Muricopsinae is a taxonomic subfamily of predatory sea snails, marine gastropod mollusks within the large family Muricidae, the murex snails and rock snails. [1]
A study, released in September 2010, showed that the subfamily Muricopsinae is polyphyletic [2]
This subfamily has been delineated based on the characteristics of the operculum and the radula.
The shell is wide in the middle and tapers at both ends, making it fusiform to biconic. The size of the shell varies in length between 5 mm and 85 mm. Its color is white or brown, covered with subdued shades of brown, orange, red or purple markings. The aperture is broadly oval to almost round and is of variable size. Contrary to the other Muricidae, the siphonal canal, the semi-tubular extension of the aperture, is of moderate length. Like the other murex shells, each convex whorl shows a variable number (four or more) of more or less prominent varices (a thickened axial ridge in the shell), which, in turn, show foliaceous or spinose projections. [3]
The operculum is the same as in the subfamily Muricinae. It is unguiculate, thickened at the margin and depressed and annulate in the middle.
The rachiglossan radula has in each row a three-dimensional rachidian tooth with a raised central cusp and two lateral teeth, as in the subfamily Ocenebrinae.
The genera in this subfamily are distributed worldwide, mainly in tropical and subtropical waters, at depths between 0 and 300 m.
Several genera that were recognized in the past have now become synonyms :
Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, commonly called "murexes" or "rock snails".
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With about 1,600 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized. Numerous subfamilies are recognized, although experts disagree about the subfamily divisions and the definitions of the genera. Many muricids have unusual shells which are considered attractive by shell collectors and by interior designers.
Muricinae is a taxonomic subfamily of predatory sea snails, marine gastropod mollusks within the large family Muricidae, the murex snails and rock snails.
Poirieria is a genus of large predatory sea snails, marine gastropod molluscs in the subfamily Pagodulinae of the family Muricidae, the rock snails.
Muricopsis is a genus of small predatory sea snails, marine gastropod mollusks in the rock snail family, Muricidae.
Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae Monterosato, 1884 should be called Tornidae
The Fasciolariidae, common name the "tulip snails and spindle snails", are a family of small to large sea snails, marine gastropod mollusks in the superfamily Buccinoidea.
Hexaplex is a genus of medium-sized to large sea snails, marine gastropod mollusks in the subfamily muracinae of the family Muricidae, the murex shells or rock snails.
Pygmaepterys adenensis is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.

Aspella is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Favartia is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. It is known for its crystalline shell.
Haustellum is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. Like many other genera within the Muricidae, the genus has been redefined several times.
Murexiella is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
