Mesmerizing lake that remains pink year‑round

Not a Barbie Trend

Western Australia's Lake Hillier’s most distinguishing characteristic is its vivid pink color, an attribute that continues to bewilder scientists and visitors alike. Unlike other pink lakes, which often shift in color or intensity, it maintains its stunning hue consistently.  EnergyButterfly/Creative Commons

In Technicolor

Several factors contribute to Lake Hillier’s remarkable coloration. The primary reason is high salinity levels, a feature it shares with other pink lakes worldwide. The lake’s salinity is even higher than that of the nearby ocean. However, the magic happens when high salt concentrations interact with microorganisms.  Aussie Oc/Creative Commons

The Science Behind It

One of the key players in Lake Hillier’s coloration is a type of microalgae known as Dunaliella salina. This microorganism is exceptional in its ability to thrive in saline environments and is packed with carotenoids, natural pigments that can produce a range of colors. In Lake Hillier, the Dunaliella salina appears to have a preference for the pink spectrum, resulting in the lake’s distinct color.  algaeresearchsupply.com

Salt-loving Microorganisms

Another contributor to Lake Hillier’s rosy appearance is halobacteria, a group of salt-loving microorganisms. These bacteria, like Dunaliella salina, produce pigments that add to the lake’s unique coloration. It is the harmonious interaction of these microorganisms with the lake’s high salinity that maintains the pink allure year-round.  Héctor Mendoza, Biotechnology PhD/Instituto Tecnológico de Canarias
