Pit Viper
The Crotalinae, commonly known as pit vipers,Mehrtens JM (1987). ''Living Snakes of the World in Color''. New York: Sterling Publishers. 480 pp. . crotaline snakes (from grc, κρόταλον ''krotalon'' castanet), or pit adders, are a subfamily of vipers found in Eurasia and the Americas. Like all other vipers, they are venomous. They are distinguished by the presence of a heat-sensing pit organ located between the eye and the nostril on both sides of the head. Currently, 23 genera and 155 species are recognized: These are also the only viperids found in the Americas. The groups of snakes represented here include rattlesnakes, lanceheads, and Asian pit vipers. The type genus for this subfamily is ''Crotalus'', of which the type species is the timber rattlesnake, ''C. horridus''. These snakes range in size from the diminutive hump-nosed viper, ''Hypnale hypnale'', that grows to a typical total length (including tail) of only , to the bushmaster, ''Lachesis muta'', a specie ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viperidae
The Viperidae (vipers) are a family of snakes found in most parts of the world, except for Antarctica, Australia, Hawaii, Madagascar, and various other isolated islands. They are venomous and have long (relative to non-vipers), hinged fangs that permit deep penetration and injection of their venom. Four subfamilies are currently recognized. They are also known as viperids. The name "viper" is derived from the Latin word ''vipera'', -''ae'', also meaning viper, possibly from ''vivus'' ("living") and ''parere'' ("to beget"), referring to the trait viviparity (giving live birth) common in vipers like most of the species of Boidae. Description All viperids have a pair of relatively long solenoglyphous (hollow) fangs that are used to inject venom from glands located towards the rear of the upper jaws, just behind the eyes. Each of the two fangs is at the front of the mouth on a short maxillary bone that can rotate back and forth. When not in use, the fangs fold back against the ro ...

Auguste Duméril
Auguste Henri André Duméril (30 November 1812 – 12 November 1870) was a French zoologist. His father, André Marie Constant Duméril (1774-1860), was also a zoologist. In 1869 he was elected as a member of the Académie des sciences. Duméril studied at the University of Paris, and in 1844 became an associate professor of comparative physiology at the university. From 1857, he was a professor of herpetology and ichthyology at the Muséum National d'Histoire Naturelle in Paris. In 1851, with his father, he published ''Catalogue méthodique de la collection des Reptiles''. With zoologist Marie Firmin Bocourt (1819–1904), he collaborated on a project called ''Mission scientifique au Mexique et dans l'Amérique Centrale'', a publication that was the result of Bocourt's scientific expedition to Mexico and Central America from 1864 to 1866. The section on reptiles is considered to be Dumeril's best written effort in the field of herpetology. Duméril died in 1870 during the sieg ...

Gabriel Bibron
Gabriel Bibron (20 October 1805 – 27 March 1848) was a French zoologist and herpetologist. He was born in Paris. The son of an employee of the Museum national d'histoire naturelle, he had a good foundation in natural history and was hired to collect vertebrates in Italy and Sicily. Under the direction of Jean Baptiste Bory de Saint-Vincent (1778–1846), he took part in the Morea expedition to Peloponnese. He classified numerous reptile species with André Marie Constant Duméril (1774–1860), whom he had met in 1832. Duméril was interested mainly in the relations between genera, and he left to Bibron the task of describing the species. Working together they produced the ''Erpétologie Générale'', a comprehensive account of the reptiles, published in ten volumes from 1834 to 1854. Also, Bibron assisted Duméril with teaching duties at the museum and was an instructor at a primary school in Paris. Bibron contracted tuberculosis and retired in 1845 to Saint-A ...
