Metridium senile (Plumose anemone)
Metridium dianthus, common name the plumose anemone or frilled anemone, is a species of sea anemone in the family Metridiidae. It is found in the seas off northwest Europe and the east and west coasts of North America. This anemone is perhaps better known by its synonym, Metridium senile; but that name is now considered invalid.
