Description

The size of the shell varies between 10 mm and 35 mm. The very thick and solid imperforate shell is subperforate in the young. It has a globose-conic shape. It is dull grayish, densely marked all over with very numerous fine flexuous or zigzag braided purplish-black lines. The spire is conic. The 6 to 7 whorls are convex. The apex is usually eroded and orange-colored. The body whorl is flattened around the superior portion. The base of the shell is eroded in front of the aperture. The aperture is oblique. The columella is short, obtusely subdentate near the base, spreading at the insertion into a heavy callous, which covers the umbilicus.

Phorcus lineatus Phorcus lineatus DORIS

This species is similar to Phorcus turbinatus in form, but usually has the outlines of the spire more convex. The columella projection or tooth is nearer the base than in the Phorcus turbinatus, and the diverse color patterns will serve to further distinguish the two species.

This species occurs in the following locations:

  • European waters (ERMS scope)
  • Portuguese Exclusive Economic Zone
  • Spanish Exclusive Economic Zone
  • United Kingdom Exclusive Economic Zone
  • Wimereux
