Useful interactions with molluscs range from their use as food, where species as diverse as snails and squid are eaten in many countries, to the employment of molluscs as shell money and to make dyestuffs and musical instruments, for personal adornment with seashells, pearls, or mother-of-pearl, as items to be collected, as fictionalised sea ...
This is a partial list of edible molluscs. Molluscs are a large phylum of invertebrate animals, many of which have shells . Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and ...
The following is a list of types of seafood. Seafood is any form of sea life regarded as food by humans. It prominently includes shellfish, and roe. Shellfish include various species of molluscs, crustaceans, and echinoderms. In most parts of the world, fish are generally not considered
With the help of the protein contained in the mussel and iron filtered from the sea, this gland produces the byssus threads with which the mussel can hold on. Mussels have a sphincter, which is located in the soft tissue of the mussel, as well as other organs (heart, stomach, intestines, kidneys).
Mussel (/ ˈ m ʌ s ə l /) 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.
In China and Japan, where it is native, the mussels are found in intertidal zones with densities up to 2500 individuals per square metre. In Australia, as an invasive species , they are found from 0.5 to 4 metres ( 1 + 1 ⁄ 2 to 13 feet) below the surface of the water in slightly higher densities.
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 ...
Mytilida is an order of marine bivalve molluscs, commonly known as true mussels. [1] There is one extant superfamily, the Mytiloidea , with a single extant family, the Mytilidae . Species in the order Mytilida are found worldwide, but they are more abundant in colder seas, where they often form uninterrupted beds on rocky shores in the ...
