water Frog

Telmatobius timens is a critically endangered aquatic frog endemic to high-altitude freshwater systems in the Andes Mountains of South America. This species belongs to the genus Telmatobius, commonly known as water frogs or Titicaca frogs, which are characterized by their adaptation to cold, oxygen-poor environments at extreme elevations. Like other members of its genus, T.

timens has evolved specialized physiological features including increased skin surface area for cutaneous respiration and tolerance to low temperatures. The species inhabits pristine mountain streams, springs, and associated wetland areas where water quality and flow patterns are critical for survival. Its distribution is highly restricted to specific watersheds within a narrow altitudinal range.

The primary threats to T. timens include habitat degradation from mining activities, agricultural runoff, and infrastructure development in highland areas. Water pollution from heavy metals and agricultural chemicals poses significant risks to both adult frogs and their aquatic larvae.

Climate change represents an additional threat through altered precipitation patterns and temperature regimes that affect water availability and quality in high-altitude ecosystems. The species also faces pressure from the introduction of non-native fish species and the fungal pathogen Batrachochytrium dendrobatidis, which has devastated amphibian populations throughout the Andes. Conservation efforts focus on habitat protection, water quality monitoring, and research into disease management strategies, though the species' extremely limited range makes population recovery challenging.

This species inhabits cold, high-altitude freshwater systems including mountain streams, springs, and associated wetlands in the Andes Mountains. It requires pristine water conditions with specific temperature and flow characteristics typical of extreme elevation aquatic environments.
