Cyrenoidea is a superfamily of freshwater bivalves in the order Venerida. [2]
There are approximately 60 or more living species of the superfamily, which can be found in marine, brackish, and freshwater environments. [2]
The following families are recognised in the superfamily Cyrenoidea: [3]
Orthogastropoda was a major taxonomic grouping of snails and slugs, an extremely large subclass within the huge class Gastropoda according to the older taxonomy of the Gastropoda.
Venerida is an order of mostly saltwater but also some freshwater bivalve molluscs. This order includes many familiar groups such as many clams that are valued for food and a number of freshwater bivalves.
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Heteroconchia is a taxonomic infraclass of diverse bivalve molluscs, belonging to the subclass Autobranchia.
Tegula is a genus of small to medium-sized sea snails, marine gastropod molluscs in the family Tegulidae.
The Trochidae, common name top-snails or top-shells, are a family of various sized sea snails, marine gastropod molluscs in the subclass Vetigastropoda. This family is commonly known as the top-snails because in many species the shell resembles a toy spinning top.
Calliostomatidae is a family of sea snails within the superfamily Trochoidea and the clade Vetigastropoda.
Xenophoridae, commonly called carrier shells, is a family of medium-sized to large sea snails, marine gastropod mollusks in the clade Littorinimorpha.
Cyrenoididae is a taxonomic family of saltwater clams, marine bivalve mollusks in the superfamily Cyrenoidea.
Amathinidae, is a taxonomic family mostly consisting of small and minute sea snails, marine heterobranch gastropod molluscs or micromolluscs in the superfamily Pyramidelloidea.
Lottiidae is a family of sea snails, specifically true limpets, marine gastropod mollusks in the superfamily Lottioidea and the clade Patellogastropoda.
Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda.
The Achatinoidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the suborder Achatinina.
Olivoidea is a taxonomic superfamily of minute to medium-large predatory sea snails, marine gastropod mollusks in the order Neogastropoda.
Costellariidae sometimes called the "ribbed miters" is a taxonomic family of minute to medium-sized predatory sea snails, marine gastropod mollusks. This family of snails is also sometimes referred to as Vexillum miters. The main family of miter shells however is Mitridae, a closely related group.
Pseudolividae is a taxonomic family of medium-sized sea snails, marine gastropod mollusks in the superfamily Olivoidea.
Clavatulidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Conoidea. The family is not well differentiated morphologically.
Cymothoida is the name of a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing.
Angarioidea is a superfamily of small to medium sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
The Ancillariidae is a taxonomic family of sea snails, marine gastropod molluscs in the superfamily Olivoidea. They are gastropods, which belong to the larger group of mollusks. This family is part of the superfamily Cypraeoidea, which includes cowries, a well-known group of sea snails.
