Zebra mussels and the closely related and ecologically similar quagga mussels are filter-feeding organisms; they remove particles from the water column. Zebra mussels process up to 1 litre (0.26 US gal; 34 US fl oz) of water per day, per mussel. [9] Some particles are consumed as food, and feces are deposited on the lake floor.
Filter feeders can play an important role in condensing biomass and removing excess nutrients (such as nitrogen and phosphate) from the local waterbody, and are therefore considered water-cleaning ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. Filter feeders can be sessile, planktonic ...
Mussel (/ ˈmʌsəl /) is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean ...
a - anus. dg - digestive gland. The digestive system of gastropods has evolved to suit almost every kind of diet and feeding behavior. Gastropods (snails and slugs) as the largest taxonomic class of the mollusca are very diverse: the group includes carnivores, herbivores, scavengers, filter feeders, and even parasites.
At the larval stage, Pisaster ochraceus are filter feeders and their diet consists of plankton. As an adult, P. ochraceus feeds on mussels such as Mytilus californianus and Mytilus trossulus. They also feed on chitons, limpets, snails, barnacles, echinoids, and even decapod crustacea. [4] [9] [10] P. ochraceus uses its tube feet to handle its ...
The black mussel is a filter feeder that eats floating scraps of algae and phytoplankton. It is threatened by the invasion of the fast-growing and hardy Mediterranean mussel, which outcompetes it for space. Particulate organic matter is the major food source of many filter-feeding bivalves including C. meridionalis.
In addition, most mussels are filter feeders and filter water through their bodies to feed. This filtration makes them prime targets for picking up contaminants in the water. [3] Mussels can provide information on if a system is recovering and if a remediation or cleanup effort is effective.
The Mediterranean mussel is a filter feeder. It is rare subtidally, which is an alternate means of distinguishing it from the black mussel in South Africa. Mussels are generally considered as a bioindicators of the whole ecosystem in which they live.
