The California mussel (Mytilus californianus) is a large edible mussel, a marine bivalve mollusk in the family Mytilidae. This species is native to the west coast of North America , occurring from northern Mexico to the Aleutian Islands of Alaska .
Anodonta californiensis, the California floater, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. Description [ edit ]
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).
Those who observe any suspected golden mussels in California are asked to file a report through CDFW's Invasive Species Program, either by filling out the form online, emailing invasives@wildlife ...
Osmoregulation, or the maintenance of constant salinity within body tissue and fluids, is another challenge faced by freshwater Mollusca. Dillon (2000) [2] indicates that they have characteristically low tissue salinities relative to other freshwater animals, and unionid mussels have some of the lowest tissue salinities of any animal.
Freshwater mussels are used as host animals for the cultivation of freshwater pearls. Some species of marine mussel, including the blue mussel (Mytilus edulis) and the New Zealand green-lipped mussel (Perna canaliculus), are also cultivated as a source of food. Bouchots are marine pilings for growing mussels, here shown at an agricultural fair.
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 ...
