Daboia
''Daboia'' is a genus of venomous vipers.. Species The following four species are recognized as being valid: *''Daboia mauritanica'' – Moorish viper *''Daboia palaestinae'' – Palestine viper *''Daboia russelii'' – Russell's viper *''Daboia siamensis'' – eastern Russell's viper In the future, more species may be added to ''Daboia''. Obst (1983) reviewed the genus and suggested that it be extended to include ''Macrovipera lebetina'', ''Daboia palaestinae'', and '' M. xanthina''. Groombridge (1980, 1986) united ''V. palaestinae'' and ''Daboia'' as a clade based on a number of shared apomorphies In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have ..., including snout shape and head color pattern. Lenk et al.

Daboia Russelii
Russell's viper (''Daboia russelii''), is a venomous snake in the family Viperidae native to the Indian subcontinent and one of the big four snakes in India. It was described in 1797 by George Shaw and Frederick Polydore Nodder, and named after Patrick Russell, who wrote about it in his 1796 work ''An account of Indian serpents, collected on the coast of Coromandel''. Taxonomy English naturalist George Shaw—with illustrator Frederick Polydore Nodder—in ''The Naturalist's Miscellany: Or, Coloured Figures Of Natural Objects; Drawn and Described Immediately From Nature'' formally described the species in 1797 as ''Coluber russelii'', from a specimen presented to the British Museum by Scottish herpetologist Patrick Russell. Russell had written of the species in his 1796 work ''An account of Indian serpents, collected on the coast of Coromandel'', confirming its highly venomous nature by experimenting on chickens and dogs. He added the native people called it ''katuka retula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Venomous Snake
Venomous snakes are Species (biology), species of the Suborder (biology), suborder Snake, Serpentes that are capable of producing Snake venom, venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the Family (biology), families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolu ...

Viperinae
The Viperinae, or viperines, are a subfamily of vipers endemic to Europe, Asia and Africa. They are distinguished by their lack of the heat-sensing pit organs that characterize their sister group, the subfamily Crotalinae. Currently, 13 genera are recognized. Most are tropical and subtropical, although one species, ''Vipera berus'', even occurs within the Arctic Circle. Like all vipers, they are venomous. The common names "pitless vipers", "true vipers", "Old World vipers",Mallow D, Ludwig D, Nilson G. 2003. ''True Vipers: Natural History and Toxinology of Old World Vipers''.

Franz Werner
Franz Josef Maria Werner (15 August 1867 in Vienna – 28 February 1939 in Vienna) was an Austrian zoologist and explorer. Specializing as a herpetologist and entomologist, Werner described numerous species and other taxa of frogs, snakes, insects, and other organisms. His father introduced him at age six to reptiles and amphibians. A brilliant student, he corresponded often with George Albert Boulenger (1858–1937) and Oskar Boettger (1844–1910) who encouraged his studies with these animals. Werner obtained his doctorate in Vienna in 1890 and then after spending a year in Leipzig, began to teach at the Vienna Institute of Zoology. In 1919, he became tenured as a professor, maintaining this title until his retirement in 1933. Although working close to the Vienna Natural History Museum, he could not use their herpetological collections, after the death of its director, Franz Steindachner (1834–1919), who did not like Werner, and had barred him from accessing the collec ...
