The Argentine horned frog (Ceratophrys ornata), also known as the Argentine wide-mouthed frog or the ornate pacman frog, is a species of frog in the family Ceratophryidae.
The females of C. ornata can grow to be 16.5 centimeters (6.5 inches) snout to vent (SV) and the males 11.5 centimeters (4.5 in) SV. The average lifespan is 6 to 7 years, however they can live up to 10 years or more in captivity. A horned frog’s most prominent feature is its mouth, which accounts for roughly half of the animal’s overall size. Coloration is typically bright green with red markings, though dark green, parti-color black and albino versions also exist. Sexing this species is very difficult before sexual maturity is reached. Dimorphism traits between the two sexes are size difference and males possessing dark pigmented throats and nuptial pads on the forelimbs.
