Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=994962 on 2021-02-25 This is a large and diverse group of new world snails, ranging in distribution from Alaska through North America to the West Indies, Central America, and as far south as Argentina. The shells are typically of medium to large size, with no apertural teeth but usually with a reflected apertural lip. Anatomy In the species in this family, the diverticulum may be present or absent. They possess a single dart apparatus with one stylophore (dart sac) and two mucus glands. These snails use the love dart as part of their mating behavior.

In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g.
