Heterochromia iridum

Whether you heard about such phenomenon as heterochromia? Isn't present? And if to ask — whether you met animals or people with different eyes, then surely there will be witnesses of the similar phenomenon. And so, distinction of color of an iris of the eye of eyes of one and other eye or some sections of an eye is also this heterochromia.

The result of "different eyes" is a lack or excess of a colorant organism — melanin, black or brown color. Heterochromia at animals always predetermines the fact of one eye of blue color at animals.
Heterochromia not always happens hereditary, sometimes eyes change color owing to an injury or a disease. Complete or partial heterochromia, sometimes, happens that "snap" which does an animal unique in own way, the universal favourite.
