Odostomia is the most speciose genus of minute sea snails, pyramidellid gastropod mollusks. This genus is currently placed in the family Pyramidellidae in the subfamily Odostomiinae. There are several hundred species in the genus (Schander et al. 1999) [1][2][3]

Distribution

The genus Odostomia is common in all oceans from the tropics to the polar regions. It is mainly known from coastal areas and sandy shores, and is less common in the deep sea.

Description

Most species are have minute shells, usually between 2 mm and 5 mm. The apex of the ovate-conical shell is rather obtuse or nipple-shaped. They are variously sculptured, usually with a microsculpture.The aperture is suboval with the peristome incomplete behind. There is usually a tooth-like fold on the columella. [4]

Life habits

The members of Odostomia are ectoparasites on other molluscs, and polychaetes. First they pierce the body wall with the buccal stylet and then feed on them by sucking blood with their buccal pump. They have become a pest of oysters, mussels, scallops and slipper limpets. [5] Most of the Odostomia species are host-specific, only a few are not. Odostomia scalaris MacGillivray, 1843 is an ectoparasite on a wide range of hosts but especially known as a pest of mussels. Odostomia turrita Hanley, 1844 has been found on the European lobster Homarus gammarus (Linnaeus, 1758). [6]
