3: BOOMSLANG ;
Restricted to sub-Saharan Africa, the boomslang (Dispholidus typus) is known as one of the most venomous snakes on the continent. Its venom is haemotoxic, which means that it disables the body’s natural blood-clotting mechanism and triggers uncontrollable external and internal bleeding. The venom is slow-acting, with symptoms taking several hours to present themselves. Because of this, victims sometimes assume that they don’t need treatment, which can increase the severity of the eventual damage. Despite the potency of the boomslang’s bite, human fatalities are rare. This is because boomslangs are typically timid, and flee from humans rather than attacking them. They are tree-dwelling snakes (their name means “tree snake” in Afrikaans). Colouration varies, but males are typically light green with black or blue scale edges, while females are often brown. Boomslangs have exceptionally large eyes and reach an average length of around 5.2 feet/ 1.6 meters.
