Cryptobatrachus Conditus
''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 Boulengeri
''Cryptobatrachus boulengeri'', also known as Boulenger's backpack frog, is a species of frogs in the family Hemiphractidae. It is endemic to Sierra Nevada de Santa Marta in northern Colombia. The specific name honours George Albert Boulenger, an eminent herpetologist. Description Adult males measure and adult females in snout–vent length. The snout is relatively long. The tympanum is larger in males than in females. 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 ''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] |
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.

Amphibians Of South America
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Nocturnality
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active d ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

"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 ...

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'' *** '' Julianus'' *** ''Lysapsus'' †...

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 ...

AmphibiaWeb
AmphibiaWeb is an American non-profit website that provides information about amphibians. It is run by a group of universities working with the California Academy of Sciences: San Francisco State University, the University of California at Berkeley, University of Florida at Gainesville, and University of Texas at Austin. AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. It added its 7000th animal in 2012, a glass frog from Peru. As of 2022, it hosted more than 8,400 species located worldwide. Beginning Scientist David Wake David Burton Wake (June 8, 1936 – April 29, 2021) was an American herpetologist. He was professor of integrative biology and Director and curator of herpetology of the Museum of Vertebrate Zoology at the University of California, Berkeley. Wak ... founded AmphibiaWeb in 2000.
