Giant Cladophora Cladophora mirabilis
A giant among Cladophora species, C. mirabilis grows to 40 in (1 m) long. It is bluish green and filamentous, with many straggly side-branches. Giant Cladophora is made up of strings of cells, but individual cells in the main axis may be in (12 mm) long. The plant attaches using a disk made of interwoven extensions of its basal cell, and often has red algae growing on it. It has a very limited distribution in South Africa, but other species of Cladophora are common worldwide.
