Green Snakes of the Eastern Cape

This list includes all the green snakes that can be found in the Eastern Cape. Barring the boomslang (Dispholidus typus) and the many-spotted reed snake (Amplorhinus multimaculatus), all the individuals listed come from the genus Philothamnus and they are all closely related.  In the Eastern Cape, the boomslang  is not uniform green. Females are olive and males are green/yellow with black barring. Irrespective of this, the boomslang has been included at the end of the list.

Danger to man: None, it has no venom.

Similar species: This snake is easily confused with all members of the Philothamnus genus (green snakes).

Danger to man: None, it has no venom.

Similar species: This snake is easily confused with all members of the Philothamnus genus (green snakes).

There is considerable colour variation in this species with colour ranging from olive/brown with spots and mottling to uniform green.

Diet: Frogs and toads.

Danger to man: Mildly venomous, but venom is of consequence to humans.

Similar species: This snake is easily confused with all members of the Philothamnus genus (green snakes).

Boomslang (Dispholidus typus typus)

IMG_7015

Size: 1.2-1.5m.

Habits: Diurnal snakes which are found in a large variety of habitats, most commonly in trees and shrubs, but may descend to the floor to bask or find food.

Diet: Chameleons, frogs, tree-living lizards, birds and occasionally rodents.

Danger to man: The boomslang possesses a very dangerous haemotoxic venom capable of killing people. Monovalent antivenom is however available and has been found to be very effective in counteracting the venom. Although dangerous, the snake rarely bites, with most bites being received from snake handlers. There is a big misconception that boomslangs cannot inject venom on larger body parts because they are back-fanged. This is however untrue as boomslangs can open their mouth’s 170 degrees and can thus easily inject venom into a leg or an arm. Due to the placid and shy nature of this snake, there is virtually no chance of simply walking past a tree and being bitten.

Similar species: Boomslangs are easily confused with green mambas and members of the genus Philothamnus (green snakes) north of the Transkei because of the uniform green colour but in eastern Cape males tend to be more of a fluorescent green and females tend to be brown.
