Lake Thetis is one of only a few places in the world with living marine stromatolites. These exhibit unusual columnar branching having narrow, closely spaced and almost parallel columns. A diverse array of benthic microbial communities, such as algal mats, also inhabit various layers of the lake.

The lake water is alkaline and nutrient poor but provides an ideal environment for bottom dwelling microbial communities. The lake contains some small fish, amphiods and a few crustacean species adapted to living in highly saline environments. For more information on this unique site, refer to the images this page.
