[Coral-List] test tube corals in Brazil

[Douglas Fenner]

Also, I think sperm are easy to freeze.  Eggs and larvae are hard to freeze
and survive thawing.  You need eggs or larvae if all the adult colonies on
the reefs die and you want to get them started again.  But maybe people are
now successfully freezing eggs and/or larvae.  The hurdle is to not allow
ice crystals to break membranes.  I read that it is possible to substitute
something else for the water and then freeze things.  When you defrost, you
replace that thing with water, I believe.  I'm not involved so I could
easily be wrong about some of these things.
