I was thinking about this a few months back and never figured it out. There are green reptiles, green fish, green birds, green insects, but I don't know of any species of mammal that naturally has any green pigment to its skin or fur. I'm not counting species that have algae living in their hair or something like that, I'm talking about actual green pigment being produced by mammals. For that matter, there's not much in the way of blue or purple for mammals, is there? A prize to anyone who can explain why that might be to my satisfaction.
I was reminded of this by the fact that Katy posted a very blue spider.
