Afrixalus Crotalus
''Afrixalus crotalus'' is a species of frogs in the family Hyperoliidae. It is found in southern Malawi, central Mozambique, and eastern Zimbabwe. It might be a subspecies of ''Afrixalus aureus'', a position adopted by the AmphibiaWeb. It is sometimes known as the Zimbabwe banana frog or snoring spiny reed frog. Description Adult males measure and females in snout–vent length. The snout is tapering. The gular disc is large and usually has small asperities. There are also minute asperities on the head; otherwise, the body has no asperities. Adults usually have a rudimentary mid-dorsal line and para-dorsal stripes. The headspot, usually present among the related species, is very weakly developed. Habitat and conservation ''Afrixalus crotalus'' inhabit moist savanna and shrubland at low to medium altitudes. Breeding takes place in ephemeral grassy pools, flooded grassland, and marshes. The eggs are laid in folded, glued leaves of vegetation at, and just under, the surface of wat ...

Frog
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the 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 dating suggests their split from other amphibians may extend further back to the Permian, 265 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 or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs ...

Hyperoliidae
The Hyperoliidae, or sedge frogs and bush frogs, are a large family of small to medium-sized, brightly colored frogs which contains more than 250 species in 19 genera. Seventeen genera are native to sub-Saharan Africa. In addition, the monotypic genus '' Tachycnemis'' occurs on the Seychelles Islands, and the genus '' Heterixalus'' (currently 10 species) is endemic to Madagascar. Hyperoliids range from in body length. Many species have smooth, brightly patterned skin that almost looks enameled. Most hyperoliids are arboreal, but some are terrestrial, including several '' Kassina'' species that move by walking or running rather than hopping. Diets vary widely, with examples including '' Paracassina'', which specializes on snails, and ''Afrixalus fornasini'', the only terrestrial frog known to prey on eggs of other species of anurans. Breeding in this family begins at the start of the rainy season, where hyperoliids congregate at breeding sites. Most hyperoliids lay their eggs ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrixalus Aureus
The golden banana frog, golden dwarf reed frog, golden spiny reed frog, or golden leaf-folding frog (''Afrixalus aureus'') is a species of frog in the family Hyperoliidae. It is found in lowland coastal plains of eastern South Africa (Mpumalanga and northern KwaZulu-Natal), Eswatini, and southern Mozambique. The AmphibiaWeb includes ''Afrixalus crotalus'' in this species as a subspecies, whereas the Amphibian Species of the World and the IUCN Red List of Threatened Species treat ''A. crotalus'' as a full species. Description Adult males measure and females in snout–vent length. Newly metamorphosed froglets measure about . The snout is tapering. Dorsal asperities are usually strongly developed, while the chest and belly are without asperities. The gular disc is large and granulated. The dorsum varies from light brown to intense golden yellow, with light brown to almost black lumbar patches markings and moderately defined bands along the flanks. The venter is whitish.

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrixalus
''Afrixalus'', commonly known as the banana frogs, spiny reed frogs, cat's eye reed frogs, or leaf-folding frogs, is a genus of frog in the family Hyperoliidae. They occur in the Subsaharan Africa. They lay their eggs in vegetation above water, often folding leaves around the eggs for protection—hence the common name "leaf-folding frogs". Species The following species are recognised in the genus ''Afrixalus '': The AmphibiaWeb lists 31 species. It does not include '' Afrixalus "quadrivittatus"'', and does not recognize ''Afrixalus brachycnemis The lesser banana frog (''Afrixalus brachycnemis'') is a species of frog in the family Hyperoliidae.

Frogs Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Amphibians Of Malawi
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 de ...
