The Facts

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

• In a paper published Wednesday, the scientists wrote that iron in the cutting edge and tips of the world's largest lizard species' teeth stain them orange.

• The study found that this "novel adaptation" gives the enamel of one of Earth’s fiercest reptile species the extra strength to rip apart its prey.
