One of the true wonders of the world, and also the world's biggest structure that can be seen from outer space, the beauty of the Great Barrier Reef cannot be imagined unless experienced personally. Made of 2,600 different reefs, it is around 2,000 km long. It starts just south of the Tropic of Capricorn.
Dating back to around 18 million years ago, this place was declared a World Heritage Area in 1981. This was primarily due to the spectacular beauty of the place and even because it supports a wide diversity of life, which includes many vulnerable or even endangered species.
The name of this reef was derived because it is an outer reef that reaches a depth of about 60 m. It is situated along the Australian continental shelf with the channel between the coastlines, and is composed of billions of coral polyps. These tiny organisms help in supporting the entire system of the reef.
Various factors, such as the temperature of the water, the salinity, and even the depth of the water, count in their survival. Today, there are nearly 400 types of coral in this reef. This area is also rife with plenty of species of fish and other sea creatures.
The Great Barrier Reef supports a large diversity of life. The islands are also home to sea birds and turtles. It also records a wide range of whales, dolphins, and porpoises; sea turtles are found in around 6 species in this area.
With the linking of so many living organisms to this reef, it becomes mandatory that the conditions be maintained by man for the corals to survive. With such a vivid sea life it is no wonder that the colors of all the corals and life found there is beautiful and breathtaking, from the soft pinks and deep greens to bright blues and silver.
