Cryptobatrachus
''Cryptobatrachus'' is a genus of frogs in the family Hemiphractidae. They are found in Colombia and Venezuela. They are also known as backpack frogs, as the females have the habit of carrying their egg clutch on their backs until the young hatch; this behavior also occurs in the related hemiphractid genera ''Hemiphractus'' and ''Stefania''. Description ''Cryptobatrachus'' have a treefrog-like habitus. Males measure and females in snout–vent length. Fingers have no webbing whereas the toes are webbed. The finger and toe tips bear disks that are larger on the former. Also adhesive pads are present on the penultimate subarticular tubercles on the fingers. Males lack vocal sac and these frogs appear not to vocalize. Species There are six species in the genus ''Cryptobatrachus'': * ''Cryptobatrachus boulengeri'' Ruthven, 1916 * '' Cryptobatrachus conditus'' , 2008 * '' Cryptobatrachus fuhrmanni'' (Peracca, 1914) * '' Cryptobatrachus pedroruizi'' Lynch, 2008 * '' Cryptobatrach ...

Cryptobatrachus Fuhrmanni
''Cryptobatrachus fuhrmanni'' (common name: Fuhrmann's backpack frog) is a species of frog in the family Hemiphractidae. It is endemic to Colombia and occurs on all three Andean cordilleras: it is found on the eastern slope of the Cordillera Occidental, northern and eastern flanks of the Cordillera Central, and the western slope of the Cordillera Oriental. The specific name ''fuhrmanni'' honors Otto Fuhrmann, Swiss zoologist and helmintologist. Description Adult males measure and adult females in snout–vent length. The snout is short. The tympanum is small and not sexually dimorphic. The dorsolateral folds are thin. Skin on the dorsum is finely granular with scattered larger warts. The fingers have no webbing. The finger and toe tips bear expanded disks. Subarticular adhesive pads are present. Female frogs carry the eggs on their back. The eggs have direct development, hatching as froglets (i.e., there is no free-living larval stage). Habitat and conservation ''Cryptoba ...

Cryptobatrachus Ruthveni
''Cryptobatrachus ruthveni'' is a species of frogs in the family Hemiphractidae. It is endemic to the western flank of the Sierra Nevada de Santa Marta in northern Colombia. The specific name ''ruthveni'' honors Alexander Grant Ruthven, an American herpetologist who was the first one to study . Description Adult males measure and adult females, based on a single specimen, in snout–vent length. The head is wider than it is long and wider than the body in females but not in males or juveniles. The snout is subacuminate in dorsal view but rounded in profile. The tympanum is larger in males than in females; the supratympanic fold is prominent. The dorsolateral folds are thin. Skin on the dorsum is finely granular with scattered larger warts. The fingers have no webbing. The finger and toe tips bear expanded disks. Subarticular adhesive pads are present. Alcohol-preserved specimens are dorsally brown with pale brown blotches on the back and cream spots on the flanks. The limbs a ...

Habitat and conservation ''Cryptobatrachus boulengeri'' are found on rocks within fast-flowing streams in primary and secondary montane forests at elevations of above sea level. This species is abundant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
"Hyla" Nicefori
"''Hyla''" ''nicefori'' also known as the Colombian backpack frog, is a species of frog in the family Hylidae. It is endemic to the border region between Boyacá and Casanare in Colombia and only known from the holotype. The name format, as used by the American Museum of Natural History's ''Amphibian Species of the World'', indicates that while this species is temporarily kept in the hylid type genus ''Hyla'', it belongs elsewhere in the family and will be reassigned pending a taxonomic resolution. It was originally placed in ''Cryptobatrachus'' (backpack frogs), but a later study revealed a number morphological differences showing that it is not in family Hemiphractidae (the family of ''Cryptobatrachus''), instead pointing to it being a hylid frog, perhaps ''Hyloscirtus''. The only known record of the species is the type specimen that was collected in the 1940s and "''Hyla''" ''nicefori'' is rated as data deficient by the IUCN The International Union for Conservation of ...

Hemiphractidae
The Hemiphractidae are a family (biology), family of frogs from South America, South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae (''Flectonotus'' and ''Gastrotheca''), Cryptobatrachidae (''Cryptobatrachus'' and ''Stefania''), and Hemiphractidae (''Hemiphractus''). An active question still exists as to which of these groupings is more accurate. Breeding behavior An unusual and unique adaptation in this family is the breeding behavior where the eggs are carried on the female's back; the eggs may develop into froglets on the back of the female without free-swimming tadpole stage, be released after hatching as tadpoles, or be deposited in water to complete their development there. In some species (genus ''Gastrotheca'' and some ''Flectonotus''), this goes as far as to enclose th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stefania
''Stefania'' is a genus of frogs in the family Hemiphractidae. They are native to the highlands of the Guiana Shield in southern Venezuela, Guyana, and adjacent far northern Brazil. Most are restricted to the tepui highlands, but '' S. evansi'' also occurs in lowlands. On most mountains there are only 1–2 species from this genus, but five are known from Mount Ayanganna and the neighbouring Mount Wokomung has six species. They are usually found near streams at low levels on branches/leaves or on the ground among vegetation/rocks. They are famous for their breeding strategy where the development from eggs to froglets is completed on the back of the female (the eggs hatch to froglets; there is no free-swimming 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 i ... stage). The c ...

Amphibian Species Of The World
''Amphibian Species of the World 6.1: An Online Reference'' (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range. The American Museum of Natural History hosts ''Amphibian Species of the World''. As of 2019, it contained more than 8000 species. History The Association of Systematics Collections (ASC) started this project in 1978 because the Convention on Trade in Endangered Species of Fauna and Flora (CITES) needed a database for animals. (The ASC later changed its name to Natural Science Collections Alliance.) The ASC's Stephen R. Edwards wrote ''Mammal Species of the World'' first and started ''Amphibian Species of the World'' second. Edwards decided to write about living amphibians because Richard G. Zweifel had just composed a large list of amphibian names and because experts from the University of Kansas were available to assist him. Darrel ...
