Estimated genome size:
1.5 m in height
Size:
1.5 m in height
Distribution:
Brunia noduliflora occurs from the Cederberg southwards to the Cape Peninsula and eastwards as far as the Cockscomb in the Groot Winterhoek Mountains of the Eastern Cape, at altitudes from near sea level to approximately 1 500 m.
PromethION Sequencing Report:
Output:
39.88 Gigabases
Approximate N50:
16.91 kilobases

Tropidophora ligata
Smooth shuffler

Importance:
South Africa's indigenous terrestrial snails are valuable bioindicators due to their restricted ranges and microhabitat specialization. Habitat loss threatens many species, highlighting the need to understand their diversity and ecology. The genus Tropidophora is especially interesting, as its closest relatives are intertidal periwinkles (Littorinidae), yet little is known about its terrestrial adaptations.
