Two species common in the Mediterranean Sea, Murex trunculus and Murex brandaris, were the source of a costly purple dye used to color cloth in Bible times.
Divas no Vidusjūrā sastopamajām purpurgliemežu sugām — Murex trunculus un Murex brandaris — tika izmantotas vērtīgā purpura ieguvei, ar kuru Bībeles laikos tika krāsoti audumi. ( Esteres 8: 15; Lūkas 16: 19.)
