The Egg Eating Snake (Dasypeltis fasciata, medici and scabra) must be one of the nicest snakes we have ever come across. With no teeth, a calm nature and eating purely on eggs, means no more defrosting them rodents!
These are a great species to keep if you are scared of being bitten. The mouth contains no teeth, although some will try and imitate venomous snakes by biting viciously. When they do this, they don't even break the skin! Feeding on fresh eggs.
