Talk:Giant barrel sponge

Readers of this article want to know...
...is it really the biggest of it's kind? Were prehistoric sponges, any of them, even bigger? What about way back in the glory days of the sponges, the early precambrian times? Why don't they grow any bigger? Why aren't there massive tree-sized sponges like there are plants? Chrisrus (talk) 03:49, 13 June 2011 (UTC)

Perspective
Someone should interview an elderly giant barrel sponge and ask what he or she thinks of the last 2,000 years of human history on the planet we share. Sca (talk) 14:39, 23 July 2013 (UTC)
