Image on the left is of a barell sponge spawning. In the middle photograph, the pumping action of a sponge is illustrated. A non-toxic yellow dye has been squirted around the base of a purple tube sponge in the Caribbean. Shortly thereafter, the dye is pumped out through the osculum at the top of the sponge. Photo on the right is of branching sponges taken from a travel promotion. To learn more about the basics of sponges visit Sponges, The Weird Wonders of the Seas

With culture-based and molecular methods, considerable progress has been made in characterizing the complex microbial communities associated with Key Largo sponges (Xestospongia muta, Ircinia strobilina, Axinella corrugata, Monanchora unguifera and Mycale laxissima), the sponge Microciona prolifera found in the Chesapeake Bay, and Xestospongia testudinaria from Indonesia.
