In the past, whalers hunted sperm whales for spermaceti, fine oil used to make high-quality candles and lubricants. Estimates vary widely regarding the present population of sperm whales. The American Cetacean Society states, "Most recent estimates suggest a global population of 300,000 animals, down from about 1,100,000 before whaling."

The sperm whale population is slow to recover because these animals mature late and have few offspring. Sperm whales are listed on the U.S. Endangered Species List. Hunting of sperm whales is banned nearly worldwide.
