Is the Red Sea really red?
No, the Red Sea is not always red, but sometimes it appears to be. The Red Sea got its name from a phenomenon caused by a type of algae called Trichodesmium Erythraeum, which is found in the sea. When these algae blooms die off the blue-green color of sea appears to change to reddish-brown color. the Hebrew name is always translated “Red Sea,” which was the name given to it by the Greeks. The origin of this name (Red Sea) is uncertain. Some think it is derived from the red colour of the mountains on the western shore; others from the red coral found in the sea, or the red appearance sometimes given to the water by certain zoophytes floating in it.
