Murex trunculus

When the lipid composition of the ganglion in four species of gastropod (Helix pomatia, Lymnaea stagnate, Murex trunculus, and M. brandaris the last two species inhabit the sea) was investigated by biochemical and histochemical methods, the glycosphingolipids were found to be present mainly in the form of sulfatides, whereas gangliosides are absent.60...

Three Mediterranean species of marine snail which dwell in the same seawater adjacent to a nickel smelting plant accumulate markedly different levels of metals (Nott and Nicolaidou 1989). The highest levels occurred in the sediment feeder Cerithium vul-gatum and the lowest levels in the predator Murex trunculus, which preys on C. vulga-tum. It has been established that metals in...

The color was, and still is, prepared from several mollusks including Murex brandaris, Murex trunculus and Purpura haemostoma, found on the shores of the Mediterranean and the Atlantic coast as far as the British Isles [31, 32]. The method of extraction and preparation of the colorant was one of the most complex, time-consuming, and labor-intensive activities carried out by the ancients. The reasons are (1) it purportedly takes 10,0(X) shellfish to produce one gram of the pure colorant (see Fig. 4.7) (2) the colorant itself is not actually present in the living animal but its precursor must be excised from the snail s hypobranchial gland (3) the colorant must be produced by a complex chemical process involving enzymatic hydrolysis of the dye precursors and subsequent photochemical oxidation.
