A view of an underwater forest of giant kelp, Macrocystis pyrifera
A view of an underwater forest of giant kelp. 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 through California's Southern Channel Islands. San Clemente Island, USA
