CNIDARIA : ACTINIARIA : SagartiidaeSEA ANEMONES AND HYDROIDS

Sagartia troglodytes (Price in Johnston, 1847)


Description: This sea anemone has a wide and moderately adherent base. The column is similar to Sagartia elegans but suckers less conspicuous, acontia not very readily emitted. The tentacles are moderate in length, arranged in multiples of six, up to 200. Colour is extremely variable: column dull-greenish, whitish, buff, etc. usually with pale stripes at base. Disc with a pattern or plain, tentacles banded or plain. Occurs in most colours or combinations of these. Large form (decorata) typically up to 50mm across base, 100mm tall.

Habitat: On the shore or shallow sublittoral. Attaches to rocks, etc., but more commonly occurs buried in mud, sand or gravel, attached to a buried stone or shell. Occasional in brackish water.

Distribution: Common on all coasts of the British Isles except the English Channel, where it is infrequent. Occurs on all European coasts, including the Mediterranean.

Similar Species: Distinguished from Cereus pedunculatus by smaller number of tentacles and narrower disc; see also Sagartia elegans for differences between these species.
