Phylum:

Chordata

Estimated genome size:

65 cm TL

Organism size:

Distribution:

Endemic to South Africa from the mouth of the Orange river through to KwaZulu-Natal. Adults inhabit inshore marine environments to 25 m depth, usually over sandy or mixed sand and rock shorelines. Juveniles have an obligatory estuarine dependent nursery phase.

Oxalis natans

Species Card Details

Draft Genome Assembly Statistics:

Genome Length:

432.36 Mb

BUSCO completeness score (single and duplicated genes):

99.6%

Importance:

This highly threatened species is one of the true aquatic species in Oxalis, but much of its original habitat has been lost to urbanisation. Interestingly, it is completely unrelated to the other aquatic species - the genome of this species may offer insights into its conservation, and also into the convergent evolution of an aquatic habit in South African Oxalis. It is Redlisted as Critically Rare.
