Anomia ephippium is a species of bivalve belonging to the family Anomiidae. [1]
A. ephippium is found primarily in sheltered conditions in the low intertidal and sublittoral zones. [1] They are a benthic species that lives in depths from 25-200m.
They are distributed along coasts around the world. They are found on the South and West coasts of Britain, stretching North to Shetland and are also found on all coasts of Ireland. They are also found along the Atlantic Coasts of the United States ranging from Massachusetts to Florida. [1] Specifically within the Massachusetts region, they have commonly been found in the Woods Hole region. [2]
A. ephippium is commonly known as a jingle shell or saddle oyster. [3] A. ephippium are described to have concave, semi-transparent shells of orange, yellow, and salmon-like colors. [4] The sizes range from sizes from an inch to more across. Within the bivalve itself, a thin flat shell may be found within, located under the valve of the specimen. When living, they are commonly found attached to other shells or stones, and can also be found attached to oysters. The mechanism by which they are able to attach themselves to these surfaces is by a muscle which passes through a large hole, located in the under-valve region of the specimen. [4]
A. ephippium has a 2–3 cm large thin, brittle, translucent shell structured by foliated calcite. While calcitic shells are typically white, the concentrations of polyenes A. ephippium's shells give them hues ranging from white to yellow to gray to orange.
They are a filter-feeding epifaunal species that attach to hard substrates by the byssus. [5] Anomia ephippium, along with its members of the family Anomiidae Rafinesque, attach by means of this byssus which passes through the inside of the upper left valve through a notch in its lower right valve. [6]
While information on A. ephippium's specific reproductive strategies is unavailable because they don't have a pennis , jingle shells reproduce through spawning. During the summer, gametes are released into the water column. Fertilization takes place in the mantle cavity. [7]
Bivalvia are often gonochoric, meaning they have two distinct sexes, but some are protandric hermaphrodites meaning they can change genders throughout their growth. [5] The life stage of Anomia ephippium begins at the embryonic stage post fertilization. The embryos then develop into trochophore larvae, which are described to be free-swimming. After the larval stage, Anomia ephippium develop into a bivalve veliger, which is of resemblance of a miniature clam. [5]
Bivalvia, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. The class includes the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. Shipworms bore into wood, clay, or stone and live inside these substances.
Teredo navalis, commonly called the naval shipworm or turu, is a species of saltwater clam, a marine bivalve mollusc in the family Teredinidae. This species is the type species of the genus Teredo. Like other species in this family, this bivalve is called a shipworm because it resembles a worm in general appearance while at the anterior end it has a small shell with two valves, and it is adept at boring through wood.
The Pinnidae are a taxonomic family of large saltwater clams sometimes known as pen shells. They are marine bivalve molluscs in the order Pteriida.
Perna viridis, known as the Asian green mussel, is an economically important mussel, a bivalve belonging to the family Mytilidae. It is harvested for food but is also known to harbor toxins and cause damage to submerged structures such as drainage pipes. It is native in the Asia-Pacific region but has been introduced in the Caribbean, and in the waters around Japan, North America, and South America.
Limecola balthica, commonly called the Baltic macoma, Baltic clam or Baltic tellin, is a small saltwater clam, a marine bivalve mollusk in the family Tellinidae.
Anomiidae is a family of saltwater clams, marine bivalve molluscs related to scallops and oysters, and known as anomiids. It contains seven genera.
Placunidae, also known as windowpane oysters, windowpane shells, and Capiz shells, are a taxonomic family of saltwater clams, marine bivalve mollusks which are related to oysters and scallops.
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.
Ostrea lurida, common name the Olympia oyster, after Olympia, Washington in the Puget Sound area, is a species of small, edible oyster, a marine bivalve mollusk in the family Ostreidae. This species occurs on the northern Pacific coast of North America. Over the years the role of this edible species of oyster has been partly displaced by the cultivation of non-native edible oyster species.
Isognomon is a genus of marine bivalve mollusks which is related to the pearl oysters.
Pecten maximus, common names the great scallop, king scallop, St James shell or escallop, is a northeast Atlantic species of scallop, an edible saltwater clam, a marine bivalve mollusc in the family Pectinidae. This is the type species of the genus. This species may be conspecific with Pecten jacobaeus, the pilgrim's scallop, which has a much more restricted distribution.
Anomia is a genus of saltwater clams, marine bivalve mollusks in the family Anomiidae. They are commonly known as jingle shells because when a handful of them are shaken they make a jingling sound, though some are also known as saddle oysters.
Isognomon alatus, the flat tree oyster, is a species of bivalve mollusc in the family Isognomonidae. It can be found along the Atlantic coast of North America, ranging from southern Florida to Brazil and Bermuda.
Pteria colymbus, the Atlantic winged oyster, is a species of bivalve mollusc in the family Pteriidae. It can be found along the Atlantic coast of North America, ranging from North Carolina to Bermuda and Brazil.
Anomia simplex, the common jingle shell, is a typical species of bivalve mollusc in the family of Anomiidae, sharing attributes to blue mussels, American oysters, and bay scallops. Species related to the family of Anomiidae are often noted for their extremely thin, often translucent, paper-like shells. Anomia simplex can be found in shallow waters, typically estuaries, mainly along the Atlantic Coast of North America; however, they can range as far north as the coast of Nova Scotia, and as far south as the coast of Brazil.
Pododesmus patelliformis, the ribbed saddle-oyster, is a species of bivalve mollusc in the family Anomiidae. It is found in the north east Atlantic Ocean.
Enigmonia is a genus of saltwater clams, a marine bivalve mollusc in the family Anomiidae, the jingle shells. Enigmonia aenigmatica, the mangrove jingle shell clam, is the only species in this monotypic genus. It is found living on mangroves in the Indo-Pacific Ocean.
Pteria penguin, commonly known as the penguin's wing oyster, is a species of marine bivalve mollusk in the family Pteriidae, the pearl oysters. It is native to the western and central Indo-Pacific region and is used for the production of cultured pearls. The generic name comes from Greek πτερον (pteron) meaning wing.
Pinctada margaritifera, commonly known as the black-lip pearl oyster, is a species of pearl oyster, a saltwater mollusk, a marine bivalve mollusk in the family Pteriidae. This species is common in the Indo-Pacific within tropical coral reefs.
The Anomioidea are a superfamily of marine bivalve molluscs that include two families, the Anomiidae and the Placunidae, the jingle shells and saddle shells. They are mainly sessile bivalves that superficially resemble true oysters. Though they are pleurothetic, however, the Anomioidea attach via their right valve rather than the usual left. Their irregular shells are inequilateral, are round to oval, with a large byssal notch. The byssus itself is usually short and plug-like. The left valve is convex, and the hinge is considered edentulous.
