Solution:

Albinism is the “congenital absence of any pigmentation or colouration in a person, animal or plant, resulting in white hair and pink eyes in mammals.” Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV and their lack of camouflage to avoid predators. Albino animals have characteristic pink or red eyes because of the lack of pigment in the iris allows the blood vessels of the retina to be visible.
