External and Internal Anatomy
The most unique biological feature of the sperm whale is its complex nasal system, housed within the forehead.
• Spermaceti Organ: A large reservoir located above the skull that contains high-quality spermaceti oil. It is believed to assist in both echolocation and buoyancy control during deep dives.
• The "Junk": A tissue structure below the spermaceti organ composed of fatty compartments, which also plays a role in focusing sound for echolocation.
• Asymmetrical Blowhole: Unlike most cetaceans, the sperm whale has a single blowhole located at the front-left of its head.
• Narrow Lower Jaw: Features 20–26 pairs of large, cone-shaped teeth that fit into sockets in the toothless upper jaw.
• Skeletal Structure: The skeleton consists of a massive, bowl-shaped skull (the "amphitheatre") that supports the heavy nasal complex, followed by a long vertebral column.

Historical anatomical diagrams of
sperm whales---

date back centuries, reflecting the transition from maritime myth to scientific observation.
17th and 18th Century: Early Stranding Records
Early depictions often came from artists observing beached whales.
• Jan Saenredam (1601): One of the most famous early illustrations shows a beached sperm whale at Beverwijk. These early works often focused on the scale of the animal compared to people, sometimes inaccurately depicting the anatomy because the carcass was collapsing under its own weight.
• Scientific Observation (1760s): By the late 18th century, stranded specimens like the one at Whitstable (1763) allowed for more detailed sketches that began to correctly identify the block-shaped head and lower jaw.
19th Century: The Whaling Era and Thomas Beale
The most significant leap in sperm whale anatomy occurred in the 1800s, driven by the whaling industry.
• Thomas Beale
(1839): A surgeon on a whaling ship, Beale published
The Natural History of the Sperm Whale
. His diagrams were some of the first to accurately map the internal "case" (spermaceti organ) and skeletal system based on dissections performed at sea.
• Frederick Cuvier
(1836): His natural history works included detailed lithographs that categorized the sperm whale (Physeter macrocephalus) among other cetaceans, providing a more standardized biological look at the species.
Evolution of the "Spermaceti" Diagram
Historic diagrams often focused specifically on the head, as whalers were primarily interested in the spermaceti oil. You can see the progression from simple "oil tank" sketches to complex maps of the junk and nasal passages used today.
