These strange and beautiful creatures do … Several recent studies also showed that phytoplankton is not necessary primary food source for bivalves and pointed out the importance of other food sources such as bacteria, detritus and even zooplankton, including bivalve larvae. Recent overseas studies have shown that under experimental and field conditions, blue mussels (Mytilus edulis) will … Zooplankton may be herbivores or plant-eaters (eat phytoplankton), carnivores or meat eaters (eat other zooplankton) or omnivores, which eat both plants and animals (eat phytoplankton and zooplankton). Some giant clams really are gigantic; THE giant clam, T. gigas, can weigh in at well over 400 pounds and live for a century. So what do bivalves eat? Rockfish, the smallest species of fish we offer, live on small fish and krill, while the slightly larger … Zooplankton consume a variety of bacterioplankton, phytoplankton, and even other zooplankton species. Since such organisms reside at the surface of bodies of water, zooplankton are also typically found in the upper waters. While some types of bivalves are carnivorous, the types that are commonly consumed use their gills to draw in phytoplankton and algae while filtering out larger particles. Until recently, the potential effect of bivalve filtering on zooplankton populations has not been studied extensively. Bivalves are equipped with a unique filter feeding system, that allows them to separate food particles from water. Primary producers — including bacteria, phytoplankton, and algae — form the lowest trophic level, the base of the aquatic food web.Primary producers synthesize their own energy without needing to eat. Zooplankton Animal plankton are called zooplankton. Bivalvia (/ b aɪ ˈ v æ l v i ə /), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. The group claims the most massive living marine bivalve mollusk species. For instance, the hugest baleen whales have mouths that are specially designed to scoop up zooplankton and strain the water out of them. Although there are different species of bivalves, most of them are filter feeders, and primarily live on phytoplankton and algae, organisms freely floating through the water. They are, in fact, among the largest of all invertebrate animals. Producers. The fact that they continue to eat plenty of zooplankton throughout adulthood accounts for their rich, characteristically red hue. The world’s largest animal, the great blue whale, is a zooplankton eater. But without jellyfish and many fish, which eat zooplankton, the Bay's grazers might eat all the algae in the estuary — not a good plan for the long-term health of the ecosystem. Bivalve - Bivalve - Food and feeding: The primitive bivalve was almost certainly a detritivore (consumer of loose organic materials), and the modern palaeotaxodonts still pursue this mode of life. Zooplankton are important for keeping algae from growing out of control in the Bay. Zooplankton can move on their own, but their movement is overpowered by currents. What do Zooplankton Eat?

The posterior leaflike gills serve principally for respiration; feeding is carried out by the palp proboscides, which collect surface detritus. Zooplankton Examples Krill.
