Nassariidae
Nassariidae, common name nassa mud snails , or dog whelks , are a taxonomic family of small to medium-sized sea snails, marine gastropod mollusks in the clade Neogastropoda.-Shell description:...

.

Etymology

The name is derived from the Latin word "nassa", meaning a fyke (a bag-shaped fish trap) (fyke being derived from the old Dutch word "fuycke"). Nassarius would then mean "someone who uses a fyke".

Life habits

Most Nassarius species are very active scavenger
Scavenger
Scavenging is both a carnivorous and herbivorous feeding behavior in which individual scavengers search out dead animal and dead plant biomass on which to feed. The eating of carrion from the same species is referred to as cannibalism. Scavengers play an important role in the ecosystem by...

Shell description

The shells of species in this genus have a relatively high spire and a siphonal notch.

Anatomy

, a cooler water snail less suited to tropical marine aquarium temperatures. In aquaria, the Nassarius is considered nearly indispensable for keeping sand beds clean and healthy, as these snails tend to burrow and plow through the upper layer in a conch-like fashion, keeping algae and detritus from building up visibly on the surface.

The shells of various species of Nassarius are popular with shell collectors, and are sometimes used in jewelry and other forms of decoration.

Taxonomy

The genus Nassarius has traditionally been subdivided into several subgenera, based on differences in shell morphology, especially the sculpture
Sculpture (mollusc)
The sculpture of a mollusc shell is the three-dimensional ornamentation on the outer surface, as distinct from the basic shape of the shell itself or colouration. Sculpture may be concave as well as convex. Sometimes it has microscopic detail. Sculpture refers to the calcareous outer layer, not the...

 : Aciculina, Alectrion, Allanassa, Nassodonta, Niotha, Plicarcularia, Profundinassa, Pygmaeonassa, Telasco, and Zeuxis. However, this division is difficult to define, resulting in much confusion. Even phylogenetic analysis shows that the division into these subgenera appears to be uncertain and unreliable. There seem to be two groups within the genus Nassarius with the closest relationship between the subgenera Zeuxis and Telasco. Even the species within the subgenus Plicarcularia do not belong to a single clade
Clade
A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...

. In the end, the molecular phylogeny did not match the previous morphological phylogeny.

Species

In the course of time, more than 800 names have been allocated to species in the genus Nassarius, most of which have become synonyms.
The following species are accepted names according to the World Register of Marine Species
