Draft Genome Assembly Statistics:
Genome Length:
4.53 Gigabases
BUSCO completeness score (single and duplicated genes):
99.6% [Single: 50.6%, Duplicated: 49%]
Importance:
The greater padloper tortoise is endemic to South Africa and contributes to ecosystem stability in the Karoo. As the largest species in the genus Homopus, it is of scientific interest for studies of limb development, as it is one of only two Homopus species with four digits on each foot.

Psammobates tentorius trimeni
Namaqualand tent tortoise

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.
