Extreme Animal Portraits: Wildlife Photographer Of The Year Winners

Winner, Animal Portraits — An alligator is seen at Myakka River State Park in Sarasota, Fla. Like cats, alligators have a tapetum lucidum at the back of each eye — a structure that reflects light back into the photoreceptor cells to make the most of low light. When light shines into alligators' eyes, the pupils appear to glow red. Picture show here.
