Sponge Website??

[Murminator]

Anyone have a good website on sponges??? I cannot find a good one unless you wanna scrub your feet with them or use them as tampons:eek: I have a big funky one growing in my sump that look like an alien spacecraft. It started out a month ago about the size of a pea covered in spines, now it's a little smaller than a ping pong ball with like 3" spikes coming out it and it's off pink kinda peachy colored. I can't get a good pic without disturbing it.
So if someone has a good site bookmarked thated be great I wanna find what the heck it is. :mrgreen:
