The Nassariidae, Nassa mud snails (USA), or dog whelks (UK), are a taxonomic family of small to medium-sized sea snails, marine gastropod mollusks in the clade Neogastropoda.
"Dog whelk" also refers to Nucella lapillus .
These snails have rounded shells with a high spire, an oval aperture, and a siphonal notch.
This family of snails is found worldwide.
These snails are found mostly in shallow water, on sandy or muddy substrates, often intertidally, but sometimes in deep water. They can be present in very large numbers in suitable habitat.
Nassariidae are primarily active and lively scavengers.
The family Nassariidae is closely related to the family of the true whelks, Buccinidae, because of their shared characteristics in the anatomy of the species in these families, [2] [3] [4] [5] ), i.e. a long proboscis, the loss of glandular dorsal folds, and a smaller gland of Leiblein (a dorsal venom gland in the mid-oesophagus).
According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Nassariidae consists of four subfamilies:
Kantor et al. (2022) used molecular data to revise the classification of the Buccinoidea superfamily, proposing 20 taxa of family rank and 23 subfamilies. [7] This included the description of a new subfamily of Nassariidae:
Photinae Gray, 1857 was recognized
A new subfamily Anentominae was recognized.
Genera within the family Nassariidae include: [9] [10]
The operculum is ovate, acute and with an apical nucleus; the margin is entire or serrated.
The eyes in some of the genera are near the base of the tentacles, in others near their middle, and are sometimes wanting.
The aperture of the shell is either truncate, or with a short recurved siphonal canal, and the inner lip is usually callous and spreading over the body whorl. [11]
