Ptychadenidae
Ptychadenidae is a family of frogs commonly known as the grassland frogs. These frogs occur in Sub-Saharan Africa.

Hildebrandtia (frog)
''Hildebrandtia'' is a genus of frogs in the family Ptychadenidae. They are distributed in tropical and subtropical Sub-Saharan Africa. The common name of this genus is Hildebrandt's burrowing frogs or ornate frogs. The genus name honours Johann Maria Hildebrandt, a German botanist and explorer. Description and ecology ''Hildebrandtia'' are medium-sized to large frogs with stocky bodies. They use their large inner metatarsal tubercles for digging. They live in dry to very dry savanna habitats and stay hidden in their burrows most of the year. Reproduction takes place in temporary ponds and puddles at the beginning of the rainy season. The 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 i ...s are robust-bodied with a muscular tail and low tail fin. They have strong jaws and a ...

Ptychadena
''Ptychadena'' is a genus of frogs in the grassland frog family, Ptychadenidae. They are distributed in Sub-Saharan Africa, as well as nilotic Egypt Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Medit .... The common names of this genus are ridged frogs and grass frogs. This type of family have many different characteristics such as the species, '' Ptychadena neumanni'' who have long hindlimbs and a large ear drum compared to the '' Ptychadena erlangeri, for example.'' They also have a unique bone structure which is a fusion between the presacral vertebrae and sacrum.

Lanzarana
''Lanzarana'' is a genus of frogs in the family Ptychadenidae. It is monotypic, being represented by the singles species, ''Lanzarana largeni'', commonly known as Lanza's frog. ''Lanzarana largeni'' is endemic to Somalia. ''Lanzarana largeni'' breed in temporary pools and small reservoirs. Outside the breeding season their habitats are poorly known but probably are dry 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.

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), 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, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, 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 (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
