Moon jellies are drifters, using jet propulsion to move.  Lacking a brain, a heart and bones, they are composed of 95-97% water, 3% protein and 1% minerals.  The Moon Jellies, above, have traveled in smacks through all the oceans of the world for the last 650 million years.  Sea Science at the Vancouver Aquarium, has more fascinating facts about jellies: http://www.vanaqua.org/home/ as does USGS, where this photo resides: http://www.usgs.gov/
