Chiasmocleis Cordeiroi
''Chiasmocleis cordeiroi'' is a species of frog in the family Microhylidae. It is endemic to Bahia in eastern Brazil. It is known from Camamu, its type locality, and from few other localities on both sides of the De Contas River. The specific name ''cordeiroi'' honors Paulo Henrique Chaves Cordeiro, a Brazilian biologist. Common name Cordeiro's humming frog has been coined for this species. Description The type series consists of two adult males measuring in snout–vent length. The body is ovoid in shape. The snout is short. No tympanum is present. The fingers lack webbing. The hind limbs are robust and the toes have well-developed webbing. Preserved specimens are uniformly dark brown. The lower parts are cream-colored with fine, darker marbling. Males have a small subgular vocal sac. The male advertisement call consists of multi-pulsed notes produced in series lasting 1.3–27 seconds. Each call has 9–182 notes with dominant frequency of 4500–4898 Hz. Habitat an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Amphibians Described In 2003
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 ...

Endemic Frogs Of Brazil
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiasmocleis
''Chiasmocleis'' is a genus of microhylid frogs. They are found in tropical South America north and east of the Andes. Their common name is humming frogs or silent frogs, the latter referring to the formerly recognized ''Syncope''. Taxonomy There has been various attempts to delimit this genus in a way that would make it monophyletic. As of mid 2021, it is recognized as including the former ''Syncope'', but consisting of three clades ranked as subgenera: Of these, ''Relictocleis'' is the most divergent and may even be considered a separate, monotypic genus, with ''Relictocleis gnoma'' as its sole member. Description ''Chiasmocleis'' are small-bodied frogs with small limbs. They are sexually dimorphic, with males having darker chin, abundant to no dermal spines, and variable degree of pedal webbing. Subgenus ''Syncope'' is characterized by size reduction and reduction or loss of phalanges and digits. Also ''Relictocleis'' are particularly small. Ecology ''Chiasmocleis'' are fo ...

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 ...

Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...

Gular Skin
Gular skin (throat skin), in ornithology, is an area of featherless skin on birds that joins the lower mandible of the beak (or ''bill'') to the bird's neck. Other vertebrate taxa may have a comparable anatomical structure that is referred to as either a gular sac, throat sac, vocal sac or gular fold. In birds Gular skin can be very prominent, for example in members of the order Phalacrocoraciformes as well as in pelicans (which likely share a common ancestor). In many species, the gular skin forms a flap, or gular pouch, which is generally used to store fish and other prey while hunting. In cormorants, the gular skin is often colored, contrasting with the otherwise plain black or black-and-white appearance of the bird. This presumably serves some function in social signalling, since the colors become more pronounced in breeding adults. In frigatebirds, the gular skin (or gular sac or throat sac) is used dramatically. During courtship display, the male forces air into the sac, ...

Type Series
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

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] |
