Shark Bay, Australia
The Shark Bay site in Australia was inscribed on the World Heritage List in 1991. The site is home to the world's richest and largest sea-grass beds; five species of endangered marine mammals, including dugongs (Dugong dugon), which feed on the grass; and stromatolites, dome-shaped structures created by cyanobacteria, one of the oldest forms of life on earth.
Today, over 40 World Heritage sites are listed for their marine values.
