Frequently, on the banks of Monaco, one can see white ascidians: Ciona Intestinalis. The Astrospecten is a star of the sea. The sea urchin Echinus Microtuberculatus moves with feet in the shape of tubes. A world where one fights for a bit of seaweed. Flowers?, No. Miniscule worms called serpules, that live in calcareous tubes. Other worms of large size spread magnificent plumes. The naturalists name them Spirographis Spallanzanil. The sea anemones… named just with the title of "Living Flowers."
