Sea lemon (Doris pseudoargus)

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

Summary

Description

A large sea slug up to 12 cm long. The top side of the slug is covered in small wart like bumps (tubercles). It has a ring of eight or nine upright feathery gills close to the posterior end, which are quickly retracted when a disturbance is sensed. The colouration of the sea slug is blotchy and variable and can be yellow, green, brown or pink. There is another variety (var. flammea) that is bright red all over.

Recorded distribution in Britain and Ireland

Found all around the British Isles.

Identifying features

  • Oval body up to 12 cm long.
  • Mottled in colour, usually yellow but can be green, brown or pink.
  • Top side covered in small wart like bumps.
  • Ring of 8-9 feathery upright (tripinnate) gills near posterior end.

Additional information

The sea slug Geitodoris planata can be distinguished from Doris psuedoargus as it has star-shaped spots on its back (dorsum) and brown specks on the underside of the mantle. The sea lemon feeds mainly on sponges, especially the breadcrumb sponge (Halichondria panicea). Once used as fish bait in Shetland (Thompson & Brown, 1976).
