Peppery furrow shell (Scrobicularia plana)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

This bivalve has a thin, rounded and flattened shell and grows up to 6.5 cm in length. Internal features for identification are the hinge of the valves (the right valve has two teeth and the left valve one tooth) and the broad and almost circular pallial sinus. Externally, the shell is sculptured with fine concentric lines, the outer surface white, pale grey or yellow and the inner surface is white.

Recorded distribution in Britain and Ireland

Common to all British and Irish shores and often locally abundant.

Habitat

The peppery furrow shell is found in estuarine and intertidal conditions and is able to tolerate low salinities in thick mud or muddy sand. It burrows up to 20 cm deep in sediments and can be identified when buried by the characteristic star-shaped markings made at the surface by its inhalant siphon.

Identifying features

  • Thin, rounded, flattened shell.
  • Up to 6.5 cm long.
  • Outer surface white, pale grey or yellow.
  • Inner surface white.

Additional information

Feeds by extending a siphon above the sediment when the tide is in. The siphon is often clipped by fish, crabs and birds, however lost tissue is regenerated within four or five days.
