Murex is a genus of marine mollusks known for their distinctive, spiky shells. These sea snails are primarily found in warm, shallow waters and are part of the family Muricidae. Murex species are often recognized for their unique shell shapes and vibrant colors, making them popular among collectors. Historically, Murex snails were significant in the production of Tyrian purple, a valuable dye used in ancient times. This dye was extracted from the snail's gland and was highly prized in ancient Rome and Phoenicia for its rich color, often associated with royalty and nobility.
