About Mussel

Elongated bivalve molluscs, typically filter feeders attached to rocks or other surfaces. Modiolus modiolus, common name northern horsemussel (Scottish Gaelic: clabaidh-dubh, Scots: clabbydoo), is a species of marine bivalve mollusk in the family Mytilidae. Nomenclature In Scottish Gaelic, the species is called 'clabaidh-dubha' ('clabby doos'), meaning 'big black mouths'. More recently in Scotland the species is commonly known and referred to as 'clappy-doo'. In the Shetland dialect, they are known as "yoags". Description Modiolus modiolus is a large mussel growing to 22 cm (9ins) long though 10 cm (4ins) is a more typical size. The shell is purplish or dark blue and robust, with horny protuberances when young. The two valves are roughly triangular or bluntly oblong with rounded umbones near the anterior end. The annual growth lines are clear and there is a fine sculpturing of concentric grooves and ridges. The interior of the shell is white with a broad pallial line, large anterior adductor muscle scar and smaller posterior adductor muscle scar. The body is deep orange and the mantle is unfrilled. The shell is firmly attached to the substrate by byssus threads. Distribution M. modiolus can be found along the Atlantic coast of North America, from the Arctic... The Mytilidae are a family of small to large marine and brackish-water bivalve molluscs in the order Mytilida. One of the genera, Limnoperna, inhabits freshwater environments. Mytilidae, which contains some 52 genera, is the only extant family within the order Mytilida. Species in the family Mytilidae are found worldwide, but they are more abundant in colder seas, where they often form uninterrupted beds on rocky shores in the intertidal zone and the shallow subtidal. The subfamily Bathymodiolinae is found in deep-sea habitats. Mytilids include the well-known, edible sea mussels. 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 the Mytilidae recovered two main clades derived from an epifaunal ancestor, with subsequent lineages shifting to other lifestyles, and correlating convergent evolution of siphon traits. Subfamilies and genera As of March 2025, the World Register of Marine Species accepts 32 genera split into eight subfamilies. Subfamily Brachidontinae Brachidontes Swainson, 1840 Geukensia Van de Poel, 1959...
