Red algae owe their color to the pigment phycoerythrin, which reflects red light and absorbs blue light. Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments let red algae photosynthesize at somewhat greater depths than most other algae. Some have very little phycoerythrin and look green or bluish. In Asia they are important sources of food such as nori, which has been cultivated in Japan for more than 300 years. The coralline algae secrete a hard carbonate shell and have helped build tropical reefs for millions of years, contributing more to some Pacific atolls than corals did.
