This splendid study of the Pimplet Anemone was taken near the wreck of the Colussus, off Samson Island, Isle of Scillies
 

Reports:

30 March 2002
Lancing beach  was home to five species of sea anemones including large Dahlia Anemones and frequent Snakelocks Anemones, enough to identify this location as the most easterly regular location of this sea anemone on the northern English Channel. 
The Pimplet Anemone was also discovered, another anemone species that has never been recorded this far east before.
