Velutinidae is a family of small sea snails, marine gastropod molluscs in the clade Littorinimorpha.[1][2][3]
Description
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 dorid sea slugs rather than sea snails, but anatomically quite different. They are readily distinguished by the anterior siphon and typically snail-like, tentacle-bearing head beneath the anterior mantle. There are no rhinophores (chemosensory tentacles) or dorsal circlet of gills.
The shell is present but is completely internal. It is covered by a fleshy mantle. The ventral surface features a distinct foot and a head bearing tentacles with basal eyes. The anterior of the dorsal surface (notum) is indented along the midline, forming a short siphon. The mantle is relatively firm but has a somewhat gelatinous texture, appearing mostly smooth. The internal shell resembles an ear, being thin and fragile. [4]
Taxonomy
The following two subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005):[1]
- Subfamily Velutininae J. E. Gray, 1840 - synonyms: Marseniidae Leach in Gray, 1847; Marsenininae Odhner, 1913; Capulacmaeinae Golikov & Gulbin, 1990; Onchidiopsinae Golikov & Gulbin, 1990 (n.a.); Marseniopsidae Badel, 1993 (n.a.)
- Subfamily Lamellariinae A. D. d'Orbigny, 1841 - synonyms: Coriocellidae Troschel, 1848; Sacculidae Thiele, 1929 (inv.); Pseudosacculidae Kuroda, 1933
