A newt that slices and dices

The Spanish ribbed newt has an interesting method of dealing with perceived threats. The creature activates its ribcage like mini switchblades, forcing them through its own skin. Even more remarkable, the newt’s highly adapted immune system and collagen-cased bones allow it to heal quickly and without risk of infection, which makes it one job interview away from a position with the X-Men.
