Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.[1]

Description

Turbinidae have a strong, thick calcareous operculum readily distinguishing them from the somewhat similar Trochidae or top snails, which have a corneous operculum. This strong operculum serves as a passive defensive structure against predators that try to enter by way of the aperture or that would break the shell at the outer lip. These operculum are rounded ovals that are flat with a swirl design on one side and domed on the other. They are known as Pacific cat's eye or Shiva eye shells or mermaid money, and are used for decorative purposes.

Etymology

The common name turban snail presumably refers to the shell's similarity in appearance to a turban. However, the scientific name Turbinidae is based on the genus name Turbo, which is Latin for spinning top, a child's toy. The word turbine has a similar derivation.

Taxonomy

Previously they were classified in the subclass Prosobranchia, in the order Archaeogastropoda in the superfamily Trochacea. Trochaecea is now a synonym for the superfamily Trochoidea. However, this is a quite ancient group of gastropods, probably originating in the Permian period 298 to 250 million years ago.[2] They have typical primitive characters like the nacreous interior of the shell.

2005 taxonomy

Turbinidae belongs to superfamily Turbinoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

This family consists of eight following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

  • Turbininae Rafinesque, 1815 - synonyms: Senectinae Swainson, 1840; Imperatorinae Gray, 1847; Astraliinae H. Adams & A. Adams, 1854; Astraeinae Davies, 1935; Bolmidae Delpey, 1941
  • Angariinae Gray, 1857 - synonym: Delphinulinae Stoliczka, 1868
  • Colloniinae Cossmann, 1917
    • tribe Colloniini Cossmann, 1917 - synonym: Bothropomatinae Thiele, 1924 (inv.); Homalopomatinae Keen, 1960; Petropomatinae Cox, 1960
    • tribe † Adeorbisinini Monari, Conti & szabo, 1995
    • tribe † Crossostomatini Cox, 1960
    • tribe † Helicocryptini Cox, 1960
  • Moellerinae Hickman & McLean, 1990
  • † Moreanellinae J. C. Fischer & Weber, 1997
  • Prisogasterinae Hickman & McLean, 1990 - synonym: "Prisogastrinae" in Bouchet & Rocroi (2005) is a spelling error.[3]
  • Skeneinae W. Clark, 1851 - synonym: Delphinoideinae Thiele, 1924
  • Tegulinae Kuroda, Habe & Oyama, 1971

2008 taxonomy

Astraea rugosa (Linnaeus, 1767), a fossil turbinid from the Pliocene of Cyprus.

Turbinidae was redefined and moved to the redefined superfamily Trochoidea according to Williams et al. (2008):[4] Angariidae was elevated to family level, Colloniinae was elevated to family Colloniidae within Phasianelloidea,[4] Margaritinae was moved to Turbinidae from Trochidae.[4]

This family consists of five following subfamilies according to Williams et al. (2008):[4]

  • Turbininae Rafinesque, 1815 - synonyms: Senectinae Swainson, 1840; Imperatorinae Gray, 1847; Astraliinae H. Adams & A. Adams, 1854; Astraeinae Davies, 1935; Bolmidae Delpey, 1941
  • Skeneinae W. Clark, 1851 - synonym: Delphinoideinae Thiele, 1924 (upgraded to the rank of family Skeneidae)
  • Margaritinae Thiele, 1924 - tribes are sensu taxonomy of the Gastropoda by Bouchet & Rocroi, 2005) - upgraded to the rank of family Margaritidae
    • tribe Margaritini Thiele, 1924 - synonym: Margaritinae Stoliczka, 1868 (inv.)
    • tribe Gazini Hickman & McLean, 1990
    • tribe Kaiparathinini Marshall, 1993
  • Tegulinae Kuroda, Habe & Oyama, 1971: upgraded to the rank of family Tegulidae Kuroda, Habe & Oyama, 1971
  • Prisogasterinae Hickman & McLean, 1990

The following subfamilies (sensu Bouchet & Rocroi (2005) classification of subfamilies in Turbinidae) were kept in Turbinidae:

  • Moellerinae Hickman & McLean, 1990 - Moelleria was not included in the molecular studies performed in 2010.[4][5]
  • † Moreanellinae J. C. Fischer & Weber, 1997

Distribution

Turbinids occur in shallow and deep waters. The family has a large distribution, from the tropics to the polar regions, but most of the species live in tropical and subtropical shallow waters.

Genera
