Purpura is a genus of sea snails, marine gastropod mollusks in the subfamily Rapaninae of the family Muricidae, the murex snails or rock snails. [1]
Not to be confused with PurpuraJousseaume, 1880, a synonym of Bolinus Pusch, 1837 [2]
The genus Purpura is characterised by having large shells with large apertures, a concave columella and no external calcitic layer. The rachidian teeth have prominent marginal denticles. [3]
The shell is oblong-oval, the body whorl large. The spire is short. The aperture is ovate, large, with an oblique channel or groove at the fore part. The columella is flattened. The outer lip is simple. [4]
The Purpura and related genera inhabit the seas both of temperate and tropical climates. Many species produce a fluid which gives a dull crimson dye, whence their name of purple shells. Their egg-cases are membranous, oval or spheroidal, sometimes solitary, sometimes united in masses, each sac containing many embryos.
Species within the genus Purpura include:
In the course of time, several hundred species were included in the genus Purpura.
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 over 1,700 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.
