Different photoreceptors(视细胞) in the eyes can affect how we see the world around us. Animals including bees and some birds can see ultraviolet light(紫外线)that human eyes cannot see. By reconstructing the colours that we know animals can see, scientists can learn more about how they commu...

Ultraviolet colour vision and ornamentation in bluethroats Many birds see in the ultraviolet (300-400 nm), but there is limited evidence for colour communication (signalling by spectral shape independently of brigh...

While humans have three color receptors (which, in combination, result in all the visible shades humans see), mantis shrimp have 12 to 16—they can even see ultraviolet, polarized, and infrared light. Despite the fact that they have so many different receptors, their visual system works in ...
They have eight pairs of eyes. They can see more colors than us. They can see ultraviolet light (紫外线). So they see things more clearly than we do. They can move one eye in different directions (方向) while keeping the other eye stop moving. It is to see their enemies (敌人) bet...
