Although mole snakes can give a nasty bite, they are not venomous.
They are powerful constrictors, feeding mainly on golden moles and other rodents.
Mole snakes burrow through sand and spend much of their time underground, but can be seen basking in the sun.
In the south of South Africa mole snakes tend to be black or dark brown, while in the north they are brown, reddish brown, yellow or grey.
Mole snakes hiss loudly and strike when threatened.
