I thought Majanos too, but I did not want to bias anyone's opinion. It has a form much like other ones ID'd around the net (but there are often conflicting).....
One factor is size? Do majanos reach a size of 3in x 3in? Then split and remain the same size......seems like majanos I've seen start small, like they have a different mechanism for repoduction, or just split tiny buds.
Color, has anyone seen a majano with neon green base?
I have also noticed there seem to be any signs of nematocysts (sp?) stinging adjacent corals.....
Any more info or a good technical reference would be greatly appreciated!
