Brown Algae; Phaeophyceae

Brown algae, generally known as the seaweeds, are not true plants at all. Although they do photo-synthesize, their body structure is much more primitive. This class includes many commonly encountered marine algae, including the diving underwater photographers favourite host – Sargasso Seaweed.
