Abstract
A study of the food uptake and feeding behaviour of 150 specimens of Porania pulvillus was performed in situ by SCUBA diving in waters off the Swedish Skagerrak coast. The results of this study and observations in aquaria show that this sea-star is not solely a ciliary feeder as hitherto believed. Among its prey are the octocoral Alcyonium digitatum, the brachiopod Crania anomala, and several species of ascidians.Keywords
