Argentine horned frog
species of amphibian

The Argentine horned frog (Ceratophrys ornata), also known as the Argentine wide-mouthed frog, ornate horned frog, ornate horned toad, ornate pacman frog, or just the pacman frog, is a species of frog in the family Ceratophryidae. The species is endemic to South America. It is the most common species of horned frog, in the grasslands of Argentina, Uruguay and Brazil. A voracious eater, it will attempt to swallow anything that moves close to its wide mouth, such as insects, rodents, passerine birds, snakes, lizards, and other frogs, even if this predator would suffocate in the process. It is also kept as an exotic pet. The nickname "pacman frog" is a reference to the popular 1980's arcade game Pac-Man, where Pac-Man himself eats quite a lot, and has a mouth that takes up most of its body, much like the Argentine horned frog.
Description
The females of C. ornata can grow to be 16.5 cm (6.5 in) SVL and the males to 11.5 cm (4.5 in) SVL. 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 red with dark markings do exist. Sexing this species is very difficult before sexual maturity is reached.

Why this record matters
The phrase “species of amphibian” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q954868. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1980.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
