The blue mussel (Mytilus edulis), also known as the common mussel, [1] is a medium-sized edible marine bivalve mollusc in the family Mytilidae, the only extant family in the order Mytilida, known as "true mussels". Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, empty shells are commonly found ...
Mytilus trossulus, the Pacific blue mussel, bay mussel or foolish mussel, is a medium-sized edible marine bivalve mollusc in the family Mytilidae.. Mytilus trossulus is one of the three principal, closely related taxa in the Mytilus edulis complex of blue mussels, which collectively are widely distributed on the temperate to subarctic coasts the Northern Hemisphere, and often are dominant ...
Blue mussels, Mytilus edulis, are sessile and exhibit clumping. Clumping is a behavior in sessile organisms in which individuals of a particular species group closely to one another for beneficial purposes, as can be seen in coral reefs and cochineal populations. This allows for faster reproduction and better protection from predators. [3]
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and ...
In marine mussels, fertilization occurs outside the body, with a larval stage that drifts for three weeks to six months, before settling on a hard surface as a young mussel. There, it is capable of moving slowly by means of attaching and detaching byssal threads to attain a better life position. Freshwater mussels reproduce sexually.
The taxonomic term Bivalvia was first used by Linnaeus in the 10th edition of his Systema Naturae in 1758 to refer to animals having shells composed of two valves. [3] More recently, the class was known as Pelecypoda, meaning "axe-foot" (based on the shape of the foot of the animal when extended).
A common feature of the shells of mussels is an asymmetrical shell which has a thick, adherent periostracum. The animals attach themselves to a solid substrate using a byssus . A 2020 study of the phylogeny of Mytilidae recovered two main clades derived from an epifaunal ancestor, with subsequent lineages shifting to other lifestyles, and ...
Mytilus chilensis is part of the worldwide Mytilus edulis complex of mussels, or blue mussels. Modern genetic studies based on single-nucleotide polymorphism (SNP) have demonstrated that the Chilean mussel is genetically different of both the Mediterranean mussel ( Mytilus galloprovincialis ) and the North Atlantic Mytilus edulis .
