Iridinidae is a family of medium-sized freshwater mussels, aquatic bivalve mollusks in the order Unionida. [1]
Genera within the family Iridinidae:
Palaeoheterodonta is a subclass of bivalve molluscs. It contains the extant orders Unionida and Trigoniida. They are distinguished by having the two halves of the shell be of equal size and shape, but by having the hinge teeth be in a single row, rather than separated into two groups, as they are in the clams and cockles.
Sphaerium is a genus of very small freshwater clams, aquatic bivalve molluscs in the family Sphaeriidae, known as the fingernail clams. The small clams in this genus are unusual in that many of them, such as Sphaerium corneum, can climb around underwater on aquatic plants, using their long and strong foot.
Mytilidae are a family of small to large saltwater mussels, marine bivalve molluscs in the order Mytilida. One of the genera, Limnoperna, inhabits brackish or freshwater environments. The order has only this one family which contains some 52 genera.
Pisidium is a genus of very small or minute freshwater clams known as pill clams or pea clams, aquatic bivalve molluscs in the family Sphaeriidae, the pea clams and fingernail clams.
Anadara is a genus of saltwater bivalves, ark clams, in the family Arcidae. It is also called Scapharca.
The Plicatulidae are a family of saltwater clams, marine bivalve mollusks, known commonly as kitten's paws or kittenpaws. These bivalves are related to oysters and scallops. The family has a single living genus, Plicatula, with a second, Harpax known from fossils.
Etheriidae is a small family of medium-sized freshwater mussels, aquatic bivalve molluscs in the order Unionida. It contains two monotypic genera.
Chamidae, common name the jewel boxes or jewel box clams, is a taxonomic family of saltwater clams, the marine bivalve mollusks in the order Venerida.
Isognomon is a genus of marine bivalve mollusks which is related to the pearl oysters.
Argopecten is a genus of saltwater clams, or scallops, marine bivalve mollusks in the family Pectinidae.
Atrina seminuda, the half-naked pen shell, is a species of bivalve mollusc in the family Pinnidae.
Trigoniida is an order of medium-sized saltwater clams, marine bivalve molluscs. Within the fossil record the occurrence of this order is widespread, ranging from the Devonian Period to Recent.
Glycymeris, common name the bittersweet clams, is a genus of saltwater clams, marine bivalve molluscs in the family Glycymerididae.
Chama is a genus of cemented saltwater clams, marine bivalve molluscs in the family Chamidae, the jewel boxes.
Glycymeris nummaria is a species of saltwater clam, a marine bivalve mollusc in the family Glycymerididae, the bittersweet clams.
Pseudochama is a species of bivalve mollusc in the family Chamidae.
Thracia phaseolina is a bivalve mollusc in the family Thraciidae.
