Rhinella Pombali
''Rhinella pombali'' is a hybrid species of toad from south-eastern Brazil, named after José Perez Pombal Jr., a Brazilian herpetologist. It was originally described in 2004 as a distinct species, but a genetic study published in 2012 found it to be a hybrid of ''Rhinella ornata ''Rhinella ornata'' is a species of toad in the family Bufonidae that is found in Brazil and possibly Argentina. Its natural habitats are subtropical or tropical moist lowland forests, rivers, and intermittent freshwater lakes. It is threatened b ...'' and '' Rhinella crucifer''; it is also morphologically intermediate between these species. It is therefore no longer considered a valid species, although it is still present in some listings.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinella Ornata
''Rhinella ornata'' is a species of toad in the family Bufonidae that is found in Brazil and possibly Argentina. Its natural habitats are subtropical or tropical moist lowland forests, rivers, and intermittent freshwater lakes. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... ''Rhinella ornata'' will mate with a sister species, ''Rhinella crucifer'', to form the hybrid species '' Rhinella pombali''.

Rhinella Crucifer
''Rhinella crucifer'' is a species of toad in the family Bufonidae. It endemic to Brazil and known from the Atlantic Forest of eastern Brazil between the states of Ceará in the north and Rio de Janeiro in the south. Common name striped toad has been coined for it. "''Rhinella pombali''" is a hybrid between ''Rhinella ornata'' and this species. Description Adult males measure and adult females in snout–vent length. The head is wide and the snout is rounded to mucronate in dorsal view and rounded in lateral view. The tympanum is distinct. The body is robust. The parotoid glands are elliptical to triangular and overhanging the lateral edges of body. The forelimbs are long and comparatively more robust than the hind limbs. The fingers have no webbing but are slightly fringed. The toes are long and webbed. Dorsal coloration is uniformly ochre, olive, brownish, or silvery. A thin, light vertebral line may be present. Habitat and conservation This species occurs in rainforests a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinella
''Rhinella'', commonly known as South American toads, beaked toads or Rio Viejo toads, is a genus of true toads native to Neotropical parts of Mexico, Central and South America. Additionally, the cane toad has been introduced to Australia, the Caribbean, the Philippines and elsewhere. Originally, all species of the genus ''Rhinella'' were included in the genus ''Bufo'', then they were split into the genera ''Chaunus'' and ''Rhamphophryne''. However, ''Chaunus'' and ''Rhamphophryne'' are now considered synonyms of ''Rhinella''. Etymology * ''Rhinella'' means ‘little nose’, from ''rhino- This is a list of common affixes used when scientifically naming species, particularly extinct species for whom only their scientific names are used, along with their derivations. *a-, an-: ''Pronunciation'': /ə/, /a/, /ən/, /an/.

Amphibians Described In 2004
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 ...
