火山列岛 19

Being good long-distance travellers,

fairy terns island-hopped their way here to French Polynesia.

The ancestors of these blue lorikeets, however,

were brought here by some of the earliest Polynesians.

It could be described as the ultimate honeymoon destination.

Though the waters off these shores don't always appear too inviting.

Blacktip sharks have adapted to swim in less than a foot of water.

They come to these shallows to hunt for smaller fish.

Like Kingman Reef,

all signs of these islands' volcanic past have long since disappeared.

But without it, land could never have got started here.

In the very west of the Pacific, however,

volcanoes have had a helping hand.
