Description: Formally known as Caudiverbera caudiverbera (a mythical species) but was renamed in 2006. From Chile (and probably Argentina), this large, aquatic amphibian lives in lakes and other permanent deep bodies of water. It is heavy bodied with small eyes and a blunt, rounded nose on its’ big head. The fingers have no webbing, the feet are partially webbed and the skin is bumpy with a brownish color. Males grow to 4¾" and the females are about twice as large.
They are used for food by the local people and are in decline due to over-collecting, the impact of development and harm caused by introduced trout. They do not seem to be exported for the pet trade but are considered to be a vulnerable species by the IUCN and critically endangered by the Chilean government. Some measures have been taken to increase wild populations but so far captive breeding efforts are not working.

Temperature: 72° to 78°F.

Humidity: Not important.

Lighting: Fluorescent grow lights may be needed if live plants are to be included in the habitat. Use a timer to provide a 12-hour day cycle.

Feeding: Fish and other aquatic creatures, insects, good quality sinking fish foods as well as frozen fish foods.

Habitat: A larger size tank is needed for these frogs. An aqua-vivarium is the most attractive setup, allowing the addition of some terrestrial plants. The water portion should have a substantially deep end that slopes up to the land area with easy access to leave the water.
They will also thrive in a completely aquatic habitat. Provide a deep end that slopes up to the shallow end. A sparsely decorated setup with minimal furnishings can also work well.
Regardless of the type of setup, water quality must be maintained. Even if a filter is used, the habitat must still be cleaned and the water changed on a regular basis.
