The great majority of species within this family are only known as fossils. The few species which are still extant are sometimes termed "living fossils". [1]

Taxonomy

2005 taxonomy

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

• Neritopsinae Gray, 1847
• † Naticopsinae Waagen, 1880 - synonym: Hologyridae Kittl, 1899
• † Paffrathiinae Heidelberg, 2001

2007 taxonomy

Bandel (2007)^[1] have established two new subfamilies. But he recognizes Naticopsinae at family level as Naticopsidae with newly created subfamilies in it.^[1]

• Neritopsinae Gray, 1847
• † Paffrathiinae Heidelberg, 2001 - to be clarified if Bandel recognized this family.^{[clarification needed]} It is not mentioned in his work Bandel (2007).^[1]
• † Cassianopsinae Bandel, 2007^[1]
• † Colubrellopsinae Bandel, 2007^[1]
