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 or grazers (Chacophrys).
Pleurodema is a genus of leptodactylid frogs from South America. They are sometimes known under the common name four-eyed frogs, although this name can also refer to a particular species, Pleurodema bibroni. The common name is a reference to two inguinal poison glands that resemble eyes. When threatened, the frog lowers its head and raises its rear. When the frog adopts this posture, the poison glands are also raised toward the predator. The predator may also confuse the frog's raised posterior for the head of a larger animal.
Pyxicephalus is a genus of true frogs from Sub-Saharan Africa, commonly referred to as African bull frogs or bull frogs. They are very large to large frogs, with females significantly smaller than males. They may take decades to reach their full size potential and they are some of the longest-living frogs, possibly able to reach ages as high as 45 years.
Kalophrynus is a genus of microhylid frogs. It is the only genus in the subfamily Kalophryninae. The species in this genus are found in southern China, in Southeast Asia to Java and Philippines, and in Assam, India.
Leptobrachium hasseltii is a species of toad found in Southeast Asia. This frog named after Dutch Naturalist Johan Conrad van Hasselt. According to the current understanding, this species is known with certainty only from Java, Madura, Bali, and Kangean Islands, Indonesia. The species is also commonly reported to occur in the Philippines, but these are believed to refer to another, unnamed species.
The smooth-sided toad or spotted toad, formerly known as Bufo guttatus, is a species of toad in the family Bufonidae. It is found in the Amazonian Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela, as well as the Guianas. Specimens from southern Peru, Bolivia, and Brazil might represent Rhaebo ecuadorensis described in 2012.
The raucous toad, also known as Ranger's toad, is a species of toad from Southern Africa.
Melanophryniscus klappenbachi is a species of toad in the family Bufonidae. It is found in the Gran Chaco in northern Argentina, Paraguay, and Brazil, and possibly in Bolivia. Its specific name refers to Miguel Angel Klappenbach, a Uruguayan zoologist.
The blue-bellied poison frog or bluebelly poison frog is a species of frog in the family Dendrobatidae.
Physalaemus olfersii is a species of frog in the family Leptodactylidae. It is endemic to southeastern Brazil and is known from Espírito Santo, southeastern Minas Gerais, and São Paulo states. Records further south refer to Physalaemus lateristriga, which was restored from the synonymy of Physalaemus olfersii in 2010. Common name Atlantic Forest dwarf frog has been proposed for this species.
The Colombian four-eyed frog is a species of frog in the family Leptodactylidae. It is found in an area stretching from Guyana and northern Brazil through Venezuela and Colombia into Panama as well as the Netherlands Antilles.
Pleurodema bufoninum, the large four-eyed frog, is a species of frog in the family Leptodactylidae. It is found in Argentina and Chile. Its natural habitats are subantarctic forests, temperate forests, subantarctic shrubland, temperate shrubland, subtropical or tropical dry shrubland, subantarctic grassland, temperate grassland, intermittent rivers, swamps, intermittent freshwater marshes, arable land, rural gardens, ponds, and open excavations. The common name "four-eyed frog" refers to two inguinal poison glands that resemble eyes. When threatened, the frog lowers its head and raises its rear. When the frog adopts this posture, the poison glands are also raised toward the predator. The predator may also confuse the frog's raised posterior for the head of a larger animal.
Pleurodema cinereum is a species of frog in the family Leptodactylidae. It is found in the Andes in northwestern Argentina, Bolivia, and southeastern Peru. Its common name is Juliaca four-eyed frog, after its type locality, Juliaca. Pleurodema borellii is possibly a junior synonym of this species.
Pleurodema diplolister, the Peters' four-eyed frog, is a species of frog in the family Leptodactylidae. It is endemic to Brazil. Its natural habitats are dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical dry lowland grassland, intermittent freshwater marshes, sandy shores, and pastureland. It is threatened by habitat loss. The common name "four-eyed frog" refers to two inguinal poison glands that resemble eyes. When threatened, the frog lowers its head and raises its rear. When the frog adopts this posture, the poison glands are also raised toward the predator. The predator may also confuse the frog's raised posterior for the head of a larger animal.
Pleurodema somuncurense is a species of frog in the family Leptodactylidae. It is endemic to the Somuncura Plateau in Patagonia, Argentina.
Kuhl's creek frog or large-headed frog is a species of frog in the family Dicroglossidae.
Ptychadena pujoli is a species of frog in the family Ptychadenidae. It is known from Macenta and Sérédou in Guinea, Sukurela in Sierra Leone, and Mount Nimba in Liberia and Ivory Coast. Description of Ptychadena pujoli is based on old museum specimens, and very little is known about the ecology of this relatively recently (1997) described species.
The Leiuperinae are a subfamily of frogs in the family Leptodactylidae. Over 90 species are in five genera. The distribution of this subfamily is from southern Mexico to the Central America and much of South America.
Pleurodema cordobae is a species of frog in the family Leptodactylidae. It is endemic to the Sierras de Córdoba of Argentina. This endemic species also resides with the highly similar species, Pleurodema kriegi. P. cordobae exhibits particular characteristics that differentiate it from other frogs in the Pleurodema genus, including the fact that the species is octoploid, as compared to the P. kriegi and Pleurodema bibroni, which are tetraploid. P. cordobae inhabits temporary and semi-permanent ponds. As this species is only found in isolated locations such as the Sierra Grande, little is known about its very limited population.
Theloderma lateriticum, the brick-red bug-eyed frog, is a frog in the family Rhacophoridae. It is native to Vietnam and China and has been observed 1130 meters above sea level.
