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.
Exactly why these skinks are filled with this toxic substance and why it doesn’t kill them is something of a mystery. But new research published in Science Advancesmakes an important step towards answering these questions.
