Spotted something wrong?

The boomslang, also known as the Cape tree snake, is a species of alethinophidian snake of the family Colubridae. Its name means "tree snake" in Afrikaans and Dutch. It is relatively large, at 1 to 1.50 m in length. It is widely distributed across sub-Saharan Africa, and has different colour phases depending on the area. Males are more colourful than females, and the feature they share is that they have the largest eye of any snake, which is also a bright green that is very striking in young individuals.

Fun facts

  • GeneralA tree snake with a very potent haemotoxic venom and enormous eyes for hunting chameleons.
  • In 1957 the herpetologist Karl Schmidt was bitten by a juvenile boomslang and, convinced that the dose was harmless, meticulously noted his symptoms hour by hour for twenty-four hours until he died: his diary completely changed the medical view of this species.
  • Its venom acts slowly and without initial pain, which has led victims not to seek medical help in time: it can take more than a day to show its full effects.
  • It has the largest eyes in proportion to the head of almost any African colubrid, with excellent binocular vision for hunting chameleons and birds in the canopy.
