Delve into the awe-inspiring world of these majestic deep-sea giants.
1. The Largest Brains on the Planet Belong to Adult Sperm Whales.
While the human brain weighs around 3 pounds, a sperm whale's brain can reach an astonishing 17 pounds. However, proportionally, humans have the edge: our brains make up 2 percent of our body weight, compared to just 0.02 percent for sperm whales. Perhaps it’s best to consider it a tie.
2. The Name 'Sperm Whale' Comes from a Unique Waxy Substance They Produce
Early whalers discovered this material, which originates from a barrel-shaped organ in the whale's head, and mistakenly believed it was related to reproduction. They named it 'spermaceti,' derived from the Latin term for 'whale seed.'
Curious about the purpose of this substance? You're not alone. For hundreds of years, scientists have debated its function. Some believe spermaceti aids in buoyancy control, while others argue it acts as a cushion to protect males' brains during aggressive mating rituals. [PDF] Another theory suggests it plays a role in enhancing the whales' long-distance communication.
3. Sperm Whales Have a Deep-Sea Appetite for Squid, Including Giant Squid

No squid enthusiast on the planet can match a sperm whale's appetite for these cephalopods. Females consume an impressive 700-800 squid daily, while males typically settle for a more moderate 300-400. Analysis of their stomach contents shows that giant squids are just one of many species sperm whales feast on. However, the battle scars from these encounters, visible as suction cup marks, suggest that giant squids are a challenging prey.
4. Sperm Whales Excel in Deep-Sea Diving
These marine giants are known to plunge to depths exceeding 3,280 feet and can hold their breath for up to 90 minutes.
5. They Reign as the Largest Toothed Predators on Earth
While blue and fin whales are larger in size, sperm whales stand out as formidable hunters with their sharp, conical teeth. Interestingly, only their lower jaws are equipped with teeth, which fit into sockets in their toothless upper jaws.
6. Male Sperm Weigh Nearly Three Times as Much as Females
The differences between male and female sperm whales go beyond size. Females thrive in close-knit social groups, whereas males tend to live solitary lives once they reach adulthood.
7. The Tale of Herman Melville’s Moby-Dick Was Inspired by a Real-Life Rogue Sperm Whale

This astonishing event occurred in the South Pacific on November 20, 1820, when a massive male sperm whale rammed the New England whaling ship The Essex. The 21 crew members, battered and desperate, abandoned the doomed vessel, jumping into three small whaleboats before it sank. What followed was a grueling 3000-mile odyssey across treacherous waters. Many succumbed to the harsh conditions, and some survivors resorted to cannibalism before finally being rescued near Chile.
8. Sperm Whale Lower Jaws Sometimes Twist into Unusual Shapes
Over the years, researchers have discovered numerous healthy sperm whales with oddly deformed jawlines, including some with lower jaws twisted into a spiral or corkscrew-like form.
9. Sperm Whales Possess the Ability to Identify Each Other by Voice
During deep dives, sperm whales maintain communication with their pod members through distinctive clicking sounds. Remarkably, even when two whales produce identical click patterns, their companions can distinguish between them due to subtle, individual vocal nuances.
10. Spermaceti Played a Key Role in Lighting the Industrialized World
The material can be used to create smokeless candles, a discovery that nearly led to the extinction of these magnificent creatures. In the 18th and early 19th centuries, spermaceti was highly sought after for lanterns, streetlights, and lighthouses. Tragically, fulfilling this demand resulted in the deaths of approximately 236,000 sperm whales just in the 1700s. This excessive hunting caused the industry to collapse as whale populations dwindled. By 1846, profits had significantly decreased, and the cost of spermaceti had doubled. Thankfully, a new solution emerged when Canadian geologist Abner Gesner invented a kerosene-based lamp fuel that lasted longer, effectively ending the sperm whaling industry.
11. Deceased Whales Can Explode
If you come across a beached whale carcass, it’s wise to keep your distance. On multiple occasions, decomposing whale bodies have exploded violently, shocking onlookers. The buildup of gases during decomposition can cause the carcass to rupture, releasing a foul-smelling burst of internal matter into the air.
Interestingly, sperm whales are often involved in such incidents. In 2006, a decomposing sperm whale made global news when it exploded, scattering its organs across a busy street in Taiwan. More recently, another incident occurred on the Faroe Islands, as seen in this video (viewer discretion is advised).
