Barnacles (top center and right middle section): The volcanic, conical shells that appear in clusters belong to the family of barnacles (Perforatus perforatus or Balanus)

Colonial shells (top left and bottom left): Parts of large shells (Ostrea edulis), which are fully covered by calcareous tubes (serpulid worm tubes) and small bases of barnacles

Bivalve shell (bottom right): Classic ribbed bivalve shell (Cardiidae or Pectinidae) with small attachments on its surface

Wood bark (middle right): The back side of the small cluster of barnacles reveals that they were attached to a piece of hard wood bark or marine plant

Calcareous tubes (bottom left): Entirely dense, solid mesh of tubes from marine worms (serpulid tubes)

Smooth bivalve (bottom right): The growth lines and the point where the soft tissue of the animal was attached are visible

Mother-of-pearl (top middle): The inner side of the cluster of barnacles reveals an impressive, iridescent (pearly) purple and blue hue, characteristic of their attachment base
