Clam
Clam is a common name for several kinds of bivalve mollusc. The word is often applied only to those that are deemed edible and live as infauna, spending most of their lives halfway buried in the sand of the sea floor 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. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting ...

Clam Chowder
Clam chowder is any of several chowder soups in American cuisine containing clams. In addition to clams, common ingredients include diced potatoes, salt pork, and onions. It is believed that clams were used in chowder because of the relative ease of harvesting them. Clam chowder is usually served with saltine crackers or small, hexagonal oyster crackers. The dish originated in the Northeastern United States, but is now commonly served in restaurants throughout the country. Many regional variations exist, but the three most prevalent are New England or "white" clam chowder, which includes milk or cream; Manhattan or "red" clam chowder, which includes tomatoes; and Rhode Island or "clear" clam chowder, which omits both. History Early documentation of "clam chowder" as known today did not contain milk and was thickened during cooking using crackers or stale bread. The first recipe for Manhattan clam chowder, with tomatoes and no milk, was published before 1919, and the current ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clam Digging
Clam digging is a North American term for a common way to harvest clams (edible infaunal bivalve mollusks) from below the surface of the tidal sand flats or mud flats where they live. It is done both recreationally (for enjoyment or as a source of food) and commercially (as a source of income). Commercial digging in the U.S. and Canada is colloquially referred to as ''clamming'', and is done by a ''clammer''. Amateur clam digging is often done using a straight long-handled spading fork, or a spading shovel. Commercial clamming for quahog clams, and the larger surf clams (soup clams) is primarily done offshore, via mechanical dredging. To harvest cultivated clam beds, aquaculturists often use a much smaller version (hand pulled) from the offshore dredge. Another form of commercial clamming is done from a flat-decked boat using a clam rake with a telescopic handle. The head of these rakes have long tines attached to a "basket-like" cage in which the clams are col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bivalvia
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class (biology), class of aquatic animal, aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-bivalve shell, shells known as valve (mollusc), valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidium (mollusc), ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, Cockle (bivalve), cockles, mussels, scallops, and numerous other family (biology), families that live in saltwater, as well as a number of families that live in freshwater. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ming (clam)
Ming ( 1498 or 1499–2006), also known as Hafrún, was an ocean quahog clam (''Arctica islandica'', family Arcticidae) that was fishing dredge, dredged off the coast of Iceland in 2006 and whose age was calculated by counting annual growth lines in the shell. Ming was the oldest individual (non-Clonal colony, clonal) animal ever discovered whose age could be precisely determined. Thought to be 405 years old, Ming was later determined to be 507 years old, although the clam had previously been killed to make this determination. The size of the clam was . Name The clam was initially named Ming by ''Sunday Times'' journalists, in reference to the Ming dynasty in China, during which it was born. Later, the Icelandic researchers on the cruise which discovered the clam named it Hafrún, a woman's name which translates roughly as 'the mystery of the ocean'; taken from , 'ocean', and , 'mystery'. The actual sex of the clam, however, is unknown, as its reproductive state was recorded as " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siphon (mollusc)
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three Class (biology), classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives). Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as animal locomotion, locomotion, feeding, respiration (physiology), respiration, and reproduction. The siphon is part of the mantle (mollusc), mantle of the mollusc, and the water flow is directed to (or from) the Mantle (mollusc)#The mantle cavity, mantle cavity. A single siphon occurs in some gastropods. In those bivalves which have siphons, the siphons are paired. In cephalopods, there is a single siphon or funnel which is known as a hyponome. In gastropods In some (but not all) sea snails, Marine (ocean), marine gastropod molluscs, the animal has an anterior extension of the man ...

Mollusca
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valve (mollusc)
A valve is each articulating part of the shell of a Mollusca, mollusc or another multi-shelled animal such as Brachiopod, brachiopods and some Crustacean, crustaceans. Each part is known as a valve or in the case of Chiton, chitons, a "plate". Members of two Class (biology), classes of molluscs, the Bivalvia (clams) and the Polyplacophora (chitons), have valves. Species within one family of very unusual small sea snails, marine (ocean), marine opisthobranch gastropods in the family Juliidae, also have two articulating shells or valves, which resemble those of a bivalve. This exceptional family is commonly known as the bivalved gastropods. Gastropods in general are sometimes called "univalves", because in those that have a shell, the shell is usually in one part. Chitons The valves of chitons are eight dorsum (biology), dorsal, wiktionary:articulated, articulated shell plates, which are frequently coloured and sculpted. After death the girdle that holds the plates together disin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and Freshwater bivalve, 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. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong Byssus, byssal threads ("beard") to a firm substrate. A few species (in the genus ''Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Sea Lion
The California sea lion (''Zalophus californianus'') is a coastal eared seal native to western North America. It is one of six species of sea lions. Its natural habitat ranges from southeast Alaska to central Mexico, including the Gulf of California. California sea lions are Sexual dimorphism, sexually dimorphic; males are larger than females, and have a thicker neck, and a protruding sagittal crest. They mainly Hauling-out, haul out on sandy or rocky beaches, but they also frequent manmade environments such as marinas and Wharf, wharves. California sea lions feed on a number of species of fish and squid, and are preyed on by orcas and great white sharks. California sea lions have a Polygyny in animals, polygynous breeding pattern. From May to August, males establish territory (animal), territories and try to attract females with which to mate. Females are free to move in between territories, and are not coerced by males. Mothers nurse their pups in between foraging trips. Califo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
