Sperm Whale

They are named after the waxy substance—spermaceti—found in their heads. The spermaceti is an oil sac that helps the whales focus on sound. Spermaceti was used in oil lamps, lubricants, and candles. Sperm whales were a primary target of the commercial whaling industry from 1800 to 1987, which nearly decimated all sperm whale populations.

The name did not come from sperm cells.

• Singular: sperm whales

• Plural: sperm whales

Sperm whales are mostly dark gray, though some have white patches on the belly. They are the only living cetacean that has a single blowhole asymmetrically situated on the left side of the crown of the head. Their heads are extremely large, accounting for about one-third of their total body length. The skin just behind the head is often wrinkled. Their lower jaw is narrow, and the portion of the jaw closest to the teeth is white. The interior of the mouth is often bright white as well. There are between 20 and 26 large teeth on each side of the lower jaw. The teeth in the upper jaw rarely break through the gums.

Sperm whale flippers are paddle-shaped and small compared to the size of the body, and their flukes are triangular. They have small dorsal fins that are low, thick, and usually rounded.

One of the deepest-diving mammals, sperm whales typically dive between 400 and 1,500 meters, with a maximum recorded depth of >2,000 meters, possibly as much as 3,000 meters, and a dive duration of 45 to 90 minutes. Sperm whales' flexible lungs and collapsible ribs allow them to withstand exceptionally high pressures. The spermaceti organ may help in pressure correction, buoyancy, and sound generation.

Atop the whale's skull is positioned a large complex of organs filled with a liquid mixture of fats and waxes called spermaceti. The purpose of this complex is to generate powerful and focused clicking sounds, the existence of which was proven by Valentine Worthington and William Schevill when a recording was produced on a research vessel in May 1959. The sperm whale uses these sounds for echolocation and communication.

The sperm whale's tail flukes offer strong vertical propulsion for deep dives, and it swims at a typical pace of 5–7 km/h with burst speeds of about 20–30 km/h. This species uses echolocation, which produces the loudest biological sound (up to 230 dB), for both hunting huge prey and deep-sea navigation.

Sperm whales eat fish and squid, including giant and colossal squid that grow more than 50 feet (15 meters) long. Much of the sperm whale's life is spent under the sea, far from land, so the species largely remains a mystery. Individuals are born into groups composed of about a dozen females and their young.

Like elephants, females tend to stay together, but males leave the group as early as their fifth year. Young males form groups with others about their age. As they mature, the males break into smaller groups; older males usually live alone. The bulls tend to stay in cooler, higher latitudes, while the females remain in warmer waters. Males are ready to breed at 18 years old but don't reach full size until about 50. They return to female ranges to mate.

Reproduction

• Mating System: Polygynous; male–male competition.

• Breeding Interval: Every 4–6 years.

• Gestation: ~14–16 months.

• Calves:

  • Born ~4 m long, about 1 ton.

  • Nurse for 2+ years; remain with mother’s group for years.

• Sexual Maturity:

  • Males: ~18 years (though breeding dominance comes later)

  • Females: ~9 years

The sperm whale's social behavior is as follows: adult males are primarily solitary and only join groups for mating, whereas females and juveniles form stable social units (10–20 members). They are extremely intelligent and have sophisticated social learning skills. They communicate via structured codas, which are click patterns that can act as dialects.

Sperm whales have historically been heavily sought for oil due to whaling (18th–20th centuries). With the exception of infrequent defense incidents, sperm whales today are typically shy but not hostile. Sperm whales are known for their curiosity about humans and research vessels, and humans permit whale watching from a distance because they perceive sperm whales as either a natural threat or an ally.

Threats

• Past whaling drastically reduced populations.

• Ship strikes.

• Noise pollution interfering with echolocation.

• Fishing gear entanglement.

• Declining squid populations due to climate change.

• Pollutants such as heavy metals and plastic ingestion.

Conservation Status

• IUCN Red List: Vulnerable (VU)

Conservation Efforts

• Protected by the International Whaling Commission (IWC).

• Many regions enforce marine protected areas.

• Modern ship-strike and noise management measures.

• Awareness campaigns against illegal pet trade.

These cetaceans are found in temperate and tropical waters throughout the world, usually in pods (groups) of about 15 to 20; solitary males, however, may wander into colder regions. Prior to whaling, sperm whales may have numbered 1.1 million worldwide, according to the American Cetacean Society.

In the 2600s and 2700s, during The Recollections of Queen Arianna (TROQA) saga, the "Sky People" or Terrans from Earth brought sperm whales to two exoplanets that resembled Earth: Berbania from Ursa Major and Reinachos from Cygnus. Despite the death of our planet, this species is recovering from endangerment or near extinction thanks to conservation initiatives. Human activities for rewilding and game hunting produced this species, but they backfired because the sperm whale pup became an invasive species. The whale inhabited two exoplanets that were similar to Earth in terms of climate and environment.

Sperm whales, aka cachalots, are impossible and immoral in our universe, in contrast to Rapunzel's universe (combined with Assassin's Creed, Marvel, Capcom, and others). Their primary causes were their enormous size (up to 60 tons), sperm whales' need for deep-water habitat and long-distance travel, their complex social lives, legal safeguards, and their inability to be housed in captivity (none were kept alive for an extended period of time) due to their echolocation abilities.

Sperm whales are a lost species of cetaceans that survived for 3000+ years, along with Commerson's dolphin and harbor porpoise. They survived overexploitation and were fully protected by conservationists and the royal family.
