When giant clams spawn, |
[00:02.81] |
they expel millions of eggs into the water. |
[00:06.55] |
And when one starts, |
[00:08.62] |
all the others quickly follow. |
[00:10.59] |
The sea soon turns cloudy with life. |
[00:15.30] |
Giant clams can live for over 50 years. |
[00:19.19] |
But it's their death |
[00:21.11] |
that is crucial to the creation of land in Kingman Reef. |
[00:25.31] |
These few hundred metres of coral rubble |
[00:28.60] |
and dead clams |
[00:29.86] |
are the only visible signs of Kingman above the water, |
[00:33.50] |
providing a valuable rest stop to passing voyagers. |
[00:37.41] |
Eventually, seeds brought by ocean currents and birds |
[00:41.10] |
will turn it into a new island. |
[00:44.08] |
And once vegetation is established, |
[00:46.96] |
wildlife is never far behind. |
