There's no such thing as a giant flying lizard that breathes fire. But the natural world has plenty of real dragons, and some of them can fly

If you think of dragons as supersize reptiles with a nasty bite, the Komodo dragon is the real deal. Up to 3m long and weighing as much as 70kg, they are the world's biggest lizards.

At the smaller end of the real dragon scale we have the millipedes. Dragon millipedes are found throughout South East Asia and named for the elaborate spikey protrusions, or 'paranota', that are thought to shield their many legs.

One of the most striking species was discovered in 2007 in Thailand, living in a limestone cavern. Researchers came across the shocking pink dragon millipede sitting in the leaf litter. At 3cm long, it is one of the largest dragon millipedes.
