Recorded distribution in Britain and IrelandAulactinia verrucosa is a southern species reaching its northern limit in the British Isles where it is most common on south and west shores. Present on all Irish coasts. Recorded at a few locations in south-west Scotland and Shetland.
Global distributionPresent in south-west Europe and the Mediterranean.
HabitatFound on the shore in localities exposed to strong wave action but also in sheltered places. Typically found in crevices in shallow water and in rock pools among Corallina. Also found attached to the bedrock beneath the layer of sand or gravel which often accumulates on the bottom of pools.
- Verrucae prominent and arranged in up to 48 vertical rows.
- No acrorhagi present, but verrucae extend on to the parapet.
Additional informationAulactinia verrucosa closes tightly when disturbed assuming a hemispherical shape resembling the denuded test of Echinus. It is similar to Anthopleura rubripunctata, which is often larger (up to 70 mm tall) and is covered with verrucae that are often red.
