A good design, indeed. Thanks for the ping.

Scientific American has picked up on it as well. Amazing Sponges

Here's an interesting little 'snippet' from their article:

"each spicule is capped with a cross-shaped antenna of sorts. The flat spokes of the antenna capture light, which then travels directly down the silica tube of the spicule to the garden of green thriving at the base."

Boy that evolution sure is crafty. And what a choice of words the author used!

Hey, neat two of em(species that is). But they don't say this one has algae in it. I wonder if the shrimp need mood lights?
