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.
