Map of the Southern African coastline showing some of the landmarks referred to in species range statements

The list of echinoderms of South Africa is a list of species that form a part of the echinoderm (Phylum Echinodermata) fauna of South Africa, and includes the starfish, feather stars, brittle stars, sea urchins and sea cucumbers. The list follows the SANBI listing on iNaturalist.

An echinoderm ( /ɪˈknəˌdɜːrm, ˈɛkə-/) is any deuterostomal animal of the phylum Echinodermata ( /ɪˌknˈdɜːrmətə/), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest group of deuterostomes after the chordates, as well as the largest marine-only phylum. The first definitive echinoderms appeared near the start of the Cambrian.

The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs and limbs; in some cases, they can undergo complete regeneration from a single limb. Geologically, the value of echinoderms is in their ossified dermal endoskeletons, which are major contributors to many limestone formations and can provide valuable clues as to the geological environment. They were the most used species in regenerative research in the 19th and 20th centuries. Further, some scientists hold that the radiation of echinoderms was responsible for the Mesozoic Marine Revolution. ( Full article...)
