Euryale aspera


This site contains authoritative information about the echinoderm class Ophiuroidea (brittle stars and basket stars) for the general public and fellow researchers. The focus of this site lies primarily with taxonomy and phylogeny, but general biology and ecology are included when appropriate. At present, taxon names are automatically linked to various types of information on external sites all over the internet. Please, feel free to explore. For an up-to-date authoritative taxonomy please visit the World Ophiuroidea database at


You can use the taxonomy search field and enter a taxon name. The taxonomy includes current species names as well as higher taxa. To navigate the classification click on a term in the classification menu and a child taxon will open as well as a view with multiple panels for this taxon.

To search for non-taxonomy items use the search field at the top of each page.
