Cetoconcha Elegans
''Cetoconcha elegans'' is a species of saltwater clams in the genus '' Cetoconcha''. It is known from seamount A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abru ...s and knolls.

Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poromyidae
Poromyidae is a family of saltwater clams, marine bivalve molluscs in the order Anomalodesmata. The genus ''Dilemma'', described in 2008, is remarkable for being a predator of copepods, which is very unusual for a sessile mollusc. Genera and species Genera and species within the family Poromyidae include: *'' Cetomya'' Dall, 1889 *'' Dermatomya'' Dall, 1889 **'' Dermatomya buttoni'' Dall, 1916 ** '' Dermatomya mactroides'' ( Dall, 1889) * ''Dilemma'' Leal, 2008 *'' Lissomya'' Krylova, 1997 * '' Poromya'' Forbes, 1844 ** '' Poromya albida'' Dall, 1886 ** '' Poromya beringiana'' ( Dall, 1916) ** '' Poromya elongata'' Dall, 1886 ** ''Poromya granulata'' (Nyst and Westendorp, 1839) ** '' Poromya houbricki'' Bernard, 1989 ** '' Poromya laevis'' E.

Bivalves Described In 1991
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. They include 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. The shell of a bivalve is composed of calcium c ...
