Despite the apparent dominance of Ophiothrix fragilis, up to 78 species have been recorded from a brittle star bed (of which half the biomass was O. fragilis) the most common of which was the bivalve Abra alba (Warner, 1971). Brittle Star arms attach to a well defined central disk. Brittle stars have a very low defense stat and low health, which allows bulkier builds to easily take it down.

The Brittle Stars of the Ophiocomidae Family have all been placed in the Phylum Echinodermata (meaning spiny skin), which includes the Basket Stars, Sea Cucumbers, Sea Stars and Sea Urchins that are of great scientific interest because, via fossil records, they date to the Cambrian Age (over 500,000,000 years ago) with approximately 20,000 species of which more than half are extinct.
