Summary

Description

A large whelk up to 10 cm high and 6 cm wide. The shell has 7-8 whorls with spiral ridges. The shell is yellowish brown with irregular light and dark spiral areas. The aperture is broadly oval tapering to a point with a short wide siphonal canal leading from the base of aperture.

Recorded distribution in Britain and Ireland

Common off all British coasts.

Global distribution

Distributed from Iceland and Norway to Bay of Biscay and throughout the North Atlantic.

Habitat

Occasionally intertidal but mainly subtidal down to 1200 m. Found on muddy sand, gravel and also rock. Sometimes present in brackish waters.

Depth range

From low water to 1200m

Identifying features

  • Stout shell up to 10 cm in height.
  • 7-8 whorls last whorl 70% of height.
  • Broadly oval aperture.

Additional information

There is a significant fishery, which uses traps, for common whelks. The majority of the whelks are exported to the far east. Masses of lentil shaped eggs are often found attached to subtidal rocks, stones or shells. Empty egg masses, known as 'sea wash balls', are often found on the strandline and are sometimes mistaken for sponges. Buccinum undatum may be confused with the red whelk Neptunea antiqua. Neptunea antiqua does not have the coarse ribbing of Buccinum undatum and is not edible.
