Nov. 11 (UPI) --It's easy to get lost in a coral reef. To locate friends and family, anemonefish evolved the ability to see ultraviolet light. To better understand how anemonefish navigate the bright, ...

Researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal ...

Two species of damselfish may look identical -- not to mention drab -- to the human eye. But that's because, in comparison to the fish, all of us are essentially colorblind. A new study reveals that ...

First, some basics: Vision depends on light, which comes in a spectrum of wavelengths, ranging from very long to very short. Vertebrate eyes have two kinds of light receptors in the retina at the back ...

ultraviolet light. But not all avian eyes are created equal, according to new research. Apparently, birds with smaller eyes are better able to perceive the UV spectrum. Many animals can see ...

We know that there's a whole spectrum of different wavelengths of light beyond the puny band of visible light we humans can see. And we knew that some animals, like certain species of fish and birds, ...

While we might use eye color and hairstyle to tell people apart, some fish species rely on ultraviolet light patterns of faces to distinguish one species from another, a new study finds. Scientists ...
