Well here we are on the reef flat
and we're looking at, what I like to think as
as the heroes of the beaches
everyone like a clean beach,
everyone likes a sandy, white tropical beach
that's the ideal thing, and here we've got a lot of
Holothurians, otherwise known as
sea cucumbers of trepang
they pick up all the sand
out of the ocean
and they eat it, and digest it and take all the
nutrients and dirty particles out of it
and just leave the clean sand
so these guys are the ones that are making
the clean, beautiful, white tropical sand
cleaning up our sand for us.
great job guys.
