All crinoids are suspension feeders. The fine, threadlike tube feet lining the side branches of the arms flick drifting food particles into a groove, from where cilia carry the food to the central mouth. This member of Hyocrinidae, the first record of this family from the tropical western Atlantic, is likely a species new to science.
