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 rosae
Rednose labeo
Importance:
The Rednose labeo is a freshwater fish endemic to Southern Africa. Preliminary unpublished short DNA sequence data suggest additional taxonomic diversity within this taxon, but comprehensive genomic data are necessary to resolve its phylogenetic relationships and refine its taxonomic diversity. Although the species is currently listed as Least Concern on the IUCN Red List, its population is experiencing a decline due to impacts of human activities. The Rednose labeo is important for subsistence fisheries.
