The Facts

• Scientists have found a "striking" and "predatory adaptation" in the Komodo dragon: a layer of iron coating on its teeth, keeping its "serrated edges razor sharp."

• According to a paper published Wednesday in Nature Ecology & Evolution, iron in the cutting edge and tips of the world's largest lizard species' teeth stain them orange.

• The scientists claim this "novel adaptation" gives the enamel of one of Earth's fiercest reptile species the extra strength to rip apart its prey.
