5203 |a"Six invertebrate prey were offered to the sunflower starfish, Pycnopodia helianthoides, in order to measure their selective feeding rate on green sea urchins (Strongylocentrotus droebachiensis). Highly selective feeding was observed, in this order from most to least selected: manila clams (Venerupis japonica), butter clams (Saxidomus giganteus), native littleneck clams (Protothaca staminea), green sea urchins, red sea urchins (S. franciscanus) and Pacific oysters (Crassostrea gigas). These results do not support the idea that Pycnopodia are an important limiting predator on green sea urchins. They may limit the lower distribution of Manila clams in the intertidal zone. Feeding rates calculated from this study were estimated to be 28 kg wet wt/adult/year"--Abstract, page iii.
