Frequently Asked Questions
No, it is an extremely rare, specialist term known mostly to scientists, historians, and shell enthusiasts.
No. It refers specifically to snails of the family Muricidae, many of which are spiny and were historically used for dye. Using it for any shell is incorrect.
Several species of murex were the source of Tyrian purple, an extraordinarily valuable and colourfast dye in antiquity, associated with royalty and high status.
Yes, the standard plural is 'murexes' or, in scientific contexts, the Latin plural 'murices' (/ˈmjʊərɪsiːz/).
