spermaceti in Science
spermaceti
  (spûr'mə-sē'tē)   
A white, waxy substance that is obtained from the head of the sperm whale and sometimes other whales, porpoises, and dolphins, and was once widely used to make candles, ointments, and cosmetics. Spermaceti is a liquid at body temperature and consists primarily of fatty alcohols and esters of fatty acids. Spermaceti is produced by the spermaceti organ, a huge melon-shaped sac that may function as a battering ram in aggressive behavior between males.
