Red Algae (Division Rhodophyta)
Members of this phylum are also characteristically marine. A few forms, including Batrachospermum and Lemanea, inhabit fresh water.
They are mainly found in streams. All red algae are multicellular and exhibit considerable variety of form and coloration. It should be emphasized, however, that red algae are not always red, many are as dark a color as black. The red algae pigments include chlorophyll A and chlorophyll D, xanthophyll, carotene, phycocyanin, and phycoerythrin.
