Idas is a genus of saltwater clams, marine bivalve molluscs in the family Mytilidae, the mussels.
The World Register of Marine Species lists the following species: [1]
Mytilidae are a family of small to large marine and brackish-water bivalve molluscs in the order Mytilida. One of the genera, Limnoperna, even inhabits freshwater environments. Mytilidae, which contains some 52 genera, is the only extant family within the order Mytilida.
Limatula, the file shells or file clams, is a genus of marine bivalve molluscs in the family Limidae.
Thyasiridae is a family of bivalve molluscs, including the cleft clams, in the order Lucinida.
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.
Verticordiidae is a family of benthic marine bivalves in the superorder Anomalodesmata. These clams range from 2 - 200 millimeters in length and are mainly found in coastal waters surrounding Australia and the Americas, though a few species within this family such as Haliris mediopacifica are found in the middle of the ocean. Verticordiidae is known for being a family of septibranchs, or predatory bivalves, rather than filter feeders. Clams dig vertical burrows in substrate and use papillae around the edges of their inhalant siphons to detect microscopic prey. Some clams in this family, specifically in the genus Trigonulina, have distinct extended circular formations on their shells.
The Cimidae is a taxonomic family of sea snails, marine gastropod mollusks in the infraclass Lower Heterobranchia.
Euspira is a genus of medium-sized sea snails, marine gastropod molluscs in the subfamily Polinicinae of the family Naticidae, the moon snails.
Seguenzia elegans is a species of sea snail, a marine gastropod mollusk in the family Seguenziidae.
Seguenzia is a genus of sea snails, marine gastropod mollusks in the family Seguenziidae.
Moelleria is a genus of sea snails, marine gastropod mollusks in the family Colloniidae.
Ganesa is a genus of sea snails, marine gastropod mollusks in the family Skeneidae.
Skenea is a genus of small to minute sea snails, marine gastropod mollusks in the family Skeneidae.
Perna is a genus of mussels, marine bivalve molluscs in the family Mytilidae.
Krachia is a genus of minute sea snails, marine gastropod molluscs in the family Cerithiopsidae.
Gregariella is a genus of mussels in the family Mytilidae.
Propeamussium is a genus of saltwater clams, marine bivalve mollusks in the order Ostreoida.
