Being members of the Phylum Mollusca, mussels are closely related to other bivalves, marine mussels and clams, as well as snails and even octopuses. Freshwater mussels may also be threatened by changes in fish species composition, dams that limit passage of diadromous fish species, and the potential spread of invasive non-native species like zebra mussels. A mussel is a type of bivalve mollusk that can be found in fresh water lakes, streams, and creeks, along with the salty inter-tidal zone where oceans meet the shore.

The distribution of the component taxa has been recently modified as a result of human activity. Human Use of Mussels. Other bivalves have used the…. Blue mussels were also harvested by the indigenous peoples of North America. Larval development can last from 15 to 35 days depending environmental conditions including salinity and temperature, as well as location. The genetically distinct lineage of M. edulis present in the Southern Hemisphere has been attributed to subspecies Mytilus edulis platensis (now Mytilus platensis).[3]. The veliger continues to mature forming the prodissoconch II shell. In their natural environment many creatures prey on bivavles. Small mussels are also eaten by the dog whelk, Nucella lapillus. Characterized by a functional mouth and alimentary canal the veliger stage also has cilia which are used for filtering food as well as propulsion. Beds generally form from fields that persist long enough to establish a dense population. Mussels are eaten steamed, sauteed, baked or grilled. [14] The blue mussel is host to a wide range of parasites, but these parasites usually do not cause much damage. Mussels are topped with a rich curry butter, sealed in foil packets, and grilled until done in this terrific recipe. Bivalves tend not to be very mobile, settling in the one place as adults. The reproductive strategy seen in blue mussels is characteristic of planktotrophs. They vary in their adult sizes from those as small as a thumbnail to others … They multiply rapidly and are … Some attach themselves to hard … Such a shell form and habit evolved first within sediments (endobyssate), where the byssus serves for anchorage and protection when formed into an enclosing nest. Mussels are members of the second largest group of animals in the world, the Mollusks. However much of what we eat is farmed. The majority are eaten by predators before completing metamorphosis. Journal of the Marine Biological … But in general, a fresh mussel is closed or closes when you tap on it; discard any open mussels. Larvae originating from Connecticut mature normally at 15–20 Â°C (59–68 Â°F), though at 15 Â°C (59 Â°F) normal development occurs at salinities between 15 and 35 ppt and 20 at 35 ppt at 20 Â°C (68 Â°F). The capability of shell thickening by mussels has become a very effective defense mechanism. Bivalve molluscs are found in aquatic environments, with the majority (about 80%) being marine species. The larvae of some mussel species are temporarily parasitic. The mussel will remain in that state until reaching 1-1.5mm in length. Although there are about 10,000 sperm per egg,[5] large proportions of eggs deposited by blue mussels are never fertilized.

By minimizing nutrients in egg production to the bare minimum they are able to maximize the number of gametes produced. edulis. They may be smooth or ribbed and often have a hairy covering. Freshwater mussels, also called naiads or unionids by scientists, consist of a soft … Unlike B.C.’s native mussels, Zebra and Quagga mussels attach to hard surfaces, allowing them to be moved between water bodies by boats and equipment. [4] In Europe it is found from French Atlantic coast northwards to Novaya Zemlya and Iceland, but not in the Baltic Sea. In general, bivalves are filter feeders, passing water through their gills to extract organic food particles known as plankton. Byssal thread are secreted by byssal glands located in the foot of the mussel, and are made up of polyphenolic proteins are proteins which serve as a bioadhesive. Mussels are also an important food source for several different kinds of terrestrial and aquatic animals, including muskrats and raccoons, as well several species of fish. Note: Examine mussels … Mussels can be eaten by a variety of birds like gulls but more likely to be consumed by other creatures such as squids, octupus, or sea otters. Marine mussels are usually wedge-shaped or pear-shaped and range in size from about 5 to 15 centimetres (about 2 to 6 inches). When possible, mussels will thus migrate to lower densities on larger scales (>7.5 cm), but aggregate on small scales (<2.0 cm). Marine mussels reproduce by releasing their eggs and sperm into the water. Like oysters and clams, they are served in their shells atop salads or pasta dishes or garnished on the half-shell as an appetizer. Mussels are filter feeders that filter microscopic aquatic life, such as plankton, from the water around them. At this point although mobile, it is still reliant on the yolk for nutrients. They may be smooth or ribbed and often have a hairy covering. These are collagenous protein strands used for attachment. [citation needed] Once the sperm and eggs are fully developed they are released into the water column for fertilization. During this stage it is susceptible to jellyfish and fish larvae through adults. Wouldn't have believed it if we hadn't actually seen it. … Collectively they occupy both coasts of the North Atlantic (including the Mediterranean) and of the North Pacific in temperate to polar waters,[2] as well as coasts of similar nature in the Southern Hemisphere. Even dead mussels can be a nuisance, littering beaches with shells. When faced with two species at a time, they are no longer able to use their defenses and can be killed more easily. Blue mussels are boreo-temperate invertebrates that live in intertidal areas attached to rocks and other hard substrates by strong (and somewhat elastic) thread-like structures called byssal threads, secreted by byssal glands located in the foot of the mussel. "Genetics and taxonomy of Chilean smooth-shelled mussels, "Experimental Evidence for Spatial Self-Organization and Its Emergent Effects in Mussel Bed Ecosystems", "Beds of blue mussels and Pacific oysters", "Blue Mussels in Decline in Gulf of Maine", "Why are New England's wild blue mussels disappearing?". If boats are left moored in zebra mussel infested waters run the engine at least twice a week at slow speeds (about 4-½ mph) for 10 to 15 minutes. Seals are … Ochre seastars (Pisaster ochraceus) feed on invertebrates, such as coral and shellfish, like the mussels pictured here. Freshwater mussels were used by early Americans. "Mussels" actually refers to the common name for a number of different species. Mussels filter out bacteria, metals, and toxins, that would increase significantly without mussels around. Blue mussels are subject to commercial use and intensive aquaculture. Newly settled mussels are particularly difficult to detect as they are only a few mm's in size. What animals eat mussels? Mussels attach … Mussel beds are persistent, dense mussel populations. Mussels Mytilus edulis: significant consumers and destroyers of mesozooplankton. The taxa can hybridise with each other, if present at the same locality. [18], Numerous empty blue mussel shells on a beach in Iceland, Blue mussel sculpture at Conwy, North Wales near Conwy Castle, "Genetic diversity and connectivity within Mytilus spp. [9] When densities are low, for example in mussel fields – short-lived mussel populations – clumped distribution patterns are seen. They are capable to scavenge for foods at great depths. actually I use to have a mussel in my fish tank, and the fish ate it. [9] In areas where blue mussels are threatened, such as the Wadden Sea, it is of great importance to enhance the survival of mussel fields, of which mussel aggregates are the primary component.
