Albino Blue Crab Found

[Noto]

has made me think, does every animal posess whatever it is needed to be an albino- ie can there be an albino of everything?

Any animal that has pigment can be an albino. But not all albinos are white- some animals have structural colors that are unaffected by production of pigments. For example, many normally green frogs and snakes are blue when albino.
