Komodo dragon has iron-coated teeth to rip apart their prey

A new study has discovered that the serrated edges of Komodo dragon’s teeth are tipped with iron. Led by researchers from King’s College London, the study gives new insight into how Komodo dragons keep their teeth razor-sharp.

Komodo dragon is the largest living species of monitor lizard, averaging around 80kg. Deadly predators, Komodos have sharp, curved teeth similar to many carnivorous dinosaurs.

The team used advanced imaging and chemical analysis to observe that the iron in the enamel of Komodo dragon is concentrated into a thin coating on top of their tooth serrations and tips. This protective layer keeps the serrated edges of their teeth sharp and ready to be used at a moment’s notice.
