[Coral-List] Acropora prolifera issues

The problems of coral allorecognition and xenorecognition as well chimerism are still waiting attention.  To mention also the astonishing growth in aquaria.  -- Vassil

Yep, I have seen also, and a cervicornis branch growing seamless bottom up right through the middle of a palmata frond.

Somewhere in my mountain of slides, I have photos of both A. prolifera and A. cervicornis (based on visual character and not genetics)growing from the corner of a healthy A. palmata. Any ideas on what this means?
