There are two species of snakes in the genus ๐๐ด๐ข๐ฎ๐ฎ๐ฐ๐ฑ๐ฉ๐บ๐ญ๐ข๐น in South Africa that are well-known by the unfortunate name โskaapstekerโ (Afrikaans word meaning sheep-stabber). However, both species have relatively small fangs set extremely far back in their jaw, and mild neurotoxic venom that poses little threat to large animals (the venom is often considered harmless to humans). It is therefore extremely unlikely that they have ever killed a sheep. However, they are abundant grassland species that may be found in the vicinity before or after a sheep is found dead from snakebite. The culprit is likely to be a highly venomous species such as a Cape Cobra (๐๐ข๐ซ๐ข ๐ฏ๐ช๐ท๐ฆ๐ข) or Puff Adder (๐๐ช๐ต๐ช๐ด ๐ข๐ณ๐ช๐ฆ๐ต๐ข๐ฏ๐ด). And unfortunately for both of our โskaapstekersโ, the name has brought with it a prejudice that often sees them killed on sight, supposedly to protect livestock despite their inability to harm these animals.
It is therefore more responsible to use a better name for these snakes than โskaapstekerโ. Two of the six species in this genus occur in South Africa, namely the Spotted Grass Snake (๐๐ด๐ข๐ฎ๐ฎ๐ฐ๐ฑ๐ฉ๐บ๐ญ๐ข๐น ๐ณ๐ฉ๐ฐ๐ฎ๐ฃ๐ฆ๐ข๐ต๐ถ๐ด) and the Striped Grass Snake (๐๐ด๐ข๐ฎ๐ฎ๐ฐ๐ฑ๐ฉ๐บ๐ญ๐ข๐น ๐ต๐ณ๐ช๐ต๐ข๐ฆ๐ฏ๐ช๐ข๐ต๐ถ๐ด). The Spotted Grass Snake is found in South Africa, Swaziland, Lesotho and Namibia. In South Africa it is found in all nine provinces, though it is absent from much of North West Province, western Free State, and central and eastern Northern Cape. In contrast, the Striped Grass Snake is found more widely and its range extends from Tanzania to Angola, western Mozambique, Zimbabwe, Botswana, Namibia and South Africa. The South African distribution is restricted to Limpopo, Mpumalanga, Gauteng, North-West Province and western Free State. Adult grass snakes feed on rodents, nestling birds, frogs, other snakes and lizards. The Spotted Grass Snake is one of very few snake species where the female coils around and protects her eggs.
Although the two species were re-named Spotted and Striped Grass Snake in the ๐๐ต๐ญ๐ข๐ด ๐ข๐ฏ๐ฅ ๐๐ฆ๐ฅ ๐๐ช๐ด๐ต ๐ฐ๐ง ๐ต๐ฉ๐ฆ ๐๐ฆ๐ฑ๐ต๐ช๐ญ๐ฆ๐ด ๐ฐ๐ง ๐๐ฐ๐ถ๐ต๐ฉ ๐๐ง๐ณ๐ช๐ค๐ข, ๐๐ฆ๐ด๐ฐ๐ต๐ฉ๐ฐ ๐ข๐ฏ๐ฅ ๐๐ธ๐ข๐ป๐ช๐ญ๐ข๐ฏ๐ฅ (2014), the adoption of the name โGrass Snakeโ has been met with resistance by some members of the general public and even by some herpetologists, despite the obvious mis-information in the name. We strongly recommend the use of the name โgrass snakeโ to combat the spread of mis-information that leads to stigma.
If you spot a grass snake or other reptile or amphibian in the Free State, we would love to add a photo of it to our records! Please join us on Free State Reptiles and Amphibians (including adjacent areas and Lesotho) at https://www.facebook.com/groups/FreeStateHerps
