Welcome to feather stars and friends!  This blog will explore the fascinating diversity of feather star crinoids and the many animals that live with them.  These associates include crabs, shrimps, clingfish, snails, and worms–many of which ‘mimic’ specific feather star hosts.  This system is therefore ideal for studying symbiosis, especially from an evolutionary perspective.   … Continue reading
