SEA-WORMS AND SEA-ANEMONES 



FIG. 6. British Sea- Anemones. 



a, Sagartia bellis, the daisy anemone, viewed from above when fully 



expanded. 



b, Bunodes crassicornis, half expanded ; side view. 



c, Anthea cereus. The tentacles are pale apple-green in colour, tipped with 



mauve, and cannot be completely retracted. 



d, Actinia mesembryanthemum. The disk of tentacles is completely retracted. 



This is the commonest sea-anemone on our South Coast, and is usually 

 maroon colour, but often is spotted like a strawberry.
