Ira Posted November 15, 2004 Report Share Posted November 15, 2004 Sounds exactly like sponges. Little free filters. Quote Link to comment Share on other sites More sharing options...
chimera Posted November 15, 2004 Author Report Share Posted November 15, 2004 Interesting,... Sponges are also the only animals known to commonly maintain symbioses with cyanobacteria, and recent work suggests that both bacterial and/or cyanobacterial symbionts are present in the majority of sponges REF: http://www.advancedaquarist.com/issues/april2004/invert.htm Quote Link to comment Share on other sites More sharing options...
