Lepidobatrachus Laevis
''Lepidobatrachus laevis'', widely known as Budgett's frog, is a species of frog in the family Ceratophryidae, discovered by John Samuel Budgett. It is often kept as a pet. It has acquired a number of popular nicknames, including hippo frog, Freddy Krueger frog, and escuerzo de agua. Description This frog has become popular in pet stores due to its comical flat appearance and intelligent behavior. Females reach a size of while males sometimes only grow half as large. They have a large head that makes up to 1/3 of the body, with a notably large mouth. Their mouth contains a top row of teeth and two "fangs" on the lower jaw. They have extremely short and stubby limbs and the forelimbs are unwebbed. ''L. laevis'' is dark olive green with darker blotches outlined in orange. The males have a dark blue throat. Diet and behavior The wide-mouth frog is well adapted to its environment, notably the harsh winter. During this time it will remain inactive underground in a cocoon of she ...

Budgett's Frog
''Lepidobatrachus'' is a genus of ceratophryidid frogs. They are commonly known as Paraguay horned frogs or Budgett's frogs (in honor of John Samuel Budgett, who described the genus), although the latter technically describes a specific species, '' Lepidobatrachus laevis''. Geographic range ''Lepidobatrachus'' are found in South America, in Paraguay, Argentina, Brazil, and Bolivia. Description ''Lepidobatrachus'' frogs are generally a light, olive green in color, sometimes with lighter green or yellow mottling. They have a rounded, flattened body with eyes set high on their head. They have short limbs, which make them inefficient swimmers. They do not have teeth, but they do have two sharp protrusions, common to all Ceratophryidae The Ceratophryidae, also known as common horned frogs, are a family of frogs found in South America. It is a relatively small family with three extant genera and 12 species. Despite the common name, not all species in the family have the hor ...

John Samuel Budgett
John Samuel Budgett (16 June 1872 – 19 January 1904) was a British zoologist and embryologist. He spent most of his short career on the genus ''Polypterus'' (bichir). This is found in the lakes, river margins, swamps, and floodplains of tropical central and western Africa and the Nile River system. Zoologists at the time wondered whether it was a bony fish, a cartilaginous fish, a lungfish or a primitive amphibian. Forty years after the publication of Darwin’s Origin of Species, zoologists were seeking to map the history of species and this primitive animal was a key part of the map. To find its place there, it was necessary to observe juvenile ''Polypterus'' in the wild. It took Budgett four African expeditions but in the end he succeeded in doing so. However, the long periods spent in swampy, mosquito-ridden places left him debilitated with malaria and he died of blackwater fever shortly after his return to England. This happened on the very day that he was supposed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 tadpoles have ...

Amphibians Of Bolivia
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Gran Chaco
The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland natural region of the Río de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain. Toponymy The name Chaco comes from a word in Quechua, an indigenous language from the Andes and highlands of South America. The Quechua word ''chaqu'' meaning "hunting land" comes probably from the rich variety of animal life present throughout the entire region. Geography The Gran Chaco is about 647,500 km² (250,000 sq mi) in size, though estimates differ. It is located west of the Paraguay River and east of the Andes, and is mostly an alluvial sedimentary plain shared among Paraguay, Bolivia, and Argentina. It stretches from about 17 to 33°S latitude and between 65 and 60°W longitude, though estimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...
