While white cats simply have a gene coded for white fur, albino cats have a total lack of color pigmentation in their skin, fur, and eyes. No. No melanins are produced anywhere in the body. 'We see wild rabbits, guinea fowls. Red-eyed white rabbits (also known as ruby eyed whites) are albino rabbits who don’t even have any pigment in their eyes. [47], Albinistic individuals of the following shark species have been reported:[48][49], A study published in 2006 reported albinistic individuals of the following ray species:[49], There are several reports of albino lampreys and it has been estimated that this occurs at a frequency of one in 100,000 normal individuals. Albino snakes can remain in the sunlight for several hours with minimal harm. cch3 – Inhibits production of pheomelanin pigment only. In mammals, albinism is occasionally associated with hearing impairments.

The only known albino alligators are in captivity. Similarly, Mexican blind cave fish (Astyanax mexicanus) do not differ in hearing sensitivity from the normally pigmented and eyed surface-dwelling populations. Albinism doesn't only affect land animals—sea creatures, like humpback whales, can be born without pigmentation, too. Albino dolphins were first sighted in the Gulf of Mexico in 1962. For snakes that are usually patterned in colours, they appear as a faint blue, peach or yellowish. The structures themselves are colourless.

Many animals have pigments other than melanin, and some also have structural colours. They might also spend more time moving their head around to scan their surroundings and inspect objects. The costs of albinism for marine mammals may include reduced heat absorption in colder waters, poor camouflage from predators, increased sensitivity to sunlight, and impaired visual communication. But the suppression of melanin in their eyes is incomplete. In normal circumstances, the differences in their eyes doesn’t cause any pain or discomfort either.
