Scale liars are (1,2 cm. studies on other suspension feeders have investigated the effects of individual or zooid or polyp spacing on feeding success. For example, phoronids are not colonial, hut these lophophorate suspension feeders can live in very dense aggregations (up to 20,000 m~2) (Johnson, 1997). On the basis of studies of growth and of flow around neighboring phoronids, Johnson (1990, 1997) predicted increased feed- ing success when there is an upstream neighbor; however, this advantage disappeared when the upstream neighbor was within one lophophore's diameter (~1 cm)..
