About this place
Like the famous stromatolites of Hamelin Pool in Shark Bay, the rock-like structures on the edge of Lake Thetis are built by micro-organisms too small for the human eye to see.
Within the structures are living communities of diverse inhabitants with population densities of 3000 per square metre! The stromatolite-building micro-organisms of Lake Thetis resemble the earliest forms of life on Earth. The discovery of modern examples helped scientists to understand the significance of micro-organisms in the environment and unravel the long history of life on Earth.
Today, living examples of these once completely dominant organisms are restricted to only a few places.
