Badass Newt!

Check out this article on a newt that can move its ribs to turn their "spear-sharp" points into defensive spines, which entails STABBING THE RIBS OUT THROUGH ITS SKIN.  That's right, no convenient pore.  The spines cut through the skin every time!  It's okay, though, because the newts heal really fast.  It's Wolverine in newt form!  This is yet more evidence that biology is way more exciting than other sciences.
