[Coral-List] coral reefs scatter light like forests

Dear Doug & Dennis, 
     Perhaps one might recall Prof. Iglesia-Prieto's plenary at 2008 ICRS.  The photobiologist used to demonstrate the effect of the stony coral's corallite skeleton as a light trap for the benefit of zooxanthellae, by shining a laser pointer into it.  It's a dramatic demonstration, and I photographed my Euphyllia ancora skeleton with and without red laser pointer to use in coral talks.

Thanks Doug. This was another interesting talk in the AGU session I 
mentioned earlier. The authors likened the situation to a tree canopy and 
had some pretty interesting instrumentation to measure this. Somewhere I 
read that the coral skeleton can also act as a sort of "fiber-optic" system 
to distribute light. Is my brain just making this up or does someone know 
something about this?
