Afrixalus Osorioi
''Afrixalus osorioi'' is a species of frog in the family Hyperoliidae. It is found in Angola, Democratic Republic of the Congo, Gabon, western Kenya, and Uganda. The specific name ''osorioi'' honours Balthazar Osório, a Portuguese ichthyologist. Its common names include Angola banana frog, Osorio's spiny reed frog, Congro spiny reed frog, and forest tree frog. Description Adult males measure around and adult females in snout–vent length. They have a light and dark brown dorsal pattern that normally include a rectangular dark dorsal spot and which extends to the anus. Males have small, scattered, and inconspicuous asperities on the dorsal surfaces of head, body, and limbs. The tibia The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects ... have light upper side.

Raymond Laurent
Raymond Ferdinand Louis-Philippe Laurent (16 May 1917 – 3 February 2005) was a Belgian herpetologist, who specialized in African and South American amphibians and reptiles. He published more than 200 scientific articles and book chapters. Several species In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of ... have been named after him, most recently '' Phymaturus laurenti'' in 2010. Additional species of reptiles named in his honor include '' Chironius laurenti'', '' Liolaemus laurenti'', and '' Mehelya laurenti''.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).

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 ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

Tibia
The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute '' tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The ossification or formation of the bo ...

Sexual Selection In Amphibians
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour *Animal sexual behaviour **Copulation (zoology) **Human sexual activity ** Non-penetrative sex, or sexual outercourse ** Sex drive, a person's overall sexual drive or desire for sexual activity ** Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species *Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization **Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainme ...

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 Angola
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 dramat ...
