Great Barrier Reef

The Great Barrier Reef, in Queensland, Australia, is the largest venue of coral reefs and consists of about 400 kinds of corals, 3,000 reefs, and some 900 islands. Being the only living organism that can be seen from the world's orbit explains why the Great Barrier Reef was chosen as a World Heritage Site and one of CNN's "Seven Natural Wonders of the World."

But more than being visible from the outer space, the Great Barrier provides habitat for a lot of marine life, many of which are already endangered. There are almost 30 kinds of dolphins, porpoises and whales that are scattered beneath the reefs that include Humpback Whale and Dwarf Minke Whale. Sea turtles and dugongs (sea cows) also make up the wide demography of sea creatures. Mollusks of over 5,000 species are recorded along with 200 of bird species and sea snakes of roughly 17 species.

Naturally formed and beautified, the Great Barrier Reef has been in the list of the greatest underwater sights on Earth. Tourists will definitely bounce on and off the place, rediscovering the world underwater; eventually, after experiencing all the wonders that the Great Barrier Reef has to offer, you will regain a renewed respect for Mother Nature and her works of art.
