When I lived in Hawaii I became intimately familiar with this sound (if
it's the same one) -- it's the sound of fish grazing on coral or rock,
their teeth striking the hard reef!
I remember the sound as very non-directional, impossible to localize, but
if you were nearby a fish or two, you could correlate some of the "clicks"
you heard precisely with them nibbling at the reef... :)
