Summary

Description

This is a short and squat anemone with a smooth column. The anemone has up to 100 tentacles, each ending in a small knob. Corynactis viridis is brilliantly coloured and can be green, pink, red, orange or white in various combinations. Usually the disc, tentacles and tentacle tips are contrasting colours.

Recorded distribution in Britain and Ireland

Corynactis viridis reaches its northern limit in Shetland. It is found around the south and west coasts of Britain and all around Ireland.

Global distribution

Recorded around the British Isles, south-west Europe and into the Mediterranean.

Habitat

Corynactis viridis occurs from the lower shore and into the subtidal to about 50 m (sometimes to 80 m) on rocks, in caves and beneath overhangs where it is shaded from light. The anemone is often found in dense aggregations especially on vertical rock faces.
