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'' Lynch, 2008 * '' Cryptobatrachus fuhrmanni'' (Peracca, 1914) * '' Cryptobatrachus pedroruizi'' Lynch, 2008 * '' Cryp ...

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 ar ...

Cryptobatrachus Fuhrmanni
''Cryptobatrachus fuhrmanni'' commonly known as Fuhrmann's backpack frog is a species of frog belonging to the family Hemiphractidae. It is endemic to Colombia and occurs on all three Andean cordilleras: the eastern slope of the Cordillera Occidental, the northern and eastern flanks of the Cordillera Central, and the western slope of the Cordillera Oriental. The specific name ''fuhrmanni'' is in honor of Otto Fuhrmann, a Swiss zoologist and helminthologist. Description Adult males measure and adult females in snout–vent length. The snout is short and the tympanum is small, showing no sexual dimorphism. The dorsolateral folds are thin, and the skin on the dorsum is finely granular with scattered larger warts. The fingers lack webbing but expanded disks at the tips with subarticular adhesive pads present. Female frogs carry eggs on their backs, which undergo direct development, hatching as froglets (i.e., there is no free-living larval stage). Habitat and conservation ''C ...

"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 of frogs from 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'' and '' Fritziana''). 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 the eggs in ... [...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 or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibian. Most tadpoles are fully Aquatic animal, aquatic, though some species of amphibians have tadpoles that are terrestrial animal, ... stage). Th ...

Above Sea Level
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods. Climate change and other forces can cause sea levels and elevations to vary over time. Uses Elevation or altitude above sea level is a standard measurement for: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Mining infrastructure, particularly underground. * Flying objects such as airplanes or helicopters below a Transition Altitude defined by local regulations. Units and abbreviations Elevation or altitude is generally expressed as "metres above mean sea level" in the metric system, or " feet above mean sea level" in United States customary and imperial units.

Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as " tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** '' Boana'' – gladiator treefrogs *** '' Bokermannohyla'' *** '' Hyloscirtus'' *** '' Myersiohyla'' *** '' Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***'' Dendropsophus'' *** ''Xenohyla ** Tribe Hy ...
