Only a handful of bats made it here,the only mammals to do so,

and there are far fewer birds

In the absence of ground predators,

invertebrates evolved into monsters

This millipede is one of the biggest of its kind,

running almost a foot long

Its diet of rotten vegetation may have sustained its ancestors on their long journeys to these distant shores

But how did they get here?

Perhaps more surprising,

two species of frog also made it to Fiji

Surprising because adult frogs quickly die in saltwater

But the ancestor of this frog may have arrived here as a tadpole

Tadpoles normally need pools of freshwater to develop in,

but these actually mature inside the egg

So, on long journeys, these eggs would have been like little survival capsules

But the question remains - how did they ever reach these islands?

Maybe the same way as Fiji's most intriguing castaway of all
