Psammobates tentorius trimeni

Namaqualand tent tortoise

Species Card Details

Importance:

The Namaqualand tent tortoise is a vibrant and highly polymorphic seed disperser. Widely regarded as the most colourful tortoise in the world, it has a more restricted range than other tent tortoise species. Listed as “Near Threatened” by the IUCN, it faces pressures from habitat loss, the illegal pet trade, and increasing aridity. No genomic studies have been conducted on any tortoise species in Africa or the Southern Hemisphere.
