Shell description

This family of snails have small shells which lose their apical whorls as they continue to grow, giving the shells a truncated and cylindrical appearance.

Subfamilies

The family Truncatellidae consists of two subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

  • subfamily Truncatellinae Gray, 1840
  • subfamily Geomelaniinae Kobelt & Möllendorff, 1897
  • Genera

    Genera within the family Truncatellidae include:

    Truncatellinae

  • Truncatella Risso, 1826 - type genus of the family Truncatellidae
  • Geomelaniinae

  • Geomelania L. Pfeiffer, 1845 - type genus of the subfamily Geomelaniinae
  • subfamily ?

  • Taheitia Adams, 1863

    Snails in this family are found in marine coastal environments, near or just above the high tide line on stones and pebbles, fine sediments and decomposing vegetation.
