  Analytical - Venoms database   (Site not responding. Last check: 2007-10-21)
This new nomenclature should facilitate classification and reduce confusion.
The database covers all snakes of the Atractaspididae, Azemiopinae, Crotalidae, Elapidae, Hydrophiidae and Viperidae families.
As regards Colubridae, we chose a broad view of the notion of "venomous": any time we were aware of a described case of envenomation, we usually included all species of the corresponding genus.

The Xenoderminae, Viperidae, Pareatinae, Psammophiinae, Pseudoxyrophiinae, Homalopsinae, Natricinae, Xenodontinae, and Colubrinae (redefined) emerged monophyletic, whilst Lamprophiinae, Atractaspididae, and Elapidae were non-monophyletic in one or more topologies.
A clade comprising Acrochordus and Xenoderminae branched closest to the root, and when Acrochordus was assessed in relation to a colubroid subsample and all five non-caenophidians, it remained associated with the Colubroidea.
Other relationships appearing in all final topologies were: 1) a clade comprising Psammophiinae, Lamprophiinae, Atractaspididae, Pseudoxyrophiinae, and Elapidae, within which the latter four taxa formed a subclade; 2) a clade comprising Colubrinae, Natricinae, and Xenodontinae, within which the latter two taxa formed a subclade.

Colubroids or advanced snakes form a monophyletic group comprising four families: Atractaspididae (11 genera, 70 species), Colubridae (300 genera, 1850 species), Elapidae (65 genera, 270 species) and Viperidae (33 genera, 240 species).
The front-fanged venom system (displayed by some Atractaspididae, all Elapidae and all Viperidae) evolved several times independently and appeared early within colubroids.
The rear-fanged venom system (displayed by some Atractaspididae and many Colubridae) has been studied less than the front-fanged system, although it is clear that opisthoglyph Colubridae constitute a polyphyletic group.

CJO - Abstract - Atractaspis (Serpentes, Atractaspididae) the burrowing asp; a multidisciplinary minireview
The family Atractaspididae is a highly modified derivative of a lineage that apparently arose early in the history of ‘colubroid’ snakes, and its taxonomy and relationship with other ophidian groups is still uncertain.
Snakes of the genus Atractaspis have a characteristic venom apparatus, including the structure and function of the striking unit and of the venom glands.

 Ophitoxaemia - venomous snake bite
Based on their morphological characteristics including arrangement of scales, dentition, osteology, myology, sensory organs etc., snakes are categorized into families.
The families of venomous snakes are Atractaspididae, Elapidae, Hydrophidae and Viperidae.
The major families in the Indian subcontinent are: Elapidae which includes common cobra, king cobra and krait, Viperidae which includes Russell's viper, pit viper and saw-scaled viper and Hydrophidae (the sea snakes) [1].

Snakes may be divided initially into two groups, the so-called "primitive" snakes, the Boidae (boas and pythons), and the "advanced" snakes which include the Elapidae, the Colubridae and Viperidae.
Amongst the advanced snakes, only the Viperidae, Atractaspididae and Elapidae are front-fanged.
Most of the Colubridae are rear-fanged snakes, which have a venom gland producing toxins which are delivered near the base of the teeth at the back of the upper jaw.

 WCH Clinical Toxinology Resources
Our databases cover all species of snakes in the venomous families Elapidae, Viperidae and Atractaspididae and selected species from Colubridae.
We use the most recent taxonomy available to us, therefore if you use an old scientific name you may not find the species you are looking for.
If you search on Region "Australia" instead, the list will be incomplete, because it will return only those species found exclusively in Australia.
