The Great Barrier Reef is the world’s largest coral reef system composed of over 2900 individual reefs and 900 islands stretching for over 1400 miles over an area of 133,000 sq. miles. The reef is located in the Coral Sea off the coast Queensland, Australia.
The Great Barrier Reef is the world’s largest structure made by living organisms and can be seen from outer space. It has been selected as a World Heritage Site and is labeled at one of the seven natural wonders of the world.
The Great Barrier Reef supports a great diversity of life on the sea floor, including some species that are only found in this reef system. The wildlife that lives on the ocean floor in the Great Barrier Reef are:
• 15 species of sea grass
• 5000 species of mollusk
• 330 species of ascidians
• 400 species of bryozoans
• 400 species of coral including both hard coral and soft coral.
While there are an amazing amount of wildlife that lives on the ocean floor of Great Barrier Reef, the focus of this post is on the coral that make up the reef. Obviously I can only feature a small number of the coral that are the structure of the reef because I was only able to spend one day snorkeling and diving on the reef. The coral that I was able to get nice photos of while diving and snorkeling are shown below:
