Description
Chaco Frog (Chacophrys pierottii)
The True Chaco Frog is a fascinating and unusual amphibian native to the Gran Chaco region of South America. Often confused with the more commonly kept Pac-Man Frog, this distinctive species has its own unique appearance, featuring a broad, flattened head, prominent eyes, powerful jaws and beautifully camouflaged colouration.
Unlike the Chaco Horned Frog (Ceratophrys cranwelli), the True Chaco Frog belongs to the genus Chacophrys and is a separate species. Its unusual appearance, secretive nature and impressive ambush-feeding behaviour make it a particularly interesting addition to a specialist amphibian collection.
Habitat
True Chaco Frogs are terrestrial amphibians adapted to the seasonal environments of South America's Gran Chaco region. They spend much of their time concealed and require a carefully maintained enclosure.
-
Enclosure: Secure, well-ventilated terrestrial vivarium with adequate floor space
-
Temperature: Approximately 23–27°C during active periods, with a slight nighttime reduction
-
Humidity: Moderate to high humidity during active periods, with access to a consistently moist retreat
-
Lighting: A consistent day/night cycle should be provided, with suitable low-level UVB beneficial
-
Decor: Cork bark, hides, plants and sheltered areas to provide security
-
Water: A shallow dish of clean, dechlorinated water should always be available
-
Maintenance: Maintain appropriate moisture levels without allowing the enclosure to become excessively wet or stagnant
True Chaco Frogs experience pronounced seasonal changes in their natural habitat, including periods of dormancy during dry conditions. These seasonal requirements make them more specialised than many commonly kept frogs.
Feeding
True Chaco Frogs are carnivorous ambush predators that rely on remaining concealed before striking at passing prey.
-
Diet: Appropriately sized crickets, locusts, roaches, earthworms and other suitable feeder invertebrates
-
Juveniles: Offer appropriately sized food regularly during active feeding periods
-
Adults: Feed according to activity, appetite and body condition, generally a few times per week when actively feeding
-
Supplementation: Feeder insects should be appropriately supplemented with calcium and vitamins
-
Feeding Behaviour: Powerful ambush predators capable of striking rapidly at nearby prey
-
Water: Fresh, dechlorinated water should always be available
Feeding behaviour may vary with seasonal activity, and individuals may naturally reduce their food intake during periods of dormancy.
General Care
True Chaco Frogs are best suited to keepers with some amphibian experience, particularly those familiar with species that experience seasonal changes in activity.
-
Temperament: Generally secretive and sedentary, although defensive when disturbed
-
Handling: Handling should be avoided unless absolutely necessary due to their delicate, permeable skin
-
Adult Size: Approximately 4–6cm, with females generally larger than males
-
Lifespan: Potentially several years with appropriate specialist care
-
Activity: Primarily nocturnal, spending much of their time concealed
-
Housing: Best housed individually
-
Seasonal Behaviour: May enter periods of dormancy in response to environmental changes
-
Maintenance: Correct environmental conditions, clean water and careful observation are essential
Their specialised seasonal behaviour means that True Chaco Frogs are generally better suited to experienced amphibian enthusiasts rather than first-time frog keepers.
