Ceratophrys cranwelli
An ambush-hunting frog of the dry Gran Chaco of South America. It is 7.5-13 cm long with a very wide mouth and long horn-like projections above the eyes, burrowing into the substrate to wait for prey and reacting strongly to movement.
Ceratophrys cranwelli is a terrestrial frog of the family Ceratophryidae endemic to the dry Gran Chaco of South America. The back is dark green to brown, camouflaging the animal as it burrows and waits for prey, while orange and yellow albino forms are common in the pet trade. Its horn-like projections above the eyes are longer than those of the ornate horned frog and its snout is more protruding. It is normally inactive but an extremely aggressive feeder, leaping several body lengths to seize prey. A row of teeth on the upper jaw means it cannot release prey once seized, and animals occasionally choke on prey that is too large. At temperature extremes it forms a cocoon of thickened skin and aestivates, protecting itself from water loss. In captivity it must be kept alone, as the species is cannibalistic. Captive-bred animals are traded in Japan, but hybrids with the ornate horned frog are common.

Figures published for the genus give a hot spot of 28-29C, general air temperature of 24-27C and night-time temperatures of 18-21C. Average humidity is 60-80 per cent, naturally rising at night. Mist in the evening to raise humidity and never let the substrate dry out completely.
A single adult is said to do well in a ten-gallon aquarium, though some sources recommend a larger 24 x 18 x 18 inch, roughly 29-gallon, enclosure. Provide a moisture-retentive substrate deep enough to burrow into and never gravel, plus a shallow water dish it can half submerge in.
It is carnivorous, taking crickets, roaches, mealworms, earthworms and feeder fish. Dust feeders with a calcium supplement at every other feeding for adults and at every feeding for juveniles. It will take pinkie mice, but these can cause organ problems, so limit how often they are offered.
It will bite at anything that moves, so it must be housed alone to prevent cannibalism. Feed with tongs or a dish rather than by hand. It is normally almost motionless, buried in the substrate with only its eyes showing.
The species is not listed in the CITES appendices, and it is neither a specified animal nor an invasive alien species under Japanese law. Hybrids with the ornate horned frog and other congeners are traded under the name fancy horned frog, so check the lineage of any animal you buy. As an amphibian its skin is sensitive, so wash and wet your hands before handling it.
