What causes the pink or ruby red appearance in albino ferret eyes?
Answer
Visibility of the blood vessels within the eye structure
The reddish or pinkish tint observed in the eyes of an albino ferret is not due to a specific red pigment being present. Instead, it is an optical phenomenon where light reflects off the capillary network and blood vessels located beneath the iris. Since the iris itself lacks melanin, it offers no obscuring color, allowing the viewer to see the underlying red coloration of the circulatory system within the eye. This visibility is unique to animals completely lacking pigment across their entire body structure, including the ocular tissues.
