Scissurellidae, sometimes known by thecommon namelittle slit snails, are ataxonomicfamily of minutesea snails,marinegastropodmolluscs ormicromolluscs in the cladeVetigastropoda (according to thetaxonomy 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.
Scissurellids occur world-wide, from theintertidal zone down to theabyssal depths, including aroundhydrothermal vents.
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] Themonophyly of the family is questionable.[3]
In 2003, there were about twenty-five genera divided into five subfamilies (Scissurellinae,Anatominae,Sutilizoninae,Temnocinclinae,Larocheinae) .[4] Three of these subfamilies were later updated to family level.
According to thetaxonomy of the Gastropoda by Bouchet & Rocroi, 2005), this family consisted of the two following subfamilies :
However Geiger (2009)[5] elevated Depressizoninae to the family rank asDepressizonidae.
Genera in the family Scissurellidae include:[6][7][8][9]
