Because the substance discovered in the whale’s head (spermaceti), which closely resembled sperm in look and texture, it was once thought that the sperm whale’s head was packed with sperm.
Despite not being correct, the term “sperm whale” has been in use since the 18th century and is still in widespread use today.

Who came up with the name sperm whale?
There is little information available on the name’s etymology. It has been in use since at least the 18th century, and whalers or sailors who hunted or witnessed the whale are likely the originators.
Early naturalists who researched the whale’s anatomy may have also used the moniker. In the 19th century, the term “sperm whale” spread worldwide and is currently used to refer to the species.
Why do sperm whales have oil in their heads?
The spermaceti organ, a sizable organ in the skull of sperm whales, houses the waxy substance known as spermaceti. The spermaceti organ and the spermaceti contained within it serve unknown purposes.
There are numerous theories, nevertheless, regarding its function. According to one idea, the spermaceti aid in the whale’s ability to control its buoyancy in the water, which permits it to dive deep and stay underwater for extended periods of time.
The spermaceti may also serve as a sonar lens to focus the whale’s echolocation noises, according to another idea. The organ may potentially play a part in the thermoregulation of whales.
In any case, it is obvious that the spermaceti organ is crucial to the life of the whale.
What is Spermaceti?
In the sperm whale’s head, there is a waxy material called spermaceti. It is a wax esters and triglyceride hydrocarbon blend.
It has a very high melting point, is white, and resembles wax. It was once utilized in products like candles, soap, cosmetics, and others. Because it produces a brilliant, smokeless flame, spermaceti was once highly prized and used as a lubricant and in the manufacture of excellent wax candles.
Because it burns brilliantly and with minimal smell, it was frequently employed in oil lamps. Spermaceti is currently less frequently utilized since other materials have mostly taken its place.
