Megastomatohyla
''Megastomatohyla'' is a genus of frogs in the family Hylidae. They are endemic to the cloud forests of central Veracruz and Oaxaca, Mexico. All are rare species with restricted distributions. The generic name is derived from Greek ''mega'' (="large") and stem of the genitive ''stomatos'' (="mouth"), referring to the enlarged oral disc of the tadpoles, juxtaposed with ''Hyla'', the genus in which the four ''Megastomatohyla'' species were previously placed. Common name large-mouthed treefrogs has been coined for this genus. Taxonomy and characteristics ''Megastomatohyla'' was erected in 2005 as a part of a major revision of the Hylidae and corresponds to the former "''Hyla mixomaculata'' group". The delineation was based on molecular data. The only tentative morphological synapomorphy of the genus is the greatly enlarged oral disc of the tadpoles, which has 7–10 anterior rows and 10–11 posterior rows—in those species where this trait is known.

Cloud Forest Tree Frog
The cloud forest tree frog (''Megastomatohyla nubicola'') is a species of frog in the family Hylidae endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and rivers. It is threatened by habitat loss. described the species in 1964; he placed it in the genus ''Hyla''. The specific name, ''nubicola'', Latin for "sky-dwelling", refers to its habitat being a cloud forest.

Hylinae
Hylinae is a large subfamily of "tree frogs", family Hylidae. Classification The contents of this subfamily vary substantially according to the source. The Amphibian Species of the World follows the revision by Duellman and colleagues from 2016 based on molecular data and delimits the subfamily more narrowly than before, treating parts of former Hylinae as their own subfamilies. Following this classification, there were 18 genera totaling 174 species in the end of 2020. They are found North, Central, and the northmost South America, much of temperate Eurasia, Japan, and extreme northern Africa, however, only ''Hyla'' is found outside the Americas. The Wikipedia is following this classification. The AmphibiaWeb follows an older classification defining Hylinae more broadly, with several hundred species. At the end of 2020, the AmphibiaWeb lists 42 genera totaling 737 species. Amphibian Species of the World At the end of 2020, the Amphibian Species of the World includes the follo ...

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'' †...

Endemic Amphibians Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Sierra Madre De Oaxaca
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...
