Psammobates tentorius tentorius

Importance:
The Karoo tent tortoise is an important seed disperser for various plant species and endemic to South Africa. It is arguably one of the most taxonomically confusing and morphologically polymorphic species of Testudines. It is listed as "Near Threatened" by the IUCN and is confined to the central and lower Karoo regions. Remarkably, no genomic studies have been conducted on any tortoise species in Africa or across the entire Southern Hemisphere.
