Congratulations to Emily Garlich of Kamilche Sea Farms.
Her picture shows blue mussels growing on longlines of her mussel farm feeding. White sea anemones are growing with them. The mussels are sucking in sea water filtering out phytoplankton helping to keep phytoplankton blooms in check. You can see their mantles,
the tissue just inside the shell, making a siphon to channel the water over the gills toward the mouth for feeding. Contest link
