|CNIDARIA : ACTINIARIA : Sagartiidae||SEA ANEMONES AND HYDROIDS|
Description: The base of this sea anemone is closely adherent. The column is similar to that in Sagartia species, but flaring out, trumpet-shaped, to the wide disc. There are suckers on the column usually with gravel stuck to them. The tentacles are short and very numerous - more than 1000 in large specimens. The diameter of the disc may reach 100mm or more. The column is typically grey-brown, darker, almost purplish above; sometimes yellowish, pink, or reddish. The disc is often patterned and usually minutely flecked with white. Many colour varieties occur - brown, blue-grey, yellowish, typically variegated with purple, black, white, scarlet, etc.; a plain brown variety is common in some regions. Reproduces viviparously, often producing numerous young.
Habitat: Found on the shore in pools and gullies, typically with the base inserted into a deep crevice; or buried in mud or sand, attached to some buried object. Also occurs sublittorally on sand scoured rocks, often partly buried in sand, to at least 50m.
Distribution: A common species on the south and west coasts of the British Isles, all around southwest Europe and in the Mediterranean.
Similar Species: Sagartia troglodytes, Cereus pedunculatus and Sagartia elegans all possess suckers on the column. In the first two of these species the suckers usually have gravel stuck to them.
