Not The Best Pets

When I visited the museum last year, to see the komodo dragons, the exhibit placards claimed that these beasties didn't have true venom.

Now - it's back to the venom theory!

It had been widely believed that deadly bacteria in the carnivorous lizard's mouth helped kill its prey. 

But magnetic resonance imagery has for the first time uncovered venom glands containing a shock-inducing poison which increases blood flow and decreases blood pressure, scientists say.

Thanks to the MRI,
we know how they make things die.
