[QUOTE There are a lot of young folks on this board and thankfully their maturity rivals that of many adults. I'd hope that Mr. B could take a few lessons from some of his peers who are genuinely here to learn. ]
I find it funny that you say he should grow up, when you guys are just yelling at him and calling him a liar and other names. It makes sense that the sponge could grow taller than the water line. Trees grow not only at the top, but also the bottom, if that were not the case, trees would all look as thin as bamboo their whole life. The bottom of the sponge is growing, pushing the top out of the water, and the part that got pushed above water has died. The only thing that seems too good to be true is the growthrate, but hey, I hope that he IS telling the truth b/c that would be pretty cool to be able to come across more of these corals.
