Scutiger Spinosus
''Scutiger spinosus'' is a species of toad in the family Megophryidae. It is found in Medog County, Tibet (China) and in Tawang district, Arunachal Pradesh (India). Prior to its description in 2016, it was confused with '' Scutiger nyingchiensis''. Common name spiny lazy toad has been coined for it. Description Adult males measure and adult females in snout–vent length. The body is slightly compressed and the head is large. The snout is rounded. Tympanum is totally absent, but the supratympanic fold is distinct. The forelimbs are long whereas the hindlimbs are moderately short. The finger and the toe tips are rounded; the toes have rudimentary webbing. Skin is dorsally very rough and largely covered with tubercles, many of them bearing black spines. Ventral skin is mostly smooth. The upper surfaces are dark brownish gray; the flanks are light brown. There is a triangular pattern on the head, and the sides of the head are dark brown.

Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture ( folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae (fire-bellied toads and jungle toads) * Calyptocephalellidae ( helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae ( European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae ( American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps ...

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 obje ...

Most are endemic to China. Evolution A 2017 molecular phylogenetic study found that ''Scutiger'' originated in Paleo-Tibet during the Oligocene. Species The following species are recognised in the genus ''Scutiger'': * '' Scutiger adungensis'' Dubois, 1979 – Adung lazy toad * ''Scutiger bhutanensis'' Delorme and Dubois, 2001 * ''Scutiger boulengeri'' (Bedriaga, 1898) – Boulenger's lazy toad, Xizang alpine toad, Himalayan stream frog * '' Scutiger brevipes'' (Liu, 1950) * ''Scutiger chintingensis'' Liu and Hu, 1960 – Chinting lazy toad, Chinting alpine toad * ''Scutiger ghunsa'' Khatiwada, Shu, Subedi, Wang, Ohler, Cannatella, Xie, and Jiang, 2019 – Ghunsa high altitude toad * '' Scutiger glandulatus'' (Liu, 1950) – Hopachai lazy toad, chest gland cat-eyed toa ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpol ...

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 ...

Megophryidae
Megophryidae, commonly known as goose frogs, is a large family of frogs native to the warm southeast of Asia, from the Himalayan foothills eastwards, south to Indonesia and the Greater Sunda Islands in Maritime Southeast Asia, and extending to the Philippines. Fossil remains are also known from North America. it encompasses 246 species of frogs divided between five genera. For lack of a better vernacular name, they are commonly called megophryids. Morphology The megophryids are notable for their camouflage, especially those that live in forests, which often look like dead leaves. The camouflage is accurate to the point of some having skin folds that look like leaf veins, and at least one species, the long-nosed horned frog (''Megophrys montana'') has sharp projections extending past the eye and nose, which disguise the frog shape. Megophryids range in size from in length. The adults' tongues are noticeably paddle-shaped. Their tadpoles can be found in a variety of waters, but ...

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 wo ...
