Sea urchins – ECHINOIDEA

Underside of a purple sea urchin, teeth open

Records held by the Atlas of Living Australia show that at least 32 species of sea urchins have been sighted in South Australian waters. In order to minimise the threat of erroneous records falsely extending this list, I’ve only included species for which at least two sighting records were found.
