Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America.
The bearded seal, also called the square flipper seal, is a medium-sized pinniped that is found in and near to the Arctic Ocean. It gets its generic name from two Greek words that refer to its heavy jaw. The other part of its Linnaean name means bearded and refers to its most characteristic feature, the conspicuous and very abundant whiskers. When dry, these whiskers curl very elegantly, giving the bearded seal a "raffish" look.
The blue mussel, also known as the common mussel, is a medium-sized edible marine bivalve mollusc in the family Mytilidae, the mussels. Blue mussels are subject to commercial use and intensive aquaculture. A species with a large range, empty shells are commonly found on beaches around the world.
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. These pools typically range from a few inches to a few feet deep and a few feet across. Many of these pools exist as separate bodies of water only at low tide, as seawater gets trapped when the tide recedes. Tides are caused by the gravitational pull of the sun and moon. A tidal cycle is usually about 25 hours and consists of one or two high tides and two low tides.
Mytilidae are a family of small to large marine and brackish-water bivalve molluscs in the order Mytilida. One of the genera, Limnoperna, even inhabits freshwater environments. The order has only this one family which contains some 52 genera.
Perna perna, the brown mussel, is an economically important mussel, a bivalve mollusc belonging to the family Mytilidae. It is harvested as a food source but is also known to harbor toxins and cause damage to marine structures. It is native to the waters of Africa, Europe, and South America and was introduced in the waters of North America.
Modiolus, the horsemussels, are a genus of medium-sized marine bivalve molluscs in the family Mytilidae.
The Skerries are a small group of rocky islands (skerries) just off Portrush, County Antrim, on the north coast of Northern Ireland. Winkle Isle is the local name for the large Skerry island, the small Skerry being known as Castle Isle. The islands are part of an Area of Special Scientific Interest.
Modiolus modiolus, common name northern horsemussel, is a species of marine bivalve mollusk in the family Mytilidae.
Brachidontes is a genus of mussels in the family Mytilidae.
Arca noae or the Noah's Ark shell is a species of bivalve mollusc in the family Arcidae. It is found in the Mediterranean Sea from low tide mark to a depth of 60 metres (200 ft).
Modiolus albicostus is a species of "horse mussel", a marine bivalve mollusc in the family Mytilidae, the mussels.
Stomphia coccinea is a small reddish, orange or brownish sea anemone in the family Actinostolidae from the North Atlantic, North Pacific and Arctic Ocean. It can swim away when necessary in order to escape a predator.
Modiolus capax, common name fat horsemussel, is a species of "horse mussel", a marine bivalve mollusc in the family Mytilidae, the mussels. It was first described to science by American malacologist Timothy Abbott Conrad in 1837. The type specimen was collected in San Diego by Thomas Nuttall.
Modiolus philippinarum, common name Philippine horse mussel, is a species of "horse mussel", a marine bivalve mollusc in the family Mytilidae, the mussels.
Arcuatula perfragilis is a bivalve mollusc of the mussel family, Mytilidae, which has an Indo-Pacific distribution including the Red Sea. It has invaded the eastern Mediterranean from the Red Sea by way of the Suez Canal, a process known as Lessepsian migration.
Modiolus auriculatus, the eared horse mussel, is a bivalve mollusc of the family, Mytilidae, which has a natural range in the Indian and Pacific Oceans. It has colonised the eastern Mediterranean Sea from the Red Sea by Lessepsian migration via the Suez Canal.
Modiolus areolatus, or the bearded horse-mussel a species of bivalve mollusc in the family Mytilidae. It is found in New Zealand. Its shell typically is 90 millimetres (3.5 in).
