A Legendary Pact Between Orcas and Humans Just Got More Mysterious

Along the rugged coastline of Twofold Bay in Eden, New South Wales, the ocean holds memories of a saga that sounds more like ancient folklore than documented history. For decades, maritime history recorded an astonishing pact between human whalers and a wild pod of killer whales. At the center of this extraordinary cooperative alliance stood “Old Tom,” a male killer whale (Orcinus orca) who reportedly served as the charismatic leader of a 30-member pod known to locals as the “Killers of Eden.”

According to legend, Old Tom and his pod would actively herd massive baleen whales into the shallow waters of Twofold Bay, alerting human whalers to the hunt by breaching, leaping, and slapping their tail flukes near the shore. Once the whalers arrived in their wooden rowboats to harpoon the giant cetaceans, the orcas assisted in anchoring the prey. In return for their hunting assistance, the humans honored an unwritten arrangement known as the “Law of the Tongue.” The whalers would anchor the freshly killed whale in the bay overnight, allowing the orcas exclusive access to eat their favorite delicacies—the rich, soft tongue and lips of the whale—before retrieving the blubber and bone the following morning.

It was a gruesome yet harmonious arrangement that persisted across generations. However, behind this celebrated tale of human-animal cooperation lies a deep web of scientific contradictions, cultural heritage, and forensic twists. Recent discoveries in genetics, marine biology, and historical conservation suggest that the true story of Old Tom is far stranger, more complex, and ultimately more captivating than the myth itself.

An Ancient Cultural Heritage

While commercial whalers popularized the story of Old Tom in the 19th and 20th centuries, the relationship between humans and killer whales off the southeastern coast of Australia began thousands of years earlier. For at least 10,000 years, the coastal First Australians—specifically the Thaua people of the Yuin nation—maintained a profound spiritual connection with the ocean’s apex predators.

To the Thaua people, orcas were not merely wild animals or hunting tools; they were regarded as beowas, or brothers. Indigenous tradition held that orcas were the reincarnated souls of tribal ancestors, specifically ancestral whalers who had returned to the sea to aid their living kin. Whenever a respected elder passed away, it was believed their spirit entered a newborn killer whale. Thus, when orcas drove baleen whales toward the shore, it was viewed as family members sharing a harvest with their terrestrial relatives.

In the mid-19th century, as European settlers established commercial whaling stations in Eden, Scottish immigrant Alexander Davidson and his family recognized the indispensable value of Indigenous maritime knowledge. Three generations of the Davidson family operated a whaling station at Kiah Inlet from 1860 to 1940, employing First Australian crew members who brought their ancient understanding of killer whale behavior to the commercial operation.

For decades, three successive generations of the Davidson family claimed that the exact same male orca—Old Tom—assisted them on their seasonal hunts. Old Tom was easily identifiable by his physical markers: although relatively small for a mature male mammal-eating orca, he possessed an exceptionally tall dorsal fin with a distinct, pronounced bend toward the right near the tip.

The Breakdown of a Sacred Trust

The delicate balance supporting this cooperative fishery began to crumble at the turn of the 20th century. In 1901, a tragic event shattered the relationship between the Indigenous whalers and their European employers. A killer whale belonging to Old Tom’s pod became accidentally stranded on a local mudflat. In a senseless act of violence, three European settlers killed the stranded animal with wooden stakes.

To the First Australian crew members, this act was not merely animal cruelty; it was the desecration and murder of a spiritual ancestor. Outraged and deeply offended, the Indigenous whalers immediately severed ties with the Davidson whaling station and walked away. Without the Indigenous crew’s unparalleled tracking skills and deep understanding of the orcas, the Davidson commercial enterprise faltered significantly.

The impact was felt in the water as well. The very next season, in 1902, only seven of the original 30 orcas in Old Tom’s pod returned to Twofold Bay. Some historians suggest the highly intelligent pod recognized the danger posed by local settlers; others attribute the decline to the expansion of industrial Norwegian whaling operations further out at sea, which decimated target whale populations and accidentally intercepted pod members.

By the 1920s, the once-flourishing pod had vanished entirely, leaving Old Tom as the lone killer whale returning to Eden year after year.

The final chapter of this partnership occurred in the mid-1920s during a fateful hunt. George Davidson and a crew of neighbors harpooned a small baleen whale with Old Tom’s assistance. As they secured the catch, a fierce gale blew into the bay, threatening to capsize the boat and wash the carcass out to open sea. Desperate to salvage their haul, the whalers made the decision to tow the whale carcass directly to shore without allowing Old Tom his traditional share of the tongue.

Refusing to yield his earnings under the Law of the Tongue, Old Tom clamped his jaws onto the heavy towline, attempting to hold the carcass back. A fierce tug-of-war ensued between the frantic whalers and the stubborn killer whale. During the struggle, the line yanked violently, snapping several of Old Tom’s teeth. Realizing what had happened, the horrified crew reportedly cried out in remorse over injuring their longtime marine partner.

A few years later, in September 1930, the lifeless body of a male killer whale washed ashore near the mouth of the Kiah River. The carcass exhibited severe oral abscesses, leading examiners to conclude that the loss of his teeth had resulted in chronic infections, making it impossible for him to hunt effectively and leading to starvation. Guilt-ridden local residents preserved the remains, donating the complete skeleton to the town, where it became the centerpiece of the newly established Eden Killer Whale Museum.

The Scientific Anomalies Begin to Surface

For nearly a century, the tragic demise of Old Tom stood as the definitive end to an extraordinary chapter in marine history. However, as modern marine biology and forensic science evolved, researchers began taking a closer look at the physical evidence preserved in Eden—and the historical narrative began to break apart under scrutiny.

The first major anomaly centers on longevity. Historical records maintained by three generations of the Davidson family placed Old Tom in Twofold Bay from the 1860s until his death in 1930. This timeline required Old Tom to have lived to an age of at least 90 to 100 years.

In wild killer whale populations, female orcas can occasionally reach ages of 80 or 90 years. Male orcas, however, have significantly shorter lifespans. On average, male killer whales live approximately 30 years in the wild, with maximum recorded lifespans rarely exceeding 50 to 60 years. A 100-year-old male orca would represent an unprecedented biological anomaly.

To resolve this question, scientists turned to dental forensics. Like the growth rings inside a tree trunk, the dentin layers inside dolphin and whale teeth deposit annually throughout an individual’s life. By analyzing thin cross-sections of the teeth preserved in Old Tom’s museum skeleton, researchers determined that the animal was actually only around 35 years old at the time of death.

How could an animal that had allegedly hunted with humans for 70 years be physically aged at just 35?

The 2014 Forensic Breakthrough: A Case of Mistaken Identity?

The puzzle deepened significantly in 2014 during a completely unrelated scientific investigation into South African killer whales. A research team published a paper focusing on a unique, specialized ecotype of killer whales known as “flat-toothed” orcas.

Orca populations worldwide are categorized into distinct ecotypes based on their highly specialized diets and social structures. Transient orcas specialize in marine mammals like seals and baleen whales; resident orcas feed exclusively on fish; and specific coastal populations target sharks and rays. Flat-toothed orcas belong to this latter group, preying heavily on bottom-dwelling sharks and stingrays. Because shark skin is coated with abrasive, sandpaper-like dermal denticles, these orcas experience extreme, uniform wear on their teeth over time, frequently leading to exposed nerve cavities and painful oral abscesses.

Unexpectedly, the 2014 paper included a dedicated section analyzing the skeleton and historical record of Old Tom from Eden, Australia. The researchers raised several startling observations:

Dorsal Fin Discrepancies: While Old Tom was famous throughout his life for an exceptionally tall dorsal fin with a sharp rightward bend at the tip, photographs taken of the deceased 1930 carcass on the beach showed a dramatically different dorsal fin—substantially smaller, noticeably shorter, and lacking the signature rightward bend.

Skeletal Tampering: The skeleton currently displayed in the Eden Killer Whale Museum measures approximately 6.78 meters (22.2 feet) in length—matching the historical descriptions of Old Tom. However, a forensic anatomical audit revealed that when technicians originally mounted the skeleton for public display, they inserted dozens of artificial wooden and material filler discs between the vertebrae. In total, these fabricated spacers added up to 1.34 meters (4.4 feet) of artificial length. The actual living animal was likely only 5.4 meters (17.7 feet) long—far too small for a mature male mammal-eating orca, but entirely consistent with the smaller body size of a flat-toothed, shark-eating ecotype.

Genetic Evidence: In 2023, geneticists successfully extracted and sequenced DNA from the museum skeleton to map its lineage against modern global orca populations. The results yielded another surprise: the specimen shared no direct genetic descendants among modern Australian mammal-eating orcas. Instead, its closest living genetic relatives were found among the killer whale populations of New Zealand—a region famous for stingray- and shark-hunting flat-toothed orcas.

Reconstructing the Truth: The Multi-Tom Hypothesis

When synthesizing the physical evidence, historical photographs, and genetic data, a compelling new narrative emerges that challenges the legendary myth while preserving its fascinating nature.

Prominent marine biologists suggest that “Old Tom” was not a single, immortal killer whale that hunted alongside humans for nearly a century. Instead, it is highly probable that the name “Old Tom” was applied to a succession of different male orcas with similar physical traits or markings that visited Twofold Bay across multiple decades. Because wild orcas within the same pod or ecotype often share family resemblances and hunting routes, human observers across three generations of whalers likely mistook successive generations of male orcas for the same iconic individual. This “multi-individual” reality seamlessly resolves the impossible 90-year lifespan anomaly.

Furthermore, the evidence strongly suggests that the specific animal that washed ashore in 1930 was not the mammal-hunting, whale-herding Old Tom at all. Instead, it appears to have been an individual belonging to the flat-toothed, shark-eating ecotype originating from New Zealand or sub-Antarctic waters.

This mystery individual likely entered Twofold Bay, succumbed to severe oral abscesses caused by a lifetime of eating abrasive shark skin, and died of starvation on the shore. Local residents, eager to preserve their town’s famous legend and secure a historical artifact, identified the deceased animal as their beloved Old Tom, artificially lengthening the skeleton with spacers to match the famous whale’s reported dimensions.

An Enduring Legacy

The scientific re-evaluation of Old Tom does not diminish the profound cultural or historical significance of Twofold Bay. Rather, it enriches our understanding of the delicate, intricate relationships between humans, marine ecosystems, and one of the ocean’s most intelligent species.

The historical reality of the First Australians collaborating with wild apex predators for thousands of years remains one of the most remarkable documented examples of interspecies cooperation in human history. It highlights a time when human communities understood ocean dynamics deeply enough to share harvests with wild animals under a shared code of respect.

Today, the skeleton of the mystery orca still hangs inside the Eden Killer Whale Museum, serving as a silent guardian of Twofold Bay’s past. Whether viewed as the preserved remains of a legendary whale hunter or as a representative of a rare, nomadic shark-eating ecotype, the story of Old Tom continues to captivate the imagination. It stands as an enduring testament to the mysteries that still lie beneath the surface of our oceans—reminding us that nature’s true stories are often far more mysterious than the legends we build around them.
