The name 'Red Sea' is rumoured to come from the seasonal blooms of a red coloured algae that appears near the surface at certain times in the year. But despite its name, the waters are an amazing blue water destination boasting comfortable water temperatures throughout the year, superb visibility and great dive conditions year round. The Red Sea is considered to be one of the 7 Wonders of the underwater world, harbouring more than 1,000 species of invertebrates and over 200 species of soft and hard coral. This forms the basis of a marine eco-system which includes 1,100 species of fish, of which just under 20% are endemic to the Red Sea, i.e. these fish species can only been found here. The high level of endemism here is one of the main factors that makes Egypt scuba diving so interesting.
