Ianthinidae ( 19th century authors used indifferently the spellings Janthina / Ianthina and Janthinidae / Ianthinidae. The nomenclaturally valid name is Janthinidae, but the spelling Ianthinidae has remained sporadically in use throughout the 20th century.)

Janthinidae, common name the purple snails or violet snails, are a family of pelagic sea snails, marine gastropod mollusks in the informal group Ptenoglossa of the clade Hypsogastropoda.

This planktonic group has modified its foot to produce "rafts" of mucus bubbles used in flotation.[1]
