Surprising Snow-White Animals of Your Winter Dreams

Spotting a rare, snowy white animal that would typically be colourful is a surprising treat, and stunningly beautiful. White feathers or fur can be caused by genetic conditions including albinism and leucism. Albinism is a genetic mutation in which the body cannot produce melanin pigments. Leucism is another genetic peculiarity that causes white coloration, but the animal may have some pigments, such as giving them blue eyes or colour patterning. Sometimes the white colour can make animals more vulnerable to predators since they stand out. However, the coloration can also help them blend in. Albino and leucistic animals can also be dangerously susceptible to sunburn. Owners of pets with albinism and leucism can make accommodations to protect their companions.
