The Pteriida are an order of large and medium-sized marine bivalve mollusks. It includes five families, among them the Pteriidae (pearl oysters and winged oysters). [1] In 2010, a new proposed classification system for the Bivalvia was published by Bieler, Carter & Coan, revising the classification of the Bivalvia, including the suborder Pteriida.

mollusk, any soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body. Along with the insects and vertebrates, it is one of the most diverse groups in the animal kingdom, with nearly 100,000 (possibly as many as 150,000) described species.

Pterioida is an extant order of stationary low-level epifaunal suspension feeders.

The list of species of Pterioida order. The Pteriida are an order of large and medium-sized marine bivalve mollusks. It includes five families, among them the Pteriidae (pearl oysters and winged oysters). ...

Pteridae, the wing oysters, comprises 12 species and 3 genera. Family Malleidae includes 5 species and 2 genera, and Isognomonidae contains 5 species, 3 varieties and one genus. The genera of Pteriidae have traditionally been defined by shell shape (Hertlein and Cox, 1969; Hayes, 1972; Habe, 1977; Oliver, 1992; Lamprell and Healy, 1998).

We describe and summarize the myalinids from Lower and Middle Permian reef and near-reef settings and infer living habits as either epifaunal or semi-infaunal byssally attached suspension feeders. The six myalinid species described are exceptionally preserved as silica pseudomorphs.

Nov 8, 2010 · The superfamily Pterioidea is a morphologically and ecologically diverse lineage of epifaunal marine bivalves distributed throughout the tropical and subtropical continental shelf regions. This group includes commercially important pearl culture species and model organisms used for medical studies of biomineralization.

Mar 1, 2005 · To address the problem we have focused our studies on bivalve nacre, specifically in the shells of the order Pterioida. Briefly, bivalves of the order Pterioida are inequilateral (the umbones being situated anteriorly), monomyarians and inequivalves (except for the pen shells, the Pinnoidea), with the right valve usually less convex than the left.

A family-level Tree of Life for bivalves based on a Sanger-sequencing approach.

Pterioidea is a superfamily of epifaunal marine bivalves mostly inhabiting continental shelf regions of tropical and subtropical oceans. The superfamily includes the economically-important saltwater pearl oysters as well as the oddly shaped hammer oysters (neither of which, however, is considered a true oyster).
