The Nassariidae, Nassa mud snails (US), or dog whelks (UK) are a taxonomic family of small to medium-sized snails, mostly marine gastropod mollusks in the clade Neogastropoda. 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.

Subtaxa

{{As of|2024|November}}, the World Register of Marine Species accepts the following 48 genera, arranged within 7 subfamilies.{{cite WoRMS|title=Nassariidae|id=151|accessdate=26 November 2024}}

Anentominae E. E. Strong, Galindo & Kantor, 2017

Bulliinae Allmon, 1990

Cylleninae Bellardi, 1882

Dorsaninae Cossmann, 1901

Nassariinae Iredale, 1916 (1835)

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.{{Cite book |last=Adams |first=Henry |url=https://www.biodiversitylibrary.org/page/3782650 |title=The genera of recent Mollusca: arranged according to their organization |last2=Adams |first2=Henry |last3=Adams |first3=Arthur |date=1858 |publisher=J.

Taxonomic history

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,(Ponder, 1973The origin and evolution of the Neogastropoda.Malacologia. 1973;12(2):295-338.Systematics of the family Nassariidae (Mollusca: Gastropoda), Bulletin of the Auckland Institute and Museum, 14, 356 p[http://www.mapress.com/mr/content/v25/2005f/n2p098.pdf The molecular phylogeny of the Buccinidae(Caenogastropoda: Neogastropoda) as inferred from the complete mitochondrial 16 S rRNA gene sequences of selected representatives, Molluscan Research 25 (2), pp. 85-98]), 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 consisted of four subfamilies:

  • Nassariinae Iredale, 1916 (1835) - synonyms: Nassinae Swainson, 1835 (inv.); Cyclopsidae Chenu, 1859 (inv.); Cyclonassinae Gill, 1871; Alectrionidae Dall, 1908; Arculariidae Iredale, 1915
  • Bullinae Allmon, 1990 (not recognized by Haitao LI et al., 2010 {{cite journal | url=https://doi.org/10.1007%2Fs00343-010-9031-4 | doi=10.1007/s00343-010-9031-4 | title=Species identification and phylogenetic analysis of genus Nassarius (Nassariidae) based on mitochondrial genes | year=2010 | last1=Li | first1=Haitao | last2=Lin | first2=Duan | last3=Fang | first3=Hongda | last4=Zhu | first4=Aijia | last5=Gao | first5=Yang | journal=Chinese Journal of Oceanology and Limnology | volume=28 | issue=3 | pages=565–572 | bibcode=2010ChJOL..28..565L | s2cid=82834850 | url-access=subscription }})
  • Cylleninae L. Bellardi, 1882
  • Dorsaninae Cossmann, 1901 - synonym: Duplicatinae Muskhelishvili, 1967

In 2006, Photinae Gray, 1857 was recognized.

In 2017, Strong, Galindo & Kantor, 2017 recognized Anentominae as a new subfamily.Strong, E. E., Galindo, L. A., & Kantor, Y. I. (2017). "Quid est Clea helena? Evidence for a previously unrecognized radiation of assassin snails (Gastropoda: Buccinoidea: Nassariidae)". PeerJ 5: e3638. {{doi|10.7717/peerj.3638}}.

Kantor et al. (2022) used molecular data to revise the classification of the Buccinoidea superfamily, proposing 20 taxa of family rank and 23 subfamilies.{{cite journal |author1=Kantor, Yuri I. |author2=Fedosov, Alexander E. |author3=Kosyan, Alisa R. |author4=Puillandre, Nicolas |author5=Sorokin, Pavel A. |author6=Kano, Yasunori |author7=Clark, Roger |author8=Bouchet, Philippe |year=2022 |title=Molecular phylogeny and revised classification of the Buccinoidea (Neogastropoda) |url=https://doi.org/10.1093/zoolinnean/zlab031 |journal=Zoological Journal of the Linnean Society |volume=194 |issue=3 |pages=789–857 |doi=10.1093/zoolinnean/zlab031}} This included the description of a new subfamily of Nassariidae, Tomliniinae.
