Snorkeling south of Jeddah
Yesterday I had the wonderful experience of accompanying some Saudi friends on a snorkeling adventure into the Red Sea, about 90 kilometers south of Jeddah, Saudi Arabia. My previous experience of exploring coral reefs had been in snorkeling around Virgin Gorda in the British Virgin Islands and scuba diving off the Gulf coasts of Belize and Mexico. However, what I witnessed beneath the waters of the Red Sea was equally incredible.
The Red Sea coral reefs are among the most beautiful of all the world’s marine habitats. This vast inlet of the Indian Ocean provides ideal conditions for corals and other countless forms of aquatic life. There are about 200 species of “stony corals” along the coast.
Most corals are reef builders. Each of these sea polyps builds a skeleton and the animal sits in a calcareous cup that it has secreted. The polyps are connected to each other by an extension of the body above the level of the skeleton. Thus the colony sits on the surface of the skeleton, feeding on algae and particles of food drifting along in the water.
The Red Sea coral reefs form an ecological environment in which creatures can take refuge from predators. Crustaceans, eels, starfish, turtles and thousands of varieties of fish–all benefit from this beautiful ecosystem. Fish that are found in these reefs include some very colorful species. One will find brilliant orange coral groupers, enormous gorgonian fan fish, moray eels and elaborate lionfish and majestic, swooping giant manta rays. We even saw “Nemo” who was made famous by the film “Saving Nemo.”
In deeper waters there are such species as hammerhead sharks and barracudas and various varieties of jellyfishes which look attractive but can deliver their unpleasant stings.
Jacques Cousteau and these coral reefs
I am told that Jacques Cousteau chose this celebrated Red Sea reef system to first introduce the world to undersea life, and by the same token it is not by chance that so many people become diving and snorkeling fanatics during their visits to Saudi Arabia.
The exceptional richness of marine life in the Red Sea is due to an unusual combination of environmental factors. First, the Red Sea is comparatively sheltered and calm: its currents are gentle and regular, its tides almost non-existent, and its temperature warm and steady. While its waters run quite deep, they are warmed by volcanic heat emanating from the sea bed. The result of all these factors is an environment ideally suited to the complex and delicate ecosystem of coral reefs.
Considering all the world’s most celebrated reef systems, these of the Red Sea stand out for their unusual wealth of specific kinds of marine life–most notably, coral itself. The sheer abundance of corals, many of exceptional size and color, makes diving and snorkeling in the Red Sea an experience of almost magical intensity.
Today, one-third of shallow water, reef-building species are threatened with extinction, making them one of the most endangered animal groups on the planet. These reefs are suffering from many environmental impacts, including the effects of climate change, pollution, over-fishing of animals that live on the reefs, and removal of the reefs for use as home décor objects and curio and aquarium trade.
