Telmatobius culeus, commonly known as the Titicaca water frog, is a very large and critically endangered species of frog in the family Telmatobiidae.[2] It is entirely aquatic and only found in Lake Titicaca and rivers that flow into this lake in South America. While the lungs are greatly reduced, this frog has excessive amounts of skin, used to help the frog respire in the high altitude in which it lives.[3]

In reference to its excessive amounts of skin, it has also jokingly been referred to as the Titicaca scrotum water frog.[4]

In the early 1970s, an expedition led by Jacques Cousteau reported frogs up to 50 cm (20 in) in outstretched length, with individuals commonly weighing 1 kg (2.2 lb), making these some of the largest exclusively aquatic frogs in the world (the fully aquatic Batrachophrynus macrostomus is larger, as is the African goliath frog, which sometimes can be seen on land). The snout-vent length is 7.5–13.8 cm (3.0–5.4 in).[3]

Conservation status

Once common, the Titicaca water frog has declined drastically and is now facing extinction due to over-collecting for human consumption, pollution, and predation of tadpoles by introduced trout.[2] It may also be threatened by the disease chytridiomycosis.[2] Several other species in the genus Telmatobius are facing similar risks.[2]

In October 2016, 10,000 Titicaca water frogs at Lake Titicaca died, drastically reducing their numbers. Scientists believe pollution killed the frogs.[5][6]

Facts

They are the largest true aquatic frog. It has extremely loose folds of skin that hangs off from multiple parts of their body.

Diet

The Titicaca Frog diet mainly is, small amphipods, insects, snails and fish.
