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.
I don’t know how relevant this is but I heard human eyes are very good at picking shades of green out. Maybe mammals are generally good at spotting greens and so hiding as a green thing doesn’t work as well. Just a guess though
From what other posters are saying, it may be the other way around? That is, most mammals cannot see green, so it doesn’t matter from a camouflage perspective among mammals. Humans (and primates in general) are an outlier in this repect.
Bird of prey can, though, so there’s that.
Word! That’s cool
I thought veritasium explained in his night vision video that this wasn’t the case? I’m not sure though.
I thought Veritasium was a Harry Potter spell but apparently I should have already known and watched a YouTube video before posting my silly thoughts.
