Parasitic zoanthid anemones cover, encrust and overwhelm a golden gorgonian. The gorgonian on the left has been completely parasitized by zoanthid anemones, while the gorgonian to the right remains free of zoanthids (for now). A garibaldi swims below the two sea fans. The golden gorgonian is a filter-feeding temperate colonial species that lives on the rocky bottom at depths between 50 to 200 feet deep. Each individual polyp is a distinct animal, together they secrete calcium that forms the structure of the colony. Gorgonians are oriented at right angles to prevailing water currents to capture plankton drifting by.

The Kelp Forest and Rocky Reef of San Clemente Island. Giant kelp grows rapidly, up to 2' per day, from the rocky reef on the ocean bottom to which it is anchored, toward the ocean surface where it spreads to form a thick canopy. Myriad species of fishes, mammals and invertebrates form a rich community in the kelp forest. Lush forests of kelp are found throughout California's Southern Channel Islands.

The leafy seadragon (Phycodurus eques) is found on the southern and western coasts of Australia. Its extravagent appendages serve only for camoflage, since it has a nearly-invisible dorsal fin that propels it slowly through the water. The leafy sea dragon is the marine emblem of South Australia.
