The '''Viperinae''', or viperines, are a subfamily of [[venomous snake|venomous]] [[Viperidae|viper]]s found in [[Europe]], [[Asia]] and [[Africa]]. They are distinguished by their lack of the heat-sensing pit organs that characterize their sister group, the [[Crotalinae]]. Currently, 12 genera and 66 species are recognized.<ref name="ITIS">{{ITIS|ID=563898|taxon=Viperinae|year=2006|date=4 August}}</ref> Most are tropical and subtropical, although one species, ''[[Vipera berus]]'', even occurs within the [[Arctic Circle]].<ref name="Mal03"/>
'''''Vipera''''' is a [[genus]] of [[venomous snake|venomous]] [[Viperinae|viper]]s. It has a very wide range, being found from from [[North Africa]] to just withing the [[Arctic Circle]] and from the [[British Isles]] to [[Pacific]] [[Asia]].<ref name="Mal03"/> 23 [[species]] are currently recognized.<ref name="ITIS">{{ITIS|ID=202180|taxon=Vipera|year=2006|date=13 August}}</ref>


==Description==
==Description==
Members of this subfamily range in size from ''[[Bitis schneideri]]'', that grows to a maximum of 28 cm, to ''[[Bitis gabonica]]'' that reaches a maximum length of over 2 m. Most species are terrestrial, but a few, such as ''[[Atheris]]'', are completely arboreal.<ref name="Mal03"/>
Members are usually small and more or less stoutly built. The head is distinct from the neck and covered with small scales in many species, although some have a few small plates on top. The dorsal scales are strongly keeled, the anal scale is divided and the subcaudals paired.<ref name="Mal03"/>


Although the heat-sensing pits that characterize the [[Crotalinae]] are clearly lacking in the viperines, a supernasal sac with sensory function has been described in a number of species. This sac is an invagination of the skin between the supranasal and nasal scales and is connected to the ophthalmic branch of the trigeminal nerve. The nerve endings here resemble those in the labial pits of boas. The supernasal sac is present in ''[[Daboia]]'', ''[[Pseudocerastes]]'' and ''[[Causinae|Causus]]'', but is especially well developed in ''[[Bitis]]''. Experiments have shown that strikes are not only guided by visual and chemical cues, but also by heat, with warmer targets being struck more frequently than colder ones.<ref name="Mal03"/>
==Geographic range==
They can be found in [[Great Britain]] and nearly all of continental [[Europe]], on some small islands of the [[Mediterranean]] ([[Elba]], [[Montecristo]], [[Sicily]]) and the [[Aegean Sea]], as well as in [[northern Africa]] in [[Morocco]], [[Algeria]] and [[Tunisia]]. It also occurs across the [[Arctic Circle]] and eastwards though [[northern Asia]] to [[Sakhalin Island]] and northern [[Korea]]. <ref name="McD99"/>


==Geographic range==
==Habitat==
[[Europe]], [[Asia]] and [[Africa]].<ref name="McD99"/> However, they do not occur in [[Madagascar]].<ref name="Sti74">Stidworthy J. 1974. Snakes of the World. Grosset & Dunlap Inc. 160 pp. ISBN 0-448-11856-4.</ref>
Most species prefer cooler environments. Those found at lower latitudes tend to prefer higher altitudes and dryer, rocky habitats, while the species that occur at more northern latitudes prefer lower elevations and environments that have more vegetation and moisture.<ref name="Mal03"/>
 
==Behavior==
All species are [[terrestrial animal |terrestrial]].<ref name="Mal03"/>


==Reproduction==
==Reproduction==
Generally, members of this subfamily are [[viviparous]] ([[Ovoviviparity|ovoviviparous]]), although a few, such as ''[[Pseudocerastes]]'', lay eggs.<ref name="Mal03"/>
All members are [[viviparous]], giving birth to live young.<ref name="Mal03"/>
 
==Venom==
Most ''Vipera'' species have venom that contains both [[Neurotoxin|neurotoxic]] and [[Hemotoxin|hemotoxic]] components. Bites vary widely in severity. Smaller, northern species, such as ''[[Vipera berus|V. berus]]'', have only slightly less toxic venom, but inject very little. Others, such as ''[[Vipera ammodytes|V. ammodytes]]'', are capable of injecting much more with devastating results. However, bites from ''Vipera'' species are rarely as severe as those from larger ''[[Macrovipera]]'' or ''[[Daboia]]''.<ref name="Mal03"/>

* Genus ''Azemiops'' - moved to subfamily ''[[Azemiopinae]]'' by Liem, Marx & Rabb (1971).
* Genus ''Causus'' - recognition of subfamily ''[[Causinae]]'' (Cope, 1860) was proposed by Groombridge (1987) and further supported by Cadle (1992).
 
Nevertheless, these groups, together with the genera currently recognized as belonging to the Viperinae, are still often referred to collectively as the true vipers.<ref name="Mal03"/>

Common names: Palaearctic vipers,[2] Eurasian vipers.[3]


Vipera is a genus of venomous vipers. It has a very wide range, being found from from North Africa to just withing the Arctic Circle and from the British Isles to Pacific Asia.[2] 23 species are currently recognized.[4]

Description

Members are usually small and more or less stoutly built. The head is distinct from the neck and covered with small scales in many species, although some have a few small plates on top. The dorsal scales are strongly keeled, the anal scale is divided and the subcaudals paired.[2]

Geographic range

They can be found in Great Britain and nearly all of continental Europe, on some small islands of the Mediterranean (Elba, Montecristo, Sicily) and the Aegean Sea, as well as in northern Africa in Morocco, Algeria and Tunisia. It also occurs across the Arctic Circle and eastwards though northern Asia to Sakhalin Island and northern Korea. [1]

Habitat

Most species prefer cooler environments. Those found at lower latitudes tend to prefer higher altitudes and dryer, rocky habitats, while the species that occur at more northern latitudes prefer lower elevations and environments that have more vegetation and moisture.[2]

Behavior

All species are terrestrial.[2]

Reproduction

All members are viviparous, giving birth to live young.[2]

Venom

Most Vipera species have venom that contains both neurotoxic and hemotoxic components. Bites vary widely in severity. Smaller, northern species, such as V. berus, have only slightly less toxic venom, but inject very little. Others, such as V. ammodytes, are capable of injecting much more with devastating results. However, bites from Vipera species are rarely as severe as those from larger Macrovipera or Daboia.[2]
