There are several animal species in South Africa that are considered critically endangered, meaning they face an extremely high risk of extinction in the wild. Here are a few examples:

1. Black Rhinoceros: The black rhinoceros is one of the most endangered species in Africa, and South Africa is no exception. The species is threatened by habitat loss, poaching for its horn, and other factors.

2. Riverine Rabbit: The riverine rabbit is one of the world’s most endangered mammals, and it is only found in South Africa. Habitat loss and fragmentation, as well as predation by domestic and feral animals, are major threats to this species.

3. Pickersgill’s Reed Frog: This frog species is critically endangered and is only found in a few isolated populations in South Africa. Habitat loss and degradation, as well as invasive species and disease, are major threats to this species.

4. Cape Vulture: The Cape Vulture is a large bird of prey that is only found in Southern Africa, including South Africa. The species is threatened by habitat loss and degradation, electrocution and poisoning, and other factors.

5. Blue Swallow: The Blue Swallow is a small bird species that is found only in a few isolated populations in South Africa. Habitat loss and degradation, as well as pesticide use and other factors, are major threats to this species.
