The dye will turn indigo blue, similar to the color of blue jeans, if exposed to sunlight before the dye sets. 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'. Shells of the rock murex, Trunculariopsis trunculus (Linn, 1758), used in the purple dye industry in ancient maritime civilizations, have been found in. North Africa, Egypt, woven tapestry using wool and linen, dated to 600- 899 AD purple yarns possibly dyed with Murex brandaris or Murex trunculus sea snails.

One of the dye's main chemical ingredients is red dibromo-indigotin, the main component of tyrian purple or tekhelet. 500-599 AD purple yarns possibly dyed with Murex brandaris or Murex trunculus sea snails. Ancient Mediterranean cultures, including the Minoans, Canaanites/Phoenicians, Hebrews, and classical Greeks created dyes from the snails. This sea snail is historically important because its hypobranchial gland secretes a mucus used to create a distinctive purple-blue indigo dye. Murex snails and shells have been probably used in jewels. Fossilized shells have been found in Morocco, Italy, and Spain. Shellfish purple, also known as Tyrian purple and royal purple, has a long history. Tyrian purple is an ancient and rare dye that is derived from the murex snail, which is found in the Mediterranean Sea. purple was produced primarily from three species of sea mollusks of the Muricidae family, which were common in the Mediterranean Sea: Hexaplex trunculus (Murex. The snail appears in fossil records dating between the Pliocene and Quaternary periods (between 3.6 and 0.012 million years ago). What is peculiar about this specific species is that they show no preference for the size of their prey, regardless of their hunger levels. A Tunisian history enthusiast is making dye from sea snail shells inspired by a school project decades ago on ancient Carthage and the purple coloring that brought. This species is a group of opportunist predatory snails that are known to attack their prey in groups. It is included in the subgenus Trunculariopsis. Hexaplex trunculus (previously known as Murex trunculus, Phyllonotus trunculus, or the banded dye-murex) is a medium-sized sea snail, a marine gastropod mollusk in the family Muricidae, the murex shells or rock snails.
