The freshwater red alga Compsopogon coeruleus (Balbis) Montague is capable of growing and reproducing in salinities up to 35 ppt. Increased accumulation of floridoside (D‐galactopyranosyl glycerol) parallels increase in salinity. Compsopogon phycobilisomes contain an unusual B‐phycoerythrin completely lacking in phycourobilin chromophores, but with a pigmented γ subunit. The α, β, and γ subunits of this phycoerythrin all carry phycoerythrobilins. These results suggest that C. coeruleus is secondarily adapted to freshwater from marine habitats.
