Semelidae
The Semelidae are a family (biology), family of saltwater clams, Marine (ocean), marine bivalve molluscs in the order Cardiida. Description Members of this family have rounded or oval, elongated shells, much flattened. The two valves are connected by an internal ligament in contrast to the closely related family Tellinidae where the ligament is external. The two separate siphons are very long, sometimes several times the length of the shell. These siphons have a characteristic cruciform muscle at their base. Selected genera Genera of Semelidae (with some notable species also listed) include: *''Abra (bivalve), Abra'' Lamarck, 1818 **''Abra aequalis'' (Thomas Say, Say, 1822) **''Abra alba'' (Wood W., 1802) **''Abra californica'' Kundsen, 1970 **''Abra lioica'' (W.

Scrobicularia Plana
''Scrobicularia plana'', the peppery furrow shell, is a bivalve mollusc belonging to the family Semelidae. Taxonomy Although ''Scrobicularia plana'' is the only species currently recognized by ITIS in the genus ''Scrobicularia''; World Register of Marine Species recognises another species, ''Scrobicularia cottardi'' as well as some Nomen dubium, nomen dubia, as does the BioLib. The genus ''Scrobicularia'' is sometimes placed as the sole genus in a family, Scrobicularidae. It is now often placed instead in the related family Semelidae, as shown in the infobox. However this placement may change as molecular systematics provides new insights into the cladistics of the bivalves. Description The shell can be anything from white through yellowish to a pale brownish-grey in colour, up to 6.5 cm in diameter. Its interior is nacreous and white or yellowish in colour. The shell is thin but quite deep, with circular closely packed growth ridges. It is a filter feeder, with long sipho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Abra Prismatica
''Abra prismatica'' is a species of bivalve mollusc in the family Semelidae. It occurs in the northeastern Atlantic Ocean, the North Sea and the Mediterranean Sea, where it lives on the seabed, in shallow areas buried in soft sediment. Description ''Abra prismatica'' grows to a length of about . Each shell valve is fine and brittle, about twice as long as it is wide and oval or fusiform. It is sculptured with fine concentric lines, the chondrophore (pit to which the internal ligament is attached) points to the posterior. On the right valve are two small cardinal teeth in front of the chondrophore, and a single anterior and single posterior lateral teeth behind it. On the left valve there is a single small cardinal tooth and two small anterior and posterior laterals. The valves are shiny white both inside and out. Distribution ''Abra prismatica'' is found on the coasts of northwest Europe, the North Sea and the Mediterranean Sea at depths down to about . It is common around the Br ...

Abra (bivalve)
Abra is a genus of saltwater clams, marine bivalve mollusks in the family Semelidae. Members of this genus are mostly under 1.5 centimeters long, and have thin shells which are usually white. These bivalves normally live under the surface of sandy and muddy sediments, in the neritic zone The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminate .... They are considered an important food source for flat fish.Rees, H.L. and Dare. P.J (1993)Sources of mortality and associated life-cycle traits of selected benthic species: a review. Fisheries Research Data Report No. 33, Directorate of Fisheries Research, Lowestoft.

Abra Alba
''Abra alba'', or the white furrow shell, is a species of bivalve mollusc in the family Semelidae. It occurs in the northeastern Atlantic Ocean and the Mediterranean Sea, where it lives on the floor in shallow areas buried in soft sediments. Description ''Abra alba'' can grow to up to long but a more usual size is 1.5 centimetres. It has a pair of thin brittle valves that are translucent, semi-shiny and a dirty white colour with a pale brown periostracum. The shape is roughly oval and the posterior and anterior dorsal margins are almost straight and slope to rounded ends. Both margins are smooth and the anterior margin is a little longer than the posterior one. The valves have a sculpture of fine concentric lines and the growth stages of the animal are visible. The interior of the valves is somewhat glossy and the adductor muscle scars may be visible. The small brown ligament that holds the valves together is exterior.
