This tiny South Pacific island may not look like much.
But it was once a mountain that towered above the waves.
Now it barely breaks the surface.
Yet still it attracts a spectacular array of wildlife.
There are thousands of islands just like this scattered across the Pacific,
and all are teeming with life.
So what has reduced the mountains of the Pacific to this?
Almost seven miles deep,
the Pacific is the deepest body of water on the planet.
But sometimes, the seabed shoots to the surface.
Behold one of nature's rarest sights - the creation of a new island.
This is Kavachi in the Solomon Islands,
one of the most active undersea volcanoes in the world.
In the last 100 years, Kavachi's emerged above the waves just a handful of times,
but so far to no avail.
Powerful waves keep sweeping its efforts away.
