Here's something very interesting for the back-fanged lovers !
These are very rare in South Africa collections and it's a pity, as they are amazing snakes to work with.
Malpolon sp. are rear-fanged desert snakes that occur in Northern Africa through to Spain and France (If my memory serves me well). They are fast moving, active snakes that can tolerate high temperatures. Some (most) are highly aggressive and will not hesitate to bite. They get their common name from their ability to spread a hood in defence, just like a cobra.
If you want to know more about these feel free to ask.
ENJOY...
