Chamaesaura anguina
The Cape grass lizard (Chamaesaura anguina) is a slender, snake-like lizard found in the grasslands of southern Africa. It is ovoviviparous, meaning its eggs hatch internally, and females can breed year-round, an adaptation likely to mitigate losses from wildfires common in its habitat. The species is recognized by three subspecies and is listed as Near Threatened in Eswatini, though globally categorized as Least Concern by the IUCN.

About Chamaesaura anguina
The Cape Grass Lizard (Chamaesaura anguina)
The Cape grass lizard, scientifically designated as Chamaesaura anguina, is a notable reptile species native to the extensive grasslands of southern Africa. Often referred to by common names such as the Cape snake lizard or highland grass lizard, this species is distinguished by its elongated, serpentine body, which gives it a snake-like appearance.
Habitat and Distribution
Chamaesaura anguina is widely distributed across southern Africa, with confirmed sightings in countries including South Africa, Eswatini, Angola, Kenya, Tanzania, Mozambique, the Republic of the Congo, and Uganda. Its preferred habitat consists of grasslands, environments that are frequently subjected to natural phenomena like wildfires. The resilience and adaptability of the Cape grass lizard are partly explained by its reproductive strategies.
Reproduction and Conservation
This lizard species exhibits ovoviviparity, a mode of reproduction where eggs develop and hatch within the mother's body. A significant discovery regarding its breeding habits is that females can reproduce throughout the year. This continuous reproductive cycle is likely an evolutionary adaptation to mitigate the risks of reproductive failure that could arise from the unpredictable nature of wildfires, which can devastate local populations.
Three distinct subspecies of Chamaesaura anguina have been identified: C. a. anguina, C. a. oligopholis, and C. a. tenuior. While the species is not extensively detailed in broader conservation assessments like the Southern African Red Data, it is listed as Near Threatened in Eswatini. However, on a global scale, the International Union for Conservation of Nature (IUCN) classifies the Cape grass lizard as Least Concern, indicating a stable overall population.
