Limopsidae is a family of bivalves, related to the ark clams and bittersweets. This family contains about thirty species in seven genera.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Ark clam family of molluscs

Ark clam is the common name for a family of small to large-sized saltwater clams or marine bivalve molluscs in the family Arcidae. Ark clams vary both in shape and size. They number about 200 species worldwide.

Glycymerididae family of molluscs

Glycymerididae, previously known as Glycymeridae, common names dog cockles or bittersweets, is a worldwide family of salt water clams, marine bivalve mollusks in the order Arcida. They are related to the ark clams. This family contains 45 species in four genera.

Limopsis sulcata, common name the sulcate limopsis, is a species of very small clam, a marine bivalve mollusk in the family Limopsidae. This species occurs along the Atlantic coast of North America from Massachusetts to the West Indies.

Limopsis

Species of the genus Limopsis are among the few suspension feeding deep-sea bivalves, and are absent from the continental shelf. They are relatively small, byssate (i.e. attached to the sea floor by strong threads, or byssus), and, while the viscera are reduced, there is a comparatively thick shell. Differences between species are usually defined by minor differences in gill and palp structure. The eggs are relatively few and of a size which suggests that the planktonic larvae do not feed.

Continental shelf A portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea

A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea. Much of the shelves were exposed during glacial periods and interglacial periods.

Byssus fine, rare fiber secreted by mollusks of the Pinnidae family

A byssus is a bundle of filaments secreted by many species of bivalve mollusk that function to attach the mollusk to a solid surface. Species from several families of clams have a byssus, including the pen shells, the true mussels and the false mussels: the Pinnidae, the Mytilidae and the Dreissenidae.

Gill respiratory organ

A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia is the zoologists' name for gills.
