Birds, fish, reptiles, amphibians, insects? Sure. But no mammals.

So I had to google it. Apparently, there is a sloth that moves around so slowly moss grows all over it and it doesn’t care. So it may appear green, but only in the sense that it wears it.

    Wow, that is fascinating!

    Makes me wonder about the other direction, going into the near infrared as opposed to UV. I remember from a class in remote sensing that many plants are actually most reflective in that band (more so than in green, even). NIR air photos are often used by biologists to get an indication of the health of a forest. But I have no idea whether animals also reflect NIR? It may be that most animals cannot see in that band in the first place, so it would not offer any camouflage advantage.
