It is found in the Eastern Cape, Free State, Western Cape and Northern Cape
provinces of South Africa.
PromethION Sequencing Report:
Output:
89.36 Gigabases
Approximate N50:
6.51 kilobases
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.

Importance:
The dwarf cushion star is a widespread and ecologically significant intertidal species in South Africa. It contributes to biodiversity by maintaining balance in rocky shore ecosystems and serving as prey and grazer. Sequencing its genome will provide insights into adaptation to harsh intertidal conditions, population connectivity, and resilience to environmental change, supporting conservation and enhancing understanding of echinoderm evolution within South Africa's unique marine biodiversity.
