Turbinidae, the turban snails, are a family of small to large marine gastropods. 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.

[edit] 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. Turbine has a similar derivation.

[edit] 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.

[edit] 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

[edit] 2008 taxonomy

Turbinidae was redefined and moved to the redefined superfamily Trochoidea according to Williams et al. (2008):[1] Angariidae was elevated to family level, Colloniinae was elevated to family Colloniidae within Phasianelloidea,[1] Margaritinae was moved to Turbinidae from Trochidae.[1]

This family consists of five following subfamilies according to Williams et al. (2008):[1]

  • 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
  • Margaritinae Thiele, 1924 - tribes are sensu taxonomy of the Gastropoda by Bouchet & Rocroi, 2005)
    • tribe Margaritini Thiele, 1924 - synonym: Margaritinae Stoliczka, 1868 (inv.)
    • tribe Gazini Hickman & McLean, 1990
    • tribe Kaiparathinini Marshall, 1993
  • Tegulinae Kuroda, Habe & Oyama, 1971
  • Prisogasterinae Hickman & McLean, 1990

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

[edit] Genera

The shell of Guildfordia yoka, a deep water turbinid.

Genera in the Turbinidae family include:

Turbininae[5]

Skeneinae[7]

Recent molecular evidence suggests that a number of these genera in Skeneinae probably belong to other families altogether, so many of these assignments must be regarded as provisional.[10][11]

Margaritinae

Tegulinae[13]

Prisogasterinae

Moelleriinae
