In taxonomy, binomial nomenclature, also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name, or a scientific name; more informally it is also historically called a Latin name. In the ICZN, the system is also called binominal nomenclature, "binomi'N'al" with an "N" before the "al", which is not a typographic error, meaning "two-name naming system".
Sphaerius is a genus of beetles in the family Sphaeriusidae, comprising 18 species. It is one of the two extant genera in the family, the other being Bezesporum. They are typically found along the edges of streams and rivers, where they feed on algae; they occur on all continents except Antarctica. Three species occur in the United States.
A cockle is an edible marine bivalve mollusc. Although many small edible bivalves are loosely called cockles, true cockles are species in the family Cardiidae.
The hard clam, also known as the round clam, hard-shellclam, or the quahog, is an edible marine bivalve mollusk that is native to the eastern shores of North America and Central America from Prince Edward Island to the Yucatán Peninsula. It is one of many unrelated edible bivalves that in the United States are frequently referred to simply as clams. Older literature sources may use the systematic name Venus mercenaria; this species is in the family Veneridae, the venus clams.
The Arcida is an extant order of bivalve molluscs. This order dates back to the lower Ordovician period. They are distinguished from related groups, such as the mussels, by having a straight hinge to the shells, and the adductor muscles being of equal size. The duplivincular ligament, taxodont dentition, and a shell microstructure consisting of the outer crossed lamellar and inner complex crossed lamellar layers are defining characters of this order.
The Veneridae or venerids, common name: Venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources.
Venus is a genus of small to large saltwater clams in the family Veneridae, which is sometimes known as the Venus clams and their relatives. These are marine bivalve 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.
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently.
Tucetona laticostata, or the large dog cockle, is a salt water clam or marine bivalve mollusc in the family Glycymerididae.
Babyloniidae is a taxonomic family of predatory sea snails, marine gastropod mollusks unassigned within the superfamily Neogastropoda.
The Myuchelys is a genus of turtles, the Australian saw-shelled turtles, in the family Chelidae and subfamily Chelodininae. They inhabit the headwaters and tributaries of rivers within their range and this led to the name Myuchelys, which is formed from the Aboriginal word myuna meaning clear water and the Greek chelys meaning turtle. They have a short neck and the intergular scute completely separates the gular scutes. They have no alveolar ridge separating them from the snapping turtles of the genus Elseya.
Tucetona isabellae is a species of clam that was described in 2011 by Paul Valentich-Scott, Curator of Malacology at the Santa Barbara Museum of Natural History (SBMNH), and Elizabeth A. R. Garfinkle, 11th grade student at San Roque High School.
Tucetona bicolor is a species of dog cockle. Its shell is subtrigonal with 39 radial ribs. The ribs have with moderately shallow, very narrow interspaces, with very fine, very closely spaced commarginal ribs. The hinge plate is moderately wide and curved.
Tucetona pectinata, or the comb bittersweet, is a species of bivalve mollusc in the family Glycymerididae.
Glycymeris, common name the bittersweet clams, is a genus of saltwater clams, marine bivalve molluscs in the family Glycymerididae.
Hinge teeth are part of the anatomical structure of the inner surface of a bivalve shell, i.e. the shell of a bivalve mollusk. Bivalves by definition have two valves, which are joined together by a strong and flexible ligament situated on the hinge line at the dorsal edge of the shell. In life, the shell needs to be able to open slightly to allow the foot and siphons to protrude, and then close again, without the valves moving out of alignment with one another. To make this possible, in most cases the two valves are articulated using an arrangement of structures known as hinge teeth. Like the ligament, the hinge teeth are also situated along the hinge line of the shell, in most cases.
Glycymeris aspersa, common name the clothed bittersweet, is a species of saltwater clam, a marine bivalve mollusc in the family Glycymerididae, the bittersweets.
Tucetona is a genus of saltwater clams, marine bivalve molluscs in the family Glycymerididae, the bittersweet clams. Unlike other genera in the family, Tucetona species have a ribbed shell.
Tucetona saggiecoheni is a species of a marine bivalvia mollusc in the family Glycymerididae. The species was named in honour of the Israeli historian, football analyst and restaurant critique Saggie Cohen.
