FEEDING RATES OF THE MUD SHRIMP UPOGEBIA PUGETTENSIS AND IMPLICATIONS FOR ESTUARINE PHYTOPLANKTON ABUNDANCE
The burrowing shrimp Upogebia pugettensis is an abundant inhabitant of Pacific Northwest bays and estuaries where it lives commensally with the clam Cryptomya californica. Suspension-feeding activities of the shrimp and its commensal clam, as well as particle settlement within the burrow, represent...
