Murex is a genus of medium to large sized predatory tropical sea snails. These are carnivorous marine gastropod molluscs in the family Muricidae, the murexes or rock snails.
The common name "murex" is also used for a large number of species in the family Muricidae, most of which in the past were originally given the Latin generic name Murex, but most of which have now been grouped in other newer genera.
The word murex was used by Aristotle in reference to these kinds of snails, thus Murex is arguably one of the oldest classical shell names still in use by the scientific community.
