Red alga

A small multicellular marine red alga shown as a seaweed-like thallus arising from a small basal holdfast or attached-looking base. The body has delicate branching fronds that may be flattened, ribbon-like, feathery, lobed, sheetlike, slightly cylindrical, or filamentous, with smooth to gently wavy edges and a soft, flexible, slightly fleshy organic appearance. Color ranges from deep red and crimson to reddish purple, burgundy, or maroon, often with a semi-translucent quality. It lacks obvious flowers, seeds, true leaves, or true roots, giving a simple plantlike marine silhouette.
