Komodo dragons have iron-coated teeth, scientists find (www.theguardian.com)

With their huge size, venomous bite and the fantastical connotations of their name, Komodo dragons seem like the stuff of legend.

Now, that status has been elevated further: scientists have discovered that their teeth are coated with a layer of iron that helps keep their serrated edges razor sharp.

It is the first time such a coating has been seen in any animal, and one the researchers describe as “a striking and previously overlooked predatory adaptation in the Komodo dragon”.

The coating was discovered when researchers noticed that the tips and serrated edges of Komodo dragons’ teeth were covered in a layer of orange pigment. On closer inspection, the enamel was found to contain concentrated iron that makes the teeth extra hard and resistant to wear, helping the dragons rip and tear their prey apart.

Komodo dragons are the largest living reptiles, growing to more than three metres in length and averaging 80kg in weight.

Ok, I had to look it up: it’s apparently been debunked that Komodo Dragons have dirty infectious bites and it’s actually related to a highly debated saliva-like mouth secretion that some classify as venom.

Damn
