Fluorine Is a Major Constituent of the Marine Sponge Halichondria moorei.
Fluorine constitutes about 10 percent of the dry weight of the marine sponge Halichondria moorei. The fluorine occurs as potassium fluorosilicate, which is a potent anti-inflammatory agent. A closely related sponge living in the same habitat does not contain any fluorine. The habitat was found to be free of fluorine except for the small amount naturally present in seawater.
