Did you know that…? “…the Red Sea is not red but an intense blue-green. Its name derives from the blooming cyanobacterium, Trichodesmium erythraeum, also called blue-green algae. It sometimes reproduces in enormous numbers, forming a mile-wide slimy layer on the surface of the sea. After a couple of days, the algae die and stain the sea a reddish brown.”
