Murex Megapex

''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".Houart, R.; Gofas, S. (2010). Murex Linnaeus, 1758.

The common name murex is still used for many species in the family Muricidae which were originally given the Latin generic name ''Murex,'' but have more recently been regrouped into newer genera. ''Murex'' was used in antiquity to describe spiny sea snails, especially those associated with the production of purple dye''. Murex'' is one of the oldest classical seashell names still used by the scientific community.

Aristotle described these mollusks in his ''History of Animals'' using the Greek term πορφύρα (''porphyra'').

Etymology

The term murex originates from the Latin word ''mūrex,'' likely related to the Greek word μύαξ (''myax''), meaning sea mussel. The connection between these terms suggests a shared linguistic root, possibly linked to the Greek word μῦς (''mys''), meaning "mouse," due to the perceived resemblance between the shape of certain mollusks and mice.

Fossil records

This genus is known in the fossil records from the Cretaceous to the Quaternary (age range: from 125.45 to 0.0 million years ago). Fossils of species within this genus have been found all over the world. There are about 25 known extinct species.Fossilworks

Distribution

''Murex'' is solely an Indo-Pacific genus, as demonstrated by Ponder & Vokes (1988). The species from the western Atlantic that were formerly considered to belong to the genus ''Murex'' are now placed in the genus ''Haustellum''.

Habitat

Most ''Murex'' species live in the intertidal or shallow subtidal zone, among rocks and corals.

Shell description

This genus includes many showy members, their elongate shells highly sculptured with spines or fronds. The inner surfaces of their ornate shells are often brightly colored.

Human use

Costly and labor-intensive dyes Tyrian purple (or "royal purple") and tekhelet were historically made by the ancient Phoenicians, using mucus from the hypobranchial gland of two species commonly referred to as "murex", ''Murex brandaris'' and ''Murex trunculus'', which are the older names for ''Bolinus brandaris'' and ''Hexaplex trunculus''. This dye is a rare animal-produced organobromine compound, which the snails make using a specific bromide peroxidase enzyme that operates on dissolved bromide in sea water.

This dye was used in royal robes, other kinds of special ceremonial or ritual garments, or garments indicating high rank. It is hypothesised that the dye was the same dye as that which featured prominently in the ancient Temple in Jerusalem, the clothing of the High Priest of Israel officiating there; it is sometimes still used by Jews today in the ritual fringes (tzitzit) on four-cornered garments. A consensus has yet to be reached regarding the Biblical source of the "blue" dye, though the latest archeological research on dyes in this region indicates that it was indeed the Murex trunculus snail that was used for the famous tekhelet ancient dye.

Species

The genus ''Murex'', as originally defined by Linnaeus, encompassed many taxa that are now placed elsewhere in the superfamily Muricoidea. During the 19th century, the definition of ''Murex'' was restricted by Lamarck and his contemporaries first to species in the family Muricidae, and then was limited even further to the subfamilies Muricinae and Ocenebrinae. Malacologists of the 19th century including Kiener, Reeve, Küster & Kobelt and Sowerby treated all muricoid forms as belonging to ''Murex''. This is the main reason why ''Murex'' has so many synonyms.
