Scissurellidae, sometimes known by the common name little slit snails, are a taxonomic family of minute sea snails, marine gastropod molluscs or micromolluscs in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[1]

The shells of these snails vary in adult size from less than 6 mm to less than 1 mm.

Distribution[]

Scissurellids occur world-wide, from the intertidal zone down to the abyssal depths, including around hydrothermal vents.

Taxonomy[]

There are about 169 living described species of Scissurellidae, but the diversity of scissurellids is still far from being completely assessed (approximately 60 collected species await description).[2] The monophyly of the family is questionable.[3]

In 2003, there were about twenty-five genera divided into five subfamilies (Scissurellinae, Anatominae, Sutilizoninae, , ) .[4] Three of these subfamilies were later updated to family level.

According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005), this family consisted of the two following subfamilies :

  • Scissurellinae Gray, 1847 - synonym: Depressizoninae Geiger, 2003; now accepted with family rank Scissurellidae.
  • Larocheinae Finlay, 1927: now elevated to family rank as Larocheidae.

However Geiger (2009)[5] elevated Depressizoninae to the family rank as Depressizonidae.

Genera[]

Genera in the family Scissurellidae include:[6][7][8][9]
