Potamididae, common name potamidids (also known as horn snails or mudwhelks) are a family of small to large brackish water snails that live on mud flats, mangroves and similar habitats.[1] They are amphibious gastropod molluscs in the superfamily Cerithioidea.
Traditionally, potamidids and batillariids have been confused because they have similar shells and they live in similar environments. For many fossil taxa the family assignment to either of these two families is still unresolved or controversial.[1]
According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Potamididae has no subfamilies.[2]
Ecology and Distribution
Most of the 29 living species of Potamididae show a close association with mangroves. Most species live on mudflats, but some also climb mangrove trees. The distribution of Potamididae includes the Indo-West Pacific, the eastern Pacific and the Atlantic Ocean.[1]
Genera
Six living and a number of fossil genera are currently recognized:[1]
Recent genera:[1]
- Cerithidea Swainson, 1840
- Cerithideopsis Thiele, 1929
- Cerithideopsilla Thiele, 1929; containing the only recent species previously assigned to Potamides, C. conica.
- Telescopium Montfort, 1810
- Terebralia Swainson, 1840
- Tympanotonos Schumacher, 1817
Fossil genera (fossils are difficult to differentiate from other cerithioideans, such as the Batillariidae):
- † Bittiscala Finlay & Marwick, 1937[3]
- † Canaliscala Cossmann, 1888[3]
- † Exechestoma Cossmann, 1899[3]
- † Gantechinobathra Kowalke, 2001[3]
- † Harrisianella Olson 1929[3]
- † Potamides Brongniart, 1810 - type genus, its type species is extinct[2] and the whole genus is extinct,[1] synonym: Pirenella Gray, 1847[4]
- † Vicarya Vicarya d'Archiac & Haimes, 1854[3]
- † Vicaryella Yabe & Hatai, 1938[3]
