Larnaca Salt Lake Turns Pink

With the onset of summer heat in Cyprus, a unique natural phenomenon has returned: the water in Larnaca Salt Lake has taken on a distinct pink hue. The phenomenon is seasonal in nature and is directly linked to specific climatic changes in the lake's closed ecosystem.

Biological mechanism behind the color change:
Rising air temperatures lead to intense evaporation of the water and, as a result, a rapid increase in the lake's salinity. Such extreme conditions create an ideal environment for the rapid reproduction of specific microorganisms — halophilic microalgae (in particular, Dunaliella salina) and microscopic crustaceans (artemia, or brine shrimp). It is precisely the high concentration of these organisms, which produce protective carotenoid pigments, that colors the remaining water a characteristic pink-red.

Connection with the flamingo population:
Ornithologists note that in the spring the lake looks pink for a completely different, visual reason — because of the presence of thousands of migrating pink flamingos. The birds use the reservoir as a key stopover on their migration route and acquire their famous bright feather color precisely from eating those very microorganisms and crustaceans that now, in the height of summer, are coloring the water itself. With the lake completely drying up in July-August, a dense crust of table salt will form on its surface.
