Lagune e saline di Cagliari -View larger

In the late spring and in summer the waters of the Saline turn taking

on a reddish color. When the salt concentration increases the water

can take on a reddish color. This phenomenon is due to the presence of

microorganisms of red color , the Dunaliella salina and a small

crustacean , Artemia salina able to live in these hypersaline

environments , which gives this variable with the density and color

ranges from pale pink to brick red .

The biomass that blooms in the salt marshes is the first link in the

food chain of these environments they depend on the brine shrimp and

flamingos of which you can see a large group in the photo .

Very interesting! The redish pond contrasted strongly with the blue water outside and it sure brings the point home of how the flamingoes got their pink color.  TFS!

Amazing colors and POV.  Thanks for sharing. 

both the info and the shot are very interesting!

Interesting photo and explanation.  The hot water geysers at Yellowstone also have bacteria that turn their habitat red.

Bellissima!!! Ciao, Maurizio.

Grande !
