Ceratophryidae
The Ceratophryidae, also known as common horned frogs, are a family of frogs found in South America. It is a relatively small family with three extant genera and 12 species. Despite the common name, not all species in the family have the horn-like projections at the eyes. They have a relatively large head with big mouth, and they are ambush predators able to consume large prey, including lizards, other frogs, and small mammals. They inhabit arid areas and are seasonal breeders, depositing many small eggs in aquatic habitats. Tadpoles are free-living and carnivorous (''Ceratophrys'' and ''Lepidobatrachus'') or grazers (''Chacophrys''). Some species (especially from the genera ''Ceratophrys'' and ''Lepidobatrachus'') are popular in herpetoculture. The oldest fossils of the family are known from the Miocene epoch. The fossil giant frog '' Beelzebufo'' from the Late Cretaceous of Madagascar was formerly considered to belong to this family, but is now excluded, but is possibly closely ...

Ceratophrys
''Ceratophrys'' is a genus of frogs in the family Ceratophryidae. They are also known as South American horned frogs as well as Pacman frogs due to their characteristic round shape and large mouth, reminiscent of the video game character Pac-Man. Species There are eight species: Sex differentiation The female frog will typically not "chirp" or "croak" as often as males, but does sometimes. Males frequently have spotted chests, and at about a year old the males develop spots on their "pads" or "fingers." Males will also sometimes have subtle pads on their front legs during mating season, as well as making a sound similar to a cicada to call to their mates. The female frog is also generally larger than the male frog. Care in captivity In captivity, ''C. cranwelli'', ''C. ornata'' and ''C. cornuta'' are the most popular species, along with the "fantasy frog", a captive-produced hybrid between ''C. cranwelli'' and ''C. cornuta''. These frogs can live in a 10-gallon aquarium for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidobatrachus
''Lepidobatrachus'' is a genus of ceratophryidid frogs. They are commonly known as Paraguay horned frogs or Budgett's frogs (in honor of John Samuel Budgett, who described the genus), although the latter technically describes a specific species, '' Lepidobatrachus laevis''. Geographic range ''Lepidobatrachus'' are found in South America, in Paraguay, Argentina, Brazil, and Bolivia. Description ''Lepidobatrachus'' frogs are generally a light, olive green in color, sometimes with lighter green or yellow mottling. They have a rounded, flattened body with eyes set high on their head. They have short limbs, which make them inefficient swimmers. They do not have teeth, but they do have two sharp protrusions, common to all Ceratophryidae, inside their mouth In animal anatomy, the mouth, also known as the oral cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beelzebufo
''Beelzebufo ampinga'' ( or ) was a particularly large species of prehistoric frog described in 2008. Common names assigned by the popular media include devil frog, devil toad, and the frog from hell. Fossils of ''Beelzebufo'' have been recovered from strata of the Maevarano Formation in Madagascar, dating to the late Cretaceous period, some 70 million years ago (Mya). It is considered to be closely related to ''Baurubatrachus'' from the Late Cretaceous of Brazil, with both possibly being close relatives, though not members of, the extant South American frog family Ceratophryidae. Discovery The first fossil bones were found in 1993 by David W. Krause of New York's Stony Brook University, but it took 14 years for scientists Susan E. Evans, Marc E. H. Jones, and Krause to assemble enough data for publication in the '' Proceedings of the National Academy of Sciences,'' the journal of the United States National Academy of Sciences.

Chacophrys
''Chacophrys pierottii'', the Chaco horned frog or lesser Chini frog, is a species of frog in the family Ceratophryidae. It is monotypic within the genus ''Chacophrys''. It is found in the Chaco of northern Argentina, eastern Bolivia, and western Paraguay. Its natural habitats are dry shrubland and gallery forest. Outside the breeding season adults remain buried underground but emerge during the first heavy rains to breed in temporary ponds. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ... caused by agriculture and wood extraction. It is also collected for pet trade.

Baurubatrachus
''Baurubatrachus'' is an extinct genus of prehistoric frogs found in the Maastrichtian Marília Formation of Brazil, formerly considered to be related to the extant family Ceratophryidae. However, a detailed assessment of the anatomy and relationships of the single known fossil of ''Baurubatrachus'' demonstrated that it is not part of Ceratophryidae and might be part of a much ancient group of Neobatrachia. Discovery and species The type species of the genus, ''B. pricei'', was found in the Serra da Galga Formation (formerly called the Serra da Galga Member of the Marília Formation), near Peirópolis (Minas Gerais, Brazil), 200 km north of Catanduva City. A second species, ''B. santosdoroi'', was described in 2022 and the remains of two individuals were discovered in the Adamantina Formation cropping out near Catanduva city, São Paulo, Brazil.

Ceratophrys Ornata
The Argentine horned frog (''Ceratophrys ornata''), also known as the Argentine wide-mouthed frog, ornate horned frog, ornate horned toad, or the ornate 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, 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 centimeters (6.5 inches) snout to vent (SV) and the males 11.5 centimeters (4.5 in) SV. The average lifespan is 6 ...

Frog
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" '' Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpol ...

Batrachylidae
Batrachylidae is a family of frogs from southern South America (Argentina and Chile). Before being recognized as a family, Batrachylidae was included as a subfamily (Batrachylinae) in the family Ceratophryidae; this is the taxonomy still suggested by the Integrated Taxonomic Information System (ITIS). Species There are four genera in the family: *''Atelognathus'' Lynch, 1978 (5 species) *''Batrachyla'' Bell, 1843 (5 species) *''Chaltenobatrachus'' Basso, Úbeda, Bunge, and Martinazzo, 2011 (1 species) *''Hylorina ''Hylorina sylvatica'' (also known as the Emerald forest frog, or in Spanish, sapo arboreo) is a species of frog in the family Batrachylidae.

Leptodactylidae
The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes. They are a diverse family of frogs that most likely diverged from other hyloids during the Cretaceous. The family has undergone major taxonomic revisions in recent years, including the reclassification of the former subfamily Eleutherodactylinae into its own family the Eleutherodactylidae; the Leptodactylidae now number 206 species in 15 genera distributed throughout Mexico, the Caribbean, and Central and South America. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of habitats. Several of the genera within the Leptodactylidae lay their eggs in foam nests. These can be in crevices, on the surface of water, or on forest floors. These foam nests are some of the most varied among frogs. When eggs hatch in nests on the forest floor, the tadpoles remain within the nest, without eating, until metamorphosis. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
