The Noetiidae are a family of mussels from the order of the Arcida . There are currently around 16 genera with 35 recent species in the Noetiidae family. The Noetiidae have been known since the Lower Cretaceous.

features

The housings, which are of the same flap and are mostly small, are oval, oblong-egg-shaped or oblong-trapezoidal to obliquely triangular in outline. They usually have an adult size of five to 30 millimeters, with a few species even up to 8 centimeters. The vertebra is shifted forward, it is more or less far in the front half of the housing. Due to the strongly curled vertebrae, the dorsal field can be quite wide when viewed from above. When the flaps are closed, the housings have little or no gap at which the byssus can escape. A sharp keel runs from the vertebra to the corner of the posterior and ventral edges.

The lock is taxodont with numerous uniform teeth. The ligament can be narrow or wide, depending on the size of the dorsal field. It can be prosodetic (in front of the vertebra), amphidistic (in front of and behind the vertebra), or opisthodetic (behind the vertebra). It has strips of elastic material running transversely to the dorsal axis, embedded in fibrous material that is in contact with the shell.

The housing is extremely thick. The ornamentation consists of radial ribs and / or concentric growth strips that can form a net-like pattern. The periostracum is generally drawn out into hairs or villi. The surface line is entire without indentation. There are always two sphincters that are approximately the same size. Low rims are formed around the muscle attachment points.

Geographical distribution and habitat

The species of the family Noetiidae occur almost exclusively in tropical and subtropical seas worldwide. Only one species penetrates into moderate latitudes. They mostly live in the tidal range to shallow water. There they are attached to corals and hard substrates with byssus, or live hidden in crevices in the rock. Others dig freely (without byssus attachment) in soft sediments of shallow water, including in estuarine areas.

The representatives of the family Noetiidae are separate sexes. A planktotrophic larva has been found in at least some species.

Taxonomy

The taxon was proposed as the subfamily Noetiinae by Ralph Bentley Stewart in 1930. It is therefore also available as a family name. Bouchet & Rocroi (2011) lead the taxon as a family within the superfamily Arcoidea, Carter et al. (2011) treat it as a subfamily of the ark mussels (Arcidae). The World Register of Marine Species assigns the following genera to the family:
