Euparkerella
''Euparkerella'', sometimes known as Guanabara frogs, is a genus of frogs in the family Strabomantidae. They are endemic to the Atlantic coastal forests in the south-eastern Brazilian states of Espírito Santo and Rio de Janeiro. The name ''Euparkerella'' honours H. W. Parker, a herpetologist who named the type species, with the Greek prefix ''eu'' meaning true and suffix ''ella'', a diminutive form. Taxonomy Species of ''Euparkerella'' are traditionally distinguished using morphological traits. However, these species do not align well with genetically distinct units, with the latter suggesting higher diversity than the former, especially within '' Euparkerella brasiliensis'' and '' Euparkerella cochranae''. It remains unresolved whether the genetically distinct units qualify as different species. Description Species of ''Euparkerella'' are small frogs, growing to snout–vent length at most. The digits are extremely reduced, compared to those of their larger relatives. Head is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Euparkerella Robusta
''Euparkerella robusta'' is a species of frog in the family Strabomantidae. It is endemic to the state of Espírito Santo in southeastern Brazil. It has been recorded from the municipality of Mimoso do Sul ( type locality) and the neighboring Atílio Vivacqua. Common name Izecksohn's Guanabara frog has been proposed for it. Description The body is robust. Adult males measure in snout–vent length. It is a large member of its genus; it differs from the other large species, ''Euparkerella tridactyla'', by its longer fingers. The male advertisement call consists of a single note comprising 5–8 long pulses repeated periodically. The pulses are relatively long and have a whistle-like character (as opposed to short snaps in other ''Euparkerella''). The call duration is 1.3–2.2 seconds and the dominant frequency is 2.9–3.2 kHz. Habitat and conservation ''Euparkerella robusta'' occurs in leaf litter in primary and secondary forest. Development is direct (i.e., there is no fr ...

Strabomantidae
The Strabomantidae are a family of frogs native to South America. These frogs lack a free-living larval stage and hatch directly into miniature "froglets". This family includes ''Pristimantis'', the most speciose genus of any vertebrate.

Amphibian Genera
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 ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
