A number of reptiles and amphibians occur on the reserve. Clicking stream frogs and painted reed frogs call in large numbers at water bodies in the late afternoon and early evening. Tortoises are often seen; in the summer months – the angulate tortoise is abundant. Few venomous snakes occur, but one of them, the puff adder, is common. The spotted gecko is also widespread, sheltering in old giant land-snail shells.

Common or Rhombic Eggeater (Dasypeltis scabra)
  • A common snake known to occur throughout southern Africa - however, it is seldom seen
  • Egg eating snakes have several adaptations of the head and jaws - make it possible for them to eat eggs of up to three time the diameter of their heads 
  • Special teeth in the gullet saw through the shell as it is being swallowed, allowing the liquid part of the egg to be extracted

  • Upper lip is reddish or orange for animals in the southern part of its range
  • It will rear up and flatten its neck when provoked - causes it to be confused with cobras or vipers
  • Although its bite will bleed profusely, the venom has little effect on humans
  • Its normal prey, mainly frogs, are not so lucky and will succumb quickly once bitten
Boomslang (Dispholidus typus)

  • The venom is cytotoxic and is usually deeply injected
  • About 60% of serious bites in Southern Africa are caused by Puffadders - responsible for most of the fatalities
