Rhombic Egg Eater Dasypeltis scabra is a common but easily overlooked snake in northern Botswana. The colouration mimics the venomous night adder and the rough scales when rubbed together in the special coiling motion make a hiss similar to the highly venomous adders. To add to the display the inside of the mouth is pitch-black (a trait it shares with the Black Mamba). However this snake is completely harmless and has no real teeth in it’s mouth. The diet is strictly birds eggs that are broken in the throat by an “egg-tooth” which is a bony protrusion from the spine.
