Africa's most venomous snake. Not to be confused with Africa's most dangerous snake - that title rightly belongs to the fearsome Black Mamba.
The Boomslang (African Tree Snake) - you need slightly less venom to kill a man than the Black Mamba but you are far less likely to be bitten by a Boomslang than a Black Mamba.
This Boomslang in the picture is bleeding as it was being attacked by a bird - a Grey Headed Shrike. This is quite ironic as the Boomslang includes birds in it's diet!
The Boomslangs other prey are lizards, chameleons in particular.
Boomslang come in various color variations:
Brown are often females
Green and black are often males
