The bizarre colour is caused by high levels of salt - with some areas containing up to 40% of the condiment.

Michael Danson, an expert in extremophile bacteria from Bath University, said: “The strawberry colour is produced by salt-loving organism Dunaliella salina.

“They produce a red pigment that absorbs and uses the energy of sunlight to create more energy, turning the water pink.

“Lakes like Retba and the Dead Sea, which have high salt concentrations, were once thought to be incompatible with life - hence the names. But they are very much alive.”

Photographer, Anna Henly, used a fisheye lens to make the enormous predator look diminutive on the top of the world. 

This poignant image, entitled Ice Matters was taken from a boat in Svalbard, and has won Anna the Veolia Environment Wildlife Photographer of the Year competition, in the category of The World in Our Hands.

Winning photos will be on exhibit at the Natural History Museum in London until March 3, 2013.

Aurora Borealis, Svalbard

Photograph by Max Edin

I was visiting Longyearbyen, Svalbard, way up over the Arctic Circle, when I decided one clear night to go out and photograph the stars. After I made it to the location I’d chosen and had set up my exposure, the most beautiful aurora borealis show I’ve ever witnessed happened right overhead. The full moon at the time helped brighten up the foreground, creating this image.
