Phylum Echinodermata

Class Ophiuroidea, Brittle Stars

Brittle stars are highly mobile echinoderms with flexible jointed arms and distinct central disc.  As their name implies, arms break off readily when disturbed, growing back with time.  They feed as scavengers or capture organic material suspended in the water column.
