description Titicaca Water Frog Overview
The Titicaca water frog (Telmatobius culeus) is a fully aquatic amphibian endemic to Lake Titicaca, situated on the border of Peru and Bolivia. It is the world's largest exclusively aquatic frog, inhabiting the lake's depths at altitudes exceeding 3,800 meters. The species possesses excessive folds of skin, a physiological adaptation that allows it to cutaneously respire in the oxygen-poor waters of the Andes. The frog is currently classified as critically endangered due to pollution and habitat loss.
help Titicaca Water Frog FAQ
Why does the Titicaca water frog have so much loose skin?
Its skin has folds that increase the surface area available for absorbing oxygen from cold, high-altitude water. The frog can move its body to circulate fresh water over these folds.
Does the Titicaca water frog ever live on land?
Telmatobius culeus is fully aquatic and is strongly adapted to life in Lake Titicaca. It lives at an elevation above 3,800 meters on the Peru-Bolivia border.
Why is the Titicaca water frog critically endangered?
Major pressures include pollution, introduced fish, habitat degradation, disease, and collection for human consumption. Its restricted Lake Titicaca range makes population losses especially serious.
Is the Titicaca water frog really the world's largest aquatic frog?
It is widely described as the largest fully aquatic frog, with unusually large individuals reaching impressive body sizes. It should not be confused with the African goliath frog, which is larger overall but is not fully aquatic.
