Calyptocephalellidae
The Calyptocephalellidae are a family of toads (although not true members of the Bufonidae) found in Chile containing two living genera, ''Calyptocephalella'' and ''Telmatobufo.'' The genus ''Calyptocephalella'' contains one living species, the helmeted water toad (''C. gayi''), which is very large and mostly aquatic. The genus ''Telmatobufo'' contains four species, '' T. australis'', '' T. bullocki'', '' T. ignotus'', and '' T. venustus''. All five living species within the family are considered threatened, with ''T. bullocki'' and ''T. venustus'' being classified as critically endangered. The family has been present in southern South America since the end of the Cretaceous and were present in the Antarctic Peninsula during the Eocene. While originally widespread in Patagonia east of the Andes, they later became extinct in this region after the Late Miocene, likely due to increasingly cold and arid conditions. A particularly large indeterminate fossil species is known from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calyptocephalella Gayi
''Calyptocephalella'' is a genus of frogs in the family Calyptocephalellidae. It is represented by a single living species, ''Calyptocephalella gayi'', commonly known as the helmeted water toad, Chilean helmeted bull frog or wide-mouth toad. Additionally, there are a few extinct species that only are known from Late Cretaceous and Paleogene fossil remains from Patagonia in South America and in the Antarctic Peninsula (at times when it was warmer and wetter). The helmeted water toad living today is aquatic to semi-aquatic, and found in deep ponds and reservoirs in central Chile and possibly adjacent west-central Argentina.AmphibiaWeb: Calyptocephalella gayi.' Retrieved 21 March 2015. This very large toad typically weighs up to , but sometimes considerably more. It's the world's second largest frog after the goliath frog. It is threatened by capture for human consumption, habitat loss, pollution, introduced species and the disease chytridiomycosis. It is often kept in herpetocultur ...

Australobatrachia
Australobatrachia ("southern frogs") is a clade of frogs in the suborder Neobatrachia. It comprises three families of frogs with a Gondwanan distribution, being known from Chile, Australia, and New Guinea. Together, they form the sister group to the superfamily Hyloidea. Taxonomy The common ancestor of all three families inhabited South America during the Early Cretaceous (about 125 million years ago). By about 100 million years ago, the ancestors of the Calyptocephalellidae diverged from the Myobatrachoidea, as the ancestral Myobatrachoidea moved south, colonizing the Australian continent via then-unglaciated Antarctica. The two families within Myobatrachoidea diverged from each other later in the Cretaceous or during the earliest Paleocene. Australobatrachia contains the following subgroups: * Calyptocephalellidae - Chilean toads (5 species) * Myobatrachoidea ** Limnodynastidae - Australian ground frogs (44 species) ** Myobatrachidae Myobatrachidae, commonly known as Aus ...

Telmatobufo
''Telmatobufo'' is a genus of frogs (false toads) endemic to southern Chile. Their closest living relative is the monotypic helmeted water toad, ''Calyptocephalella gayi''. These frogs were recently removed from the Leptodactylidae and placed in a new family, the Calyptocephalellidae. All three species of ''Telmatobufo'' that have been assessed by the IUCN are considered threatened. Species The four species are: * ''Telmatobufo australis'' Formas, 1972 * ''Telmatobufo bullocki'' Schmidt, 1952 * ''Telmatobufo ignotus'' Cuevas, 2010 * ''Telmatobufo venustus ''Telmatobufo venustus'' is a species of frog in the family Calyptocephalellidae.

Telmatobufo Australis
''Telmatobufo australis'' is a species of frog in the family Calyptocephalellidae.

Telmatobufo Venustus
''Telmatobufo venustus'' is a species of frog in the family Calyptocephalellidae. It is endemic to Chile and occurs on the western slopes of the Andes in Maule and Bío Bío Regions. Its natural habitats are streams in temperate ''Nothofagus'' forests where it is found under rocks along the streams. The only stable population is in the Altos de Lircay National Reserve in Maule. The only other localities, both in the Bío Bío Region, are its type locality in Chillan, where it was not found in 2014, and Ralco where it was last observed in 1981.

Telmatobufo Bullocki
''Telmatobufo bullocki'' is a species of frog in the family Calyptocephalellidae. It is endemic to Chile, and is only known from a few locations in the Cordillera de Nahuelbuta, a part of the Chilean Coast Range. It is extremely rare; extensive fieldwork in 1992–2002 turned up only a single adult. It occurs in fast-flowing streams in temperate ''Nothofagus'' forest. The tadpoles are free-swimming and feed on algae growing on submerged rocks. It is threatened by siltation of streams caused by clear-cutting. It occurs within the Nahuelbuta National Park Nahuelbuta National Park () is one of the few parks located in La Araucanía Region of Chile's Coastal Mountain Range. It sits atop the highest part of the Cordillera de Nahuelbuta. Created in 1939, it consists of 6,832 hectares situated just 16 ....

Toads
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae (helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae (European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae (American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps on the skin ...

Myobatrachoidea
Myobatrachoidea is a superfamily of frogs. It contains two families, both of which are found in Australia, New Guinea, and the Aru Islands. Some sources group these two families into a single family Myobatrachidae. Their closest relatives are thought to be the Calyptocephalellidae of southern South America, from which they diverged during the mid-Cretaceous (about 100 million years ago). Together, they comprise the clade Australobatrachia; their common ancestor is thought to have inhabited South America, with the ancestors of Myobatrachoidea dispersing to Australasia during the Cretaceous via (then ice-free) Antarctica. Both families within Myobatrachoidea are thought to have diverged from each other during the Late Cretaceous or during the earliest Paleocene (immediately after the Cretaceous-Paleogene extinction event). Taxonomy Myobatrachoidea contains the following families: * Limnodynastidae - 44 species * Myobatrachidae Myobatrachidae, commonly known as Australian gr ...
