Group:
Reptile
Estimated genome size:
10 - 20 cm (total body length)
Size:
10 - 20 cm (total body length)
Distribution:
Endemic to the Republic of South Africa, occurring in Little Namaqualand from Port Nolloth to Clanwilliam.
PromethION Sequencing Report:
Output:
48.66 Gigabases
Approximate N50:
5.93 kilobases
Draft Genome Assembly Statistics:
Genome Length:
1.56 Gigabases
BUSCO completeness score (single and duplicated genes):
98.8% [S: 96.9%, D: 2.0%]
Importance:
It serves as an important model species for studying specific stages of limb development within the genus Scelotes, representing an intermediate limb development stage (forelimb digits = 0; hindlimb digits = 2), and for investigating the genomic evolution of vertebrates. It has a restricted distribution and occurs in distinct habitats and regions, making it an excellent model species for biogeographic and molecular ecology studies.

Labeo molybdinus
Leaden labeo
Importance:
The Leaden Labeo is a freshwater fish endemic to Southern Africa. To fully understand its phylogenetic relationships and the evolutionary history and diversification of the Labeo genus in Africa, comprehensive genomic data are crucial. Currently listed as Least Concern on the IUCN Red List, the Leaden Labeo is experiencing population declines due to a range of documented threats. It is occasionally targeted in recreational angling and plays a significant role in subsistence fisheries.
