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 ...

Colubridae
Colubridae (, commonly known as colubrids , from , 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest fossil species of the family date back to the Late Eocene epoch, with earlier origins suspected. Colubrid snakes are found on every continent except Antarctica. Description Colubrids are a very diverse group of snakes. They can exhibit many different body styles, body sizes, colors, and patterns. They can also live in many different types of habitats including aquatic, terrestrial, semi-arboreal, arboreal, desert, mountainous forests, semi-fossorial, and brackish waters. A primarily shy and harmless group of snakes, the vast majority of colubrids are not venomous, nor do most colubrids produce venom that is medically significant to mammals. However, the bites of some can escalate quickly to emergency situations. Furthermore, within the Colubridae, the South African boomslang and twig snakes, as well as the Asian keelback snakes (' ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Sub-Saharan Africa
Sub-Saharan Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West 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 geoscheme for Africa, United Nations (UN). This is considered a non-standardised geographical region with the number of countries included varying from 46 to 48 depending on the organisation describing the region (e.g. United Nations, UN, World Health Organization, WHO, World Bank, etc.). The Regions of the African Union, African Union (AU) uses a different regional breakdown, recognising all 55 member states on the continent—grouping them into five distinct and standard regions.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
