Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world. These declines are known as one of the most critical threats to global biodiversity.
The golden coquí is a rare species of frog endemic to Puerto Rico.
Elachistocleis is a genus of microhylid frogs found in southern America from Panama southwards. Their common name is oval frogs, although for historic reasons not all species are named so.
Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. Its name refers to the very large—up to 27 cm (11 in) long—tadpole, which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length. Although the recordholder was a tadpole in Amapá that belonged to this species, others in the genus Pseudis also have large tadpoles and ordinary-sized adults.
Microhyla ornata, commonly known as the ornate narrow-mouthed frog, ornate narrow-mouthed toad, or ornamented pygmy frog, is a species of microhylid frog found in South Asia. This amphibian is distributed in Kashmir, Nepal, peninsular India and the Andaman and Nicobar Islands, Sri Lanka, and Bangladesh. It was previously considered to be the same species as Microhyla fissipes; therefore, the aforementioned common names can refer to either species.
Amolops marmoratus is a species of ranid frog found in Asia. Its common names include marbled sucker frog, marbled cascade frog, Pegu torrent frog, and many others. The taxonomic status of many populations formerly assigned to this species is uncertain.
Sclerophrys perreti is a species of toad in the family Bufonidae. It is endemic to the Idanre Hills in southwestern Nigeria. Sclerophrys perreti is one of the frogs declared as "Lost" in 2010. However, it was re-discovered at its type locality in 2013. Before that, it had not been seen—possibly—since 1970, and with certainty, since 1963. Common name Perret's toad has been coined for it.
Rheobates palmatus is a species of frog in the family Aromobatidae. It is the type species of genus Rheobates erected in 2006. Its common name is palm rocket frog. It is endemic to Colombia. It is considered to be part of a species complex.
Hyperolius vilhenai is a species of frog in the family Hyperoliidae. It is only known from its type locality, Cuílo, along the Luita River in northern Angola, although it is likely to occur in adjacent Democratic Republic of the Congo. Additional specimens from the Cangandala National Park have been provisionally assigned to this species. The specific name vilhenai honours Ernesto Jardim de Vilhena, a Portuguese naval officer, politician, and businessman. Common names Luita River reed frog and Vilhena's reed frog have been proposed for this frog.
Pristimantis rufioculis is a species of frog in the family Strabomantidae. It is found in the Andes of northern Peru and adjacent Ecuador (Zamora-Chinchipe). The specific name rufioculis is derived from the Latin words rufiis, meaning red, and oculis, meaning eye—red iris is one of the distinguishing characteristics of this species. Accordingly, common name red-eyed robber frog has been proposed for this species.
Insuetophrynus is a monotypic genus of frogs in the family Rhinodermatidae. The sole species is Insuetophrynus acarpicus, also known as Barrio's frog. It is endemic to Chile and only known from few localities on the Valdivian Coast Range between Chanchán in the Los Ríos Region in the south and Queule and Colequal Alto in the north; the fourth locality is Mehuín, which is the type locality. The altitudinal range is 50–486 m (164–1,594 ft) asl.
Elachistocleis panamensis is a species of frog in the family Microhylidae. It is found in Colombia and Panama. It is common in some areas in Panama but not considered common in Colombia. It lives in open grassy areas, occasionally within forests, and can also be found in pastures and arable land. It breeds in ponds.
Elachistocleis bicolor is a species of frog in the family Microhylidae. It is found in central Argentina and northward through Paraguay and Uruguay to Amazonian Brazil; earlier reports from Bolivia probably refer to Elachistocleis haroi.
Elachistocleis skotogaster is a species of frog in the family Microhylidae. It is known with certainty only from the Salta Province in northern Argentina. However, the type locality and some later observations are near the border to Bolivia, and it is possible that some frogs from Bolivia currently attributed to Elachistocleis ovalis belong to this species.
Elachistocleis pearsei is a species of frog in the family Microhylidae. It is found in the Pacific versant of western Panama, Caribbean lowlands of Colombia and into the Magdalena River Valley, and in northwest Venezuela. The specific name pearsei honors Arthur Sperry Pearse, an American zoologist.
Cornufer schmidti is a species of frog in the family Ceratobatrachidae. It was first described as a subspecies of Platymantis papuensis. It is the type species of the subgenus Aenigmanura within Cornufer. It is endemic to the Bismarck Archipelago, Papua New Guinea, and is known from the islands of New Britain, New Ireland, and Manus; the Manus population might represent a distinct species.
Odorrana anlungensis is a species of frog in the family Ranidae that is endemic to China: it is only known from its type locality, Mount Longtou in Anlong County, Guizhou. Its common name is Lungtou frog or Anlung odorous frog. Little is known about this species found in shaded hill streams 2-3m wide in forested areas.
The common green frog is a frog species of in the true frog family Ranidae; some sources still use the old name Rana erythraea. It lives in Southeast Asia and is also known as green paddy frog, red-eared frog or leaf frog. The last name, however, commonly refers to the Neotropical tree frogs which make up the subfamily Phyllomedusinae. These are not closely related to H. erythraea, belonging to family Hylidae instead.
Nimbaphrynoides is a monotypic genus of true toads from highlands in the Mount Nimba region of the West African countries of Guinea, Liberia, and Côte d'Ivoire. The sole species is Nimbaphrynoides occidentalis. Along with Nectophrynoides, Eleutherodactylus jasperi, and Limnonectes larvaepartus, Nimbaphrynoides is one of the only anurans that combine internal fertilization with ovoviviparity.
Pristimantis adnus is a species of frog in the family Strabomantidae. It is endemic to Panama and is only known from its type locality in Serranía del Sapo, Darién Province. The species was found while researchers were working on a way to save Panama's frogs from extinction from the deadly amphibian disease chytridiomycosis. The frog was collected in Panama's Darién Province in 2003 and described as a new species in 2010. The name of the species is a Latinized version of the Spanish term for DNA which is ADN.
