SINAI AND THE RED SEA COAST

2 2 7

Coral Reefs of the Red Sea

Coral reefs are one of the richest ecosystems on earth. X Coral is made up of colonies i ^ of tiny animals called polyps % that need precise environmental \ conditions to grow. There are colourful racoon two types of coral: hard corals, butterfly fish which form hard outer skeletons for themselves, and soft corals, that do not. Most reefs are built over thousands of years from the accumulated skeletons of dead hard corals. In places, the Red Sea reefs form sheer walls covered with exotically shaped corals of pastel pink,

yellow and red. Scuba diving in the Red Sea is the highlight of many visitors' holidays and the area is well served for dive centres (seepp316-21). However, if using an aqualung does not appeal, the reefs create shallow lagoons, perfect for exploring with a snorkel. These beautiful, calm lagoons serve as nurseries for schools of smaller fish. A word of caution: although the reefs seem robust, they are an extremely fragile environment and swimmers should look but not touch.
