AlÃpio De Miranda Ribeiro
AlÃpio Duarte Brandão (born 7 June 1992), known simply as AlÃpio, is a Brazilian footballer who plays for Figueirense as an attacking midfielder. Early years Born in BrasÃlia, Brazilian Federal District, AlÃpio left Brazil at the age of 14. An orphan, he moved to Portugal with his legal guardian Helber Damião, co-owner of the football school ''Dois Toques''. His first footballing rights were split between Damião, his original club in his homeland, Sport Club Internacional, and the team to where he moved, Rio Ave FC. Club career In November 2008, AlÃpio joined Real Madrid for roughly €1.4 million, without having made one single first-team appearance with Rio Ave. He scored two goals on his debut for the C-team which operated in Tercera División, and played his second game against CF Rayo Majadahonda in a 2–0 home win, as they eventually finished in eighth position; he played most of his first two years, however, with the ''Juvenil'' side.

Melanophryniscus Montevidensis
''Melanophryniscus montevidensis'', also called Darwin's toad, is a species of toad in the family Bufonidae and the genus Melanophryniscus found in Brazil and Uruguay. Like other amphibians in its genus, its bright colors, defensive behavior, and rapid metamorphosis make it stand out. It also has a myriad of chemical compounds on its skin that could be used in biomedical applications.Langone, José A. (Mayo 2002). Melanophryniscus, interesantes sapitos uruguayos». ''MUSEO NACIONAL DE HISTORIA NATURAL Y ANTROPOLOGIA'' (4). Consultado el 2023-06-22. Darwin's toad is jet black with yellow patches on its back, sides, forelimbs, and ventral. It has a red spot on the ventral side of the thigh and part of the abdomen. The palms of his hands and soles of its feet are also red. Habitat and Behavior The Darwin's toad's natural habitats are temperate shrubland, intermittent freshwater marshes, and sandy shores.

Taxa Named By AlÃpio De Miranda-Ribeiro
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Of Paraguay
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 ...

Unkenreflex
Unkenreflex – interchangeably referred to as unken reflex (''Unke'' is the German word for the genus of fire-bellied toads) – is a defensive posture adopted by several branches of the amphibian class – including salamanders, toads, and certain species of frogs. Implemented most often in the face of an imminent attack by a predator, unkenreflex is characterized by the subject’s contortion or arching of its body to reveal previously hidden bright colors of the ventral side, tail, or inner limb; the subject remains immobile while in unkenreflex. During the course of unkenreflex, the amphibian in question releases bufotoxins from its parotid glands, tenses its entire body, and swallows air to bloat itself in an attempt to look larger. These secretions, along with the Aposematism, aposematic coloring common among the amphibians which display unkenreflex, serve as a warning to nearby predators that the amphibian may be poisonous. Not all amphibians which display unkenreflexes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 on the skin ...
