Located off the coast of Australia, Great Barrier Reef presents an amazing underwater scenery. Very colorful and a breeding place of the beautiful coral reef and also home to many marine animals such as the saltwater crocodile, Sea Dragon, and more than 125 types of sharks.
The Great Barrier Reef in Australia is the only living collective that can be seen from the Earth’s orbit. It is composed of some 3,000 coral reefs and 600 islands that make up to at least 1,250 miles. Global warming is certainly threatening this marvel by causing coral bleaching that may mean functional extinction of this system by 2050.
