Description
Definition Assemblages dominated by crawling, epifaunal, crevice-dwelling brittle stars, often living on, between, or under rocks. Brittle stars (together with basket stars) are Ophiuroids, a relatively mobile class of echinoderms. Some brittle star species are specialized for life on or among rocks and other hard substrates, others are specialized for infaunal burrowing, and some species may be generalists, found in a variety of substrates, and utilizing a variety of feeding methods.
