Leptogorgia festiva is a species of gorgonian sea fan in the family Gorgoniidae. Reef species include plate coral, soft coral, sea fan and sea anemone. The colour of this sea fan is usually light brown to bright red. It is also naturally found in "Paramuricea clavata", or the Red Sea Fan. The skeleton of the Venus sea fan is composed of calcite and a collagen-like substance. The material carried by the ice stream was then deposited in the North Sea fan. The Venus sea fan is white, yellowish, or pale lavender. This sea fan usually grows in areas sheltered from strong current. The sea fan anemone ("Amphianthus dohrnii") seems to live exclusively on sea fans. The Northern sea fan ("Swiftia pallida") is found in the waters off Insh Island. The sea fan anemone ("Amphianthus dohrnii") is often found living on "Eunicella verrucosa". The sea fan "Gorgonia ventalina" can be infected by "Aspergillus sydowii".
