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

Summary

Description

The disc and the tentacles are orange or light brown. Most specimens have a delicate pattern of dark brown and white overlying this but it may be absent. Irregular streaks of opaque white may occur on the disc and tentacles. The tentacles are moderate in length and arranged in multiples of 6, in 5 cycles up to 96. The diameter of the base is up to 4 cm and the height is up to 5 cm. The base is broad and adherent. The major part of the column, directly above the base, is orange, red, brown or buff. The column above this is dark brown often purplish and with a white line encircling the upper-most limit.

Recorded distribution in Britain and Ireland

Recorded from the English Channel, western and northern coasts of Ireland, western Scotland and the Shetland Isles.

Global distribution

Recorded from the Mediterranean, around south western Europe to northern France.

Habitat

Occurs usually attached to organic substrata, such as shells and worm tubes but can also be found attached to stones or rocks. A sublittoral species which occurs down to 100 m.
