If you were to see certain New Guinea skinks lose their tails, you'd notice that their blood isn't the usual red colour we're used to but rather a virulent shade of green.
What's even more bizarre is that the substance that's responsible for the green colour of the lizards' blood (and bones, tongues, muscles and mucous membranes) would be toxic in other animals if they carried it in such large amounts.
