For the longest time, the Pink Lake in Goldsfields-Esperance region in Western Australia was a mystery.

One might mistake the beautiful pink color to be man-made, but the unusual color is actually a natural phenomenon.This salt lake is not always pink, the change in color is a result of a certain green algae or high concentration of brine prawn.

Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions are provided; the alga begins to accumulate the red pigment beta carotene. The pink halobacteria grow in the salt crust at the bottom of the lake and the color of the lake is a result of the balance between, D. salina and H. cutirubrum.
