Sperm whales were once quite abundant in the Gulf of Mexico, but due to commercial whaling operations, they are seldom seen in this area anymore. Worldwide however, sperm whales populations are more stable than that of many other whales, although they continue to be listed as endangered by USDI (1980). The sperm whale is now the most abundant of the great whales, having been hunted with less intensity that the baleen whales. Worldwide, sperm whales number about 1,500,000.
