Identifying features

  • The junction between basal disc and column (the limbus) is not sharply defined.
  • Numerous minute, adhesive spots (or rugae) present on lower half of column by which anemone may attach in preference to base.
  • Tiny perforations (cinclides) fairly prominent when column well extended.
  • Thread-like acontia emitted reluctantly but often visible through translucent column wall.
