The other theory suggests that the organ is used to focus and control the beam of sound that the whale uses for echolocation. Login or upgrade your account. Encyclopedia of Marine Mammals. I would encourage anyone even remotely interested in whales to go on a whale watch and see a whale up close. The most likely primary function of the spermaceti organ is to add internal echo or resonator clicks to the sonar echo location clicks emitted by the respiratory organs. The spermaceti removal process, however, had not really changed from the time when the men of the Essex whaleship retrieved spermaceti from the sperm whales which they had captured.
Whale oil was widely used in the First World War as a preventive measure against trench foot. One source says ten barrels, but this was from a very large bull. However, refined products from petroleum began to replace some of these other products as well and even whale ambergris, the valuable base for perfumes, was finally replaced by synthetics. It appears that some whales may fall into a deep sleep for about 7 percent of the time, most often between 6 p. The proportion of wax esters in the spermaceti organ increases with the age of the whale:

In the photo are waxy cakes of semi-processed whale oil being readied for the extraction of Taut-Pressed whale oil. The oil from bottlenose whales was sometimes called "Arctic sperm oil".
First discovered in ancient times as a substance of unknown origin which would wash ashore, it wasn't until the whaling era that the true source of the material was found. This liquid was bottled and sold as "winter-strained sperm oil". This process helped purify these oils, which ranged from straw yellow to clear, while the remaining particulate or solids descending to the bottom of the vats were largely used in soap making. Spermaceti forms brilliant white crystals that are hard but oily to the touch, and are devoid of taste or smell, making it very useful as an ingredient in cosmetics, leatherworking, and lubricants. Sperm whales celebrate the discovery of new oil wells in Pennsylvania. The Blackfish is known today as the Pilot Whale.
