hypopigmentation in the wild. albinism is but one form of hypopigmentation, and is seen here in the kangaroo, dolphin, deer and racoon, where there is a complete absence of melanin. 

the rest, save the bear, are examples of leucism, another form of hypopigmentation, where the pigment cells in the eyes remain unaffected. unlike albinism, it is caused by a reduction in multiple types of pigment, not just melanin. and as with the zebra in this post, it can result in only partial hypogigmentation.

the kermode black bear here actually has dark skin, and get its white fur from a recessive mutation of the same gene associated with red hair in humans. (x, x, x, x, x, x, x, x, x)
