Velutinidae is a family of small sea snails, marine gastropod molluscs in the clade Littorinimorpha.[1][2][3]
The shell of these animals is very thin and delicate, and internal, completely covered by the mantle (which has fused lobes) so the appearance of these animals more closely resembles that of sea slugs rather than sea snails.
The following two subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005):[1]
Genera within the family Velutinidae include:
Subfamily Lamellariinae A. D. d'Orbigny, 1841
Subfamily Velutininae Gray, 1840
