Brown algae were assumed to have arisen from the fusion of photosynthetically inactive colourless cells with a unicellular red alga

with a red alga
and thus refuted a widespread theory among experts.
Hata and Kato have been analyzing the Stegastes nigricans damselfish's patches of a Polysiphonia, which is categorized as a red alga

Since the phosphatic clay performed so well against the red tide alga
and was literally free for anyone willing to cart it away, Sengco and his Woods Hole colleagues are working out the best ways to use it in trials in Florida and the Pacific Northwest.
Both are prime nutrients for the red-tide alga
