[00:00.58]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.
