Properties of Water

"Water is about 800 times more dense than air, and 50 times more thick and viscous. Although the chemical formula of water is H2O, it actually contains about 95 percent less available oxygen than air does. All the organisms that live in water have to deal with those chemical and physical properties in some way." 
- Dr. Melanie L. J. Stiassny, Curator of the Milstein Hall of Ocean Life
