[Coral-List] bleaching on the Great Barrier Reef (Alina Szmant)

[Douglas Fenner]

If they got overgrown by algae, they are almost certainly dead.  Which fits
with what I said that it is quite hard to tell the difference between
bleached and newly dead, even if you are just inches from them (let alone
an airplane).  Live tissue on a bleached coral is clear, so it is
especially hard to see.  You see the white skeleton, just like when the
coral is just died.  Hard to see clear tissue.
Cheers, Doug
