Johann Gustav Fischer
Johann Gustav Fischer (1 March 1819, Hamburg – 27 January 1889) was a German herpetologist. He served as an instructor at the Johanneum in Hamburg, and was associated with the city's ''Naturhistorisches Museum'', working extensively with its herpetological and ichthyological collections. He was the binomial author of numerous herpetological species, and has several species named in his honor: *"Fischer's cat snake" (''Toxicodryas pulverulenta''), 1856. *"Fischer's chameleon" (''Kinyongia fischeri)'', described by Anton Reichenow in 1887. *"Fischer's dwarf gecko" (''Lygodactylus fischeri)'', described by George Albert Boulenger in 1890. *"Fischer’s snail-eating snake" ('' Tropidodipsas fischeri)'', described by George Albert Boulenger in 1894. *"Fischer's thick-toed gecko" ('' Pachydactylus laevigatus''), 1888. In the field of ichthyology, he described the genera ''Sclerocottus'' (Cottidae) and ''Gymnelichthys'' (Zoarcidae). Published works Many of his scientific papers wer ...

Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus '' Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus '' Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

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 opi ...

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 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 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 grouped with the definition of MENA (i.e. Middle East–North Africa) as it is part o ...

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 the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Hallowell (herpetologist)
Edward Hallowell (1808 – February 20, 1860) was an American herpetologist and physician. He studied and practiced medicine in Philadelphia. He also was a renowned herpetologist who described 61 new species of reptiles. In 1851, Hallowell was elected as a member of the American Philosophical Society. Hallowell is commemorated in the scientific names of two species of frogs: ''Hyla hallowellii'' and ''Leptodactylus hallowelli ''Leptodactylus'' is a genus of leptodactylid frogs. It includes the species commonly called ditch frogs or white-lipped frogs. It is very similar to ''Physalaemus'', a close relative, and indeed the recently described ''Leptodactylus lauramiria ....
