Ennucula aegeensis, commonly known as the Aegean nut clam, is a nut clam present in the Atlantic Ocean, Gulf of Mexico, and the Mediterranean. [1]
Ennucula aegeensis is present of the coast of Florida, North Carolina, West Indies, Gulf of Mexico, and the Mediterranean (Marmara, Aegean, and Levantine Sea). [2] E. aegeensis in the Mediterranean is typically found 80–500 m under the sea, its lower limit is around 1000 m. However, under 500–600 m it is usual replaced by E. corbuloides.E. aegeensis occupies muddy sandy-bottoms. [1] [3] E. aegeensis fossils have been found near the islet of Sokastro dating back to the early Calabrian (1.7-1.6 Ma). [4]
Ennucula aegeensis has an obliquely oval, white, shell. That has fine conmarginal striae on the exterior, the interior as radially ribbed structures that appear as fine radial striations. The interior margins are minutely denticulate. They are typically 3 mm in length. They are endobenthic (living within seafloor sediment) and are deposit feeders who consume refractory material.

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. The shipworms bore into wood, clay, or stone and live inside these substances.
A cold seep is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. The "cold" is relative to the very warm conditions of a hydrothermal vent. Cold seeps constitute a biome supporting several endemic species.
Soft-shell clams or sand gaper, scientific name Mya arenaria, popularly called "steamers", "softshells", "piss clams", "Ipswich clams", or "Essex clams", are a species of edible saltwater clam, a marine bivalve mollusk in the family Myidae.
Nuculidae is a family of small saltwater clams in the order Nuculida. Species in this family are commonly known as nut clams.
The ocean quahog is a species of edible clam, a marine bivalve mollusk in the family Arcticidae. This species is native to the North Atlantic Ocean, and it is harvested commercially as a food source. This species is also known by a number of different common names, including Icelandic cyprine, mahogany clam, mahogany quahog, black quahog, and black clam.
Chicoreus brevifrons, common name the West Indian murex, is a species of predatory sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails.
Cerithium litteratum is a species of sea snail, a marine gastropod mollusk in the family Cerithiidae.
Solemya velum, the Atlantic awning clam, is a species of marine bivalve mollusc in the family Solemyidae, the awning clams. This species is found along the eastern coast of North America, from Nova Scotia to Florida and inhabits subtidal sediments with high organic matter (OM) content and low Oxygen, such as salt ponds, salt marshes, and sewage outfalls.
Nucula proxima, commonly known as the Atlantic nut clam, is a marine bivalve mollusc in the family Nuculidae. It can be found along the Atlantic coast of North America, ranging from Nova Scotia to Texas, including Bermuda.
Noetia ponderosa, or the ponderous ark clam, is a marine clam in the family Noetiidae.
Limaria pellucida, the Antillean file shell, is a species of bivalve mollusc in the family Limidae. It can be found along the Atlantic coast of North America, ranging from North Carolina to the West Indies.
Codakia orbicularis, or the tiger lucine, is a species of bivalve mollusc in the family Lucinidae. It can be found along the Atlantic coast of North America, ranging from Florida to the West Indies.
Arcinella cornuta, or the Florida spiny jewelbox clam , is a marine species of bivalve mollusc in the family Chamidae. It can be found along the coast of North Carolina to Florida, Gulf of Mexico, Caribbean Central America, and Venezuela.
Pitarenus cordatus, or the cordate venus clam, is a species of bivalve mollusc in the family Veneridae. It can be found throughout the Gulf of Mexico and the Florida Keys.
Pinctada longisquamosa, sometimes called scaly pearl osters, are a small species of pearl oyster found in the western Atlantic. They are distinguished by unique prismatic shell structures which protrude from the outer shell.
Stewartia floridana is a bivalve of the family Lucinidae that is chemosymbiotic with sulfur-oxidizing bacteria.
Codakia distinguenda, the elegant lucine, is a species of marine bivalve mollusc. It was first described to science in 1872 by George Washington Tryon Jr.
Megapitaria squalida, the chocolate clam, is a species of bivalve mollusc in the family Veneridae. It was first described to science by George Brettingham Sowerby, a British conchologist, in 1835. The type specimen was collected by Hugh Cuming.
Cardites floridana, or the Broad-ribbed Carditid, is a marine clam in the family Carditidae. It can be found along the coasts of Florida, Central America, South America and the Gulf of Mexico.
Panopea bitruncata is a species of marine bivalve commonly known as the Atlantic geoduck or Atlantic geoduck clam. These clams like their more famous Pacific relative P. generosa have an enlarged siphon that can extend to great lengths or contract to just barely poke out of the shell. They are generally smaller in comparison to the Pacific species though still constitute a sizable mollusc as they cannot fully retract their siphon.
