Another oddity I recently saw a picture of was an albino sailfish caught in the Gulf of Mexico. Can't find that link though. Has anyone kept any really rare color morphs of stuff?

I believe it is a type of albinoism, but I guess you can say color morph is a type of albinoism too.

I think there's differences...yellow forms said to have 'xanthism', and black forms are said to have 'melanism'...that shark looks like it has *some* pigment in it. The only color morphs I can think of off the top o' me head are the yellow belly hippos, orange tail emperors, black ocellaris clowns, yellow and black puffers...I don't know if this is the same kind of thing though.

"Among wild animals, color aberrations sometimes occur. The most familiar is albinism, a genetically determined trait in which no pigments are produced. Even the iris is unpigmented in a true albino, and the eye looks pink. ("Leucistic" animals such as polar bears, which are normally all white, have pigmented eyes.) Varying degrees of albinism occur in all kinds of animals; in birds, sometimes only individual pairs of feathers on opposite sides of the body are affected. Albinos are so obvious against a natural background of green or brown that they often are easy targets for predators, so there are few true-breeding albinistic populations in the wild.
Other color variations in animals include melanism (an "over-abundance" of melanin pigment that makes an animal abnormally dark); xanthism (abundant yellow pigments); and erythrism (abundant reds). One species of South Carolina reptile--the Southern Hog-nosed Snake--is known to produce individuals with any of these colorations. In several suburban locations in the U.S., there are all-black colonies of melanistic gray squirrels maintained by humans who selectively cull out "less desirable" gray individuals."

PS There are also some Centropyge with xanthic forms...

The lack of pigment in it's eye makes me agree with your assessment of albinoism.
