ALLIGATOR TURNS BLUE

“This alligator could be excused for being snappy – she is clearly feeling blue. The large gator looks a stunning shade of blue as the bright morning sky reflects off her wet back. She appeared to change from her usual dark brown to black, grey and blue over the space of just a few minutes as the sun rose over the lake at 7am. But unlike a chameleon, the change of colour was not a conscious decision. It was purely down to the sky reflecting off her shiny scales. Biology professor Louis Guillette, 55, took the picture on a lake next to his home in Gainesville, Florida, United States.” LINK
