Euphausids: may consume phytoplankton and/ or zooplankton (primary and secondary consumer) Euphausids can be considered either primary or secondary consumers because they can eat both phyto- and zoo- plankton: (cid:862)krill(cid:863) are made up of euphausids, main food for baleen whales, commercial fishery exists for euphausids. Used in aquaculture and for pet fish. Eelgrass epiphytes (amphipod: are grazed by snails, amphipods, decapods, echinoderms, fish, isopods. This image shoes an amphipod grazing on an epiphyte an epiphyte is a type of algae that encrusts on the blades of a plant in this image the epiphyte is on the surface of a seagrass blade. Limpets graze encrusted algae leaving a trail of grazed area: not really a snail, feeds on algae on rocks.
