Project summary: 
About 8,000 species of echinoderms have been described worldwide and, according to the Barcode of Life Data Systems (BOLD,, approximately a forth of them have been barcoded. However, less than 300 of the ca. 29,000 echinoderm barcode records available on BOLD are from South Africa, a country with a coastline of more than 2,500 km on both the Atlantic and Indian Oceans. This project will in the first place deliver COI DNA sequences obtained from specimens and taxa collected in locations were no such records are known. Sequences of these >350 specimens will be publicly available on GenBank and BOLD and will allow cross-identifications of specimens of sea urchins, sea cucumbers, ophiuroids and starfish identified through traditional taxonomy. In particular, they will help identifying crinoids sampled during five expeditions in South Africa. For the sea cucumbers of the family Holothuriidae, barcodes will be used in an integrative systematical revision currently developed at the University of Florida. Finally, updated checklists of the shallow water echinoderms of KwaZulu-Natal will be elaborated using the DNA data produced here.

Output: COI sequences of a total of 351 specimens collected during five different campaigns (from 1999 to 2016) in the North and South of the KwaZulu-Natal Province, across two distinct offshore environments have been obtained. Morphological and molecular identifications allowed distinguishing ca. 114 species, including a number of new records for the country and some putative new species. These included Crinoidea (96 specimens and ca. 10 species), Ophiuroidea (95 specimens and ca. 44 species), Asteroidea (48 specimens and ca. 19 species), Echinoidea (27 specimens and ca. 12 species) and Holothuroidea (85 specimens and ca. 29 species). Data still private in BOLD.
