Sorry for the hijack but this is a favorite subject of mine so I thought I'd butt in. I found it took a very long time for an elegance to heal completely. I've cut up trachyphyllia before and within a few weeks the cut area has completely closed up. With the elegance, it took two or more months for the cuts to heal over. However the trachyphyllia I've been cutting has been in my system much longer than the elegance.
