Lake Hillier is a body of water located on Middle Island, Recherche Archipelago, Western Australia. What makes this lake unique?
1. It’s pink in colour! No really. Lake Hillier is a lake whose waters are pink in colour.
2. No. The lake waters have not been mixed with a pink paint. The lake is actually a salt lake. And it gets its pink colour from organisms in the lake which produce a pink-coloured dye or from red halophilic bacteria found in its salt crust!
3. What are halophilic bacteria? Are they a special kind of bacteria? Well, sort of. Certain bacteria are capable of living in extreme conditions – in this case, an excessively salty environment. Halohilic bacteria need water saturated with salt to survive.
