Ceuthomantidae
''Ceuthomantis'' is a small genus of craugastorid frogs, also treated as comprising their own monogeneric family Ceuthomantidae. They are found in the southern and eastern parts of the Guiana Highlands in Venezuela, Guyana, and Brazil. The generic name is derived from the Greek noun ''mantis'', which means treefrog, and adjective ''keuthos'', which means hidden, in allusion to the hidden existence of this genus in the tepuis of the Guiana Shield. Taxonomy ''Ceuthomantis'' was first described as the only genus in its own family Ceuthomantidae, but is now merged with Pristimantinae; the oldest name for this taxon is Ceuthomantinae. The AmphibiaWeb maintains Ceuthomantidae as a monogeneric family. ''Ceuthomantis'' is closely related to '' Dischidodactylus'', with which they share a synapomorphy: completely or almost completely divided ungual flaps. Both genera also have dorsal skin composed of small, flat, pliable (not keratinized) warts, and lack nuptial pads in adult males. They d ...

Ceuthomantis Duellmani
''Ceuthomantis duellmani'' is a species of frog in the family Ceuthomantidae. It is endemic to the Sarisariñama tepui, Bolívar state, in the southeastern Venezuela. It is named in honour of , herpetologist from the University of Kansas. Description The type series consists of three males measuring in snout–vent length. Dorsal skin is areolate to tuberculate and green to brown in colour, without any apparent pattern. Some tubercles on head and body are reddish. Tympanum is distinct. Iris is yellow. Ventral surfaces are grey. Third and fourth fingers and third to fifth toes bear broad, medially notched discs that are characteristic for the genus. Males call during the day on humid days and especially after rains. The trill call might be a synapomorphy of the genus. Habitat and conservation ''Ceuthomantis duellmani'' occurs in montane dwarf forest that is completely covered by mosses and other epiphytes. Males call from concealed sites under the ground, or hidden inside roo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Stephen Blair Hedges
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Ceuthomantis Cavernibardus
''Ceuthomantis cavernibardus'' is a species of frog in the family Craugastoridae. It is found in the Sierra Tapirapecó in the Amazonas state of Venezuela as well as in the adjacent Amazonas state of Brazil (where the range is known as Serra do Tapirapecó). The specific name ''cavernibardus'' is derived from the Latin ''caverna'' for "cave" and ''bardus'' for "singer". It refers to the caves commonly used by calling males. Description Adult males measure and females in snout–vent length. The head as wide as the body and slightly longer than it is wide. The snout is rounded to truncate in dorsal view and rounded in lateral view. The tympanum is round to vertically oblong. The fingers and toes have terminal discs but no webbing. Skin on the dorsum and the flanks is granular and weakly tubercular. Dorsal coloration is variable but usually including green, and usually with a dark, vague X-like pattern. Some individuals are uniformly green, greenish black with bright green s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ungual
An ungual (from Latin ''unguis'', i.e. ''nail'') is a highly modified distal toe bone which ends in a hoof, claw, or nail. Elephants and ungulates have ungual phalanges, as did the sauropods and horned dinosaurs. A claw is a highly modified ungual phalanx. As an adjective, ungual means ''related to nail Nail or Nails may refer to: In biology * Nail (anatomy), toughened protective protein-keratin (known as alpha-keratin, also found in hair) at the end of an animal digit, such as fingernail * Nail (beak), a plate of hard horny tissue at the tip ...'', as in ''periungual'' (around the nail).

Vomer
The vomer (; lat, vomer, lit=ploughshare) is one of the unpaired facial bones of the skull. It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomer forms the inferior part of the nasal septum in humans, with the superior part formed by the perpendicular plate of the ethmoid bone. The name is derived from the Latin word for a ploughshare and the shape of the bone. In humans The vomer is situated in the median plane, but its anterior portion is frequently bent to one side. It is thin, somewhat quadrilateral in shape, and forms the hinder and lower part of the nasal septum; it has two surfaces and four borders. The surfaces are marked by small furrows for blood vessels, and on each is the nasopalatine groove, which runs obliquely downward and forward, and lodges the nasopalatine nerve and vessels. Borders The ''superior border'', the thickest, presents a dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
