There are at least 37 species of brittle stars and basket stars in South Australian waters.
The list below was prepared after reviewing records held by the Atlas of Living Australia. Only species for which at least two records exist were included, and records lacking location details were also dropped from the list to avoid any potentially erroneous inclusions.
Pictures of any of the below species taken in SA waters are invited, along with any suggestions re: improving the accuracy or completeness of the list.
