A polychaete (Scalibregma inflatum)

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

Summary

Description

A segmented worm with between 30 and 60 subdivided segments and a small head with two anterior lateral projections forming a T shape. The body is 5-10 cm long and wrinkled in appearance. Scalibregma inflatum is swollen anteriorly and then becomes slender towards the rear. Purplish red with yellow blotches it has four pairs of branching gills present on the second to fifth segments.

Recorded distribution in Britain and Ireland

Widespread around the UK, few records for Ireland.

Global distribution

From the Arctic all around Britain to the Atlantic coast of Europe.

Habitat

Found around low water mark and in the shallow sublittoral, buried deep in sand or mud.

Identifying features

  • Body 5-10 cm long.
  • Swollen at the front, becoming slender towards the rear.
  • The head has two anterior lateral projections forming a T shape.
  • Four pairs of branching gills present on the second to fifth segments.
  • From about segment 16, finger-like dorsal and ventral cirri present.
  • The posterior end bears four or five thread-like cirri.
  • Purplish red with yellow blotches.

Additional information

Scalibregmatidae (sometimes called maggot worms) are not routinely encountered, although they can occur in huge numbers in shallow waters in northern Europe. More often, they occur in muddy sediments at more than 1000 m depth. They are active burrowers and feed on detritus in sediment and never form tubes.
