Description The southern populations of this species, in Portugal and Morocco, are quite different from those present on the coasts of NW Europe, usually with a high-conical shape and more red component in the colour pattern. They can be distinguished readily from Jujubinus spp. by the presence of an umbilicus.Author Gofas, SergeJPG file - 51.24 kB - 953 x 583 pixelsadded on 2013-02-141 457 viewsFrom reference Gofas, S.; Moreno, D.; Salas, C.
