Superfamily of gastropods
The Vermetoidea, the worm snails or worm shells, are a taxonomic superfamily of small to medium-sized sea snails, marine gastropod molluscs in the order Littorinimorpha.[1][2]
The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails"
