Murex Echinoides
''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. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138196 on 2011-04-09 The common name murex is still used for many species in the family Muricidae which were originally given the Latin generic name ''Murex'' in the past, but have more recently been regrouped into different newer genera. The word ''murex'' was used by Aristotle in reference to these kinds of snails, thus making it one of the oldest classical seashell names still in use by the scientific community. 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 y ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Muricidae - Murex Spinicosta-000
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 about 1,600 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized.Merle, D., Garrigues, B. & Pointier, J.-P. (2011). ''Fossil and Recent Muricidae of the World, Part Muricinae''. 648 pp., 182 colour plates, ConchBooks, Hackenheim. . 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. Shell description Muricid shells are variably shaped, generally with a raised spire and strong sculpture with spiral ridges and often axial varices (typically three or more varices on each whorl), also frequently bearing spines, tubercles, or blade-like processes.

Haustellum Brandaris
''Bolinus brandaris'' (originally called ''Murex brandaris'' by Linnaeus and also Haustellum brandaris), and commonly known as the purple dye murex or the spiny dye-murex, is a species of medium-sized predatory sea snail, an edible marine gastropod mollusk in the family Muricidae, the murex snails or the rock snails. This species is known in the fossil record from the Pliocene (age range: from 3.6 to 2.588 million years ago). Fossil shells of this species have been found in Cyprus, Spain and Italy. It was used by the Phoenicians in ancient times to extract imperial Tyrian purple dye. Distribution and habitat This snail lives in the central and western parts of the Mediterranean Sea and has been found on isolated coral atoll beaches in the Indian Ocean and South China Sea. It was known since ancient times as a source for purple dye and also as a popular food source under various names, among which ''sconciglio'', from which comes the word '' scungilli''. This species lives on ro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hypobranchial Gland
The hypobranchial gland is a glandular structure which is part of the anatomy of many mollusks, including several different families of gastropods, and also many protobranch bivalves. This gland produces mucus as well as biologically active compounds. The cephalopod ink sac is a modified hypobranchial gland. Anatomy and function ;Gastropods The hypobranchial gland is found in many sea snails, including those in the families Haliotidae, Buccinidae, Mitridae and Costellariidae. It usually presents itself as a thickening of the tissue located in the roof of the animal's mantle cavity. This is in association with parts of the aquatic mollusk anatomy that perform sediment consolidation in these organisms. However, this gland is absent in all terrestrial gastropods except the Neritacea. Its morphology, however, is variable between different groups of snails. Glands with similar functions are present in the Nuculidae, Solenomyidae, Monia, Patellacea, and Loritcata. In the Haliotida ...

Phoenicians
Phoenicia () was an ancient Semitic-speaking peoples, ancient thalassocracy, thalassocratic civilization originating in the Levant region of the eastern Mediterranean, primarily located in modern Lebanon. The territory of the Phoenician city-states extended and shrank throughout their history, and they possessed several enclaves such as Arwad and Tell Sukas (modern Syria). The core region in which the Phoenician culture developed and thrived stretched from Tripoli, Lebanon, Tripoli and Byblos in northern Lebanon to Mount Carmel in modern Israel. At their height, the Phoenician possessions in the Eastern Mediterranean stretched from the Orontes River mouth to Ashkelon. Beyond its homeland, the Phoenician civilization extended to the Mediterranean from Cyprus to the Iberian Peninsula. The Phoenicians were a Ancient Semitic-speaking peoples, Semitic-speaking people of somewhat unknown origin who Ethnogenesis, emerged in the Levant around 3000 BC.

Tekhelet
''Tekhelet'' ( he, תְּכֵלֶת ''təḵēleṯ''; alternate spellings include ''tekheleth'', ''t'chelet'', ''techelet'' and ''techeiles'') is a "blue-violet", "blue", or "turquoise" dye highly prized by ancient Mediterranean civilizations. In the Hebrew Bible and Jewish tradition, it was used in the clothing of the High Priest, the tapestries in the Tabernacle, and the ''tzitzit'' (fringes) affixed to the corners of one's four-cornered garments, including the ''tallit''. Tekhelet is most notably mentioned in the third paragraph of the Shema, quoting . Neither the source nor method of production of ''tekhelet'' is specified in the Bible. According to later rabbinic sources, it was produced exclusively from a marine creature known as the ''Ḥillazon''.Talmudbr>Menachot 44a Tosefta Menachotbr>9:6/ref> Knowledge of how to produce ''tekhelet'' was lost in medieval times, and since then ''tzitzit'' did not include ''tekhelet''.

Royal Purple
Tyrian purple ( grc, πορφύρα ''porphúra''; la, purpura), also known as Phoenician red, Phoenician purple, royal purple, imperial purple, or imperial dye, is a reddish-purple natural dye. The name Tyrian refers to Tyre, Lebanon. It is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name 'Murex'. In ancient times, extracting this dye involved tens of thousands of snails and substantial labor, and as a result, the dye was highly valued. The colored compound is 6,6′-dibromoindigo. History Biological pigments were often difficult to acquire, and the details of their production were kept secret by the manufacturers. Tyrian purple is a pigment made from the mucus of several species of Murex snail. Production of Tyrian purple for use as a fabric dye began as early as 1200 BCE by the Phoenicians, and was continued by the Greeks and Romans until 1453 CE, with the fall of Constantinople.

Sculpture (mollusc)
Sculpture is a feature of many of the shells of mollusks. It is three-dimensional ornamentation on the outer surface of the shell, as distinct from either the basic shape of the shell itself or the pattern of colouration, if any. Sculpture is a feature found in the shells of gastropods, bivalves, and scaphopods. The word "sculpture" is also applied to surface features of the aptychus of ammonites, and to the outer surface of some calcareous opercula of marine gastropods such as some species in the family Trochidae. Sculpture can be concave or convex, incised into the surface or raised from it. Sometimes the sculpture has microscopic detailing. The term "sculpture" refers only to the calcareous outer layer of shell, and does not include the proteinaceous periostracum, which is in some cases textured even when the underlying shell surface is smooth. In many taxa, there is no sculpture on the shell surface at all, apart from the presence of fine growth lines. The sculpture ...

Intertidal
The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of Marine habitat, habitats with various species of Marine life, life, such as seastars, Sea urchin, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or ''shore, seashore'', although those can be defined as a wider region. The well-known area also includes steep rocky Cliff, cliffs, sandy Beach, beaches, Bog, bogs or wetlands (e.g., vast Mudflat, mudflats). The area can be a narrow strip, as in Pacific island, Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in t ...

Haustellum
''Haustellum'' is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails. Like many other genera within the Muricidae, the genus has been redefined several times. Ponder & Vokes (1988) and Vokes (1990) included American and Indo-Pacific species in ''Haustellum'', which differs from ''Murex'' sensu stricto by lacking a labral spine. Petuch (1994) introduced ''Vokesimurex'' for the American long-canalled ''Haustellum'' sensu Vokes (1990), such as '' Murex messorius'' Sowerby, 1841. Houart (1999) transferred 14 Indo-Pacific species and three subspecies of ''Haustellum'' in the genus ''Vokesimurex''. As currently defined, ''Haustellum'' is represented by eight to nine species. Members of ''Haustellum'' generally differ from those of ''Vokesimurex'' in having a globose and low-spired shape, a more rounded aperture, a smooth columella, a less deep anal notch, and no cord spine.
