They see the human eye can not see!

An international science team, says rengeyiklerinin human eye can not detect the ultraviolet rays.

Rengeyiklerinin

living in the Arctic, unlike people, was his reaction to ultraviolet light.

Experts rengeyiklerinin polar environment, this ability can locate food more easily through the twilight of the long winter months and can see the remote thinks düşmanarını.

Ultraviolet rays, the wavelength range of light detected by the human eye, except for a short stay is located.

The researchers measured the response of the retina, giving anesthesia uyutulmuş rengeyiklerinin retinasına ultraviolet radiation.

The experiment, the light receptors in the retina of deer detected by ultraviolet rays existed.

Experts rengeyiklerinin the main food sources deer moss on the trees looked black and you think, because these so-called lichen algae species absorbs ultraviolet rays.

Likewise, it appears that wolves

rengeyiklerine people is expected to appear darker. Because the wolf with feathers can absorb the ultraviolet rays.

Snow white snow-covered environment, the objects appear to distinguish it from black people than the much easier to rengeyikleri.

Trace of urine in the snow

rengeyiğinin algıyabildiği easier with ultraviolet light, so deer around an enemy-thinking that maybe some other life-is said to be moving.

Researchers rengeyiklerinden after a similar attempt on the test seals. Ultraviolet rays is assumed to have the capacity to see the seals.

Professor Lars Chittka of the University of London Queen Mary

, bees can see ultraviolet rays also said,''In fact, humans and some mammals, the creatures have lost the ability to detect ultraviolet rays, may constitute an exceptional case.''He says.
