The Wooramel Seagrass Bank in Shark Bay is the world’s largest seagrass bed. It is 1030 sq km in area and has taken 5,000 years to develop.
Shark Bay is the most abundant and diverse microbial ecosystem in the world. The Stromatilies are microscopic organisms or “cyanobacteria” that concentrate and recycle nutrients which combine with sedimentary grains to form towers of rock-like materials. These “living fossils” are two to three million years old.
