| Abstract |
The feeding behavior of three species of spionid polychaetes (Pseudopolydora kempi japonica, Boccardia proboscidea, and Pygospio elegans) varied with water velocity. At moderate flows the worms ceased deposit feeding, formed their feeding tentacles into helices, and lifted them into the water column to capture material in suspension. This behavior was apparently a response to increased flux of suspended matter at high flows rather than to flow velocity alone. Organisms capable of switching their feeding behavior may be common in dynamically variable benthic environments. |
