Cadborosaurus

The Horse-Headed Serpent of Cadboro Bay

“A horse-headed serpent rides the Pacific swells off Vancouver Island, glimpsed and gone before the camera lifts.”

Cadborosaurus — Caddy, to the British Columbia press that adopted it — is the sea serpent of the province's Pacific coast, reported for two centuries from Cadboro Bay, Saanich Inlet, and waters far beyond. The composite portrait from some three hundred sightings is remarkably stable: a horse- or camel-like head on a long neck, a serpentine body showing vertical coils or humps in series, small front flippers, and a tail ending in hind flippers or a fused, fan-like fluke.

The name is newsroom Latin — Cadboro Bay plus 'saurus' — and the nickname Caddy came from Victoria journalist Archie Wills. But the creature is older than its christening: the coastal First Nations knew it long before the newspapers, as hiyitl'iik to the Manhousat, t'chain-ko to the Sechelt, and numkse lee kwala to the K'omoks. Among marine cryptids, Caddy is unusual for having a carcass, a scientific name, and a formal species description — every one of them contested.

The Legend

Sea-serpent traditions run deep on this coast. Generations before the Victoria papers took up the story, the Manhousat people spoke of hiyitl'iik, the Sechelt of t'chain-ko, and the K'omoks of numkse lee kwala — named beings in the same waters that settlers would later scan for Caddy. When sightings multiplied in the twentieth century, the reports slotted into a seascape that already had room for a great serpent.

The classic Caddy is a creature built for speed rather than bulk: a long neck carrying a head likened to a horse or a camel, humps or coils breaking the surface in tandem, flippers fore and aft. Witnesses put its length anywhere from five to fifteen metres. Reports concentrate around Cadboro Bay and Saanich Inlet near Victoria, though claimed sightings extend down the Pacific coast as far as San Francisco Bay.

Documented Sightings

The case's strangest exhibit surfaced in July 1937 at the Naden Harbour whaling station on Langara Island, Haida Gwaii: a carcass nearly four metres long drawn from the stomach of a sperm whale — long-bodied, with what looked like a camel-like head and a fluked tail. The station's first-aid officer, G. V. Boorman, photographed it. A sample went to the BC Provincial Museum, where director Francis Kermode wrote it off as a fetal baleen whale, and the remains themselves were then lost to science entirely.

The photographs resurfaced in the Provincial Archives in Victoria in 1992, found by researchers Paul LeBlond and Edward Bousfield — who took the extraordinary step of formally naming the animal Cadborosaurus willsi in 1995, designating Boorman's pictures as the holotype. Zoologist Darren Naish counters that the identification rests on pareidolia, that the carcass reads plausibly as a basking shark or sturgeon, and that faked Caddy carcasses were being produced in British Columbia in that very era.

The Lore

Caddy sits at the respectable end of cryptozoology: a phenomenon with named scientists, archived photographs, and a species description in the peer-reviewed record, even if critics judged the science bad. The dispute is instructive — LeBlond and Bousfield assumed that hundreds of conflicting eyewitness accounts described a single animal, where sceptics see a catalogue of different animals and floating objects stitched into one serpent.

Whatever the Naden Harbour carcass was, its loss guaranteed the legend's survival: no specimen, no closure. Caddy endures as the Pacific Northwest's signature sea mystery, its sightings file still open after two centuries, and its Indigenous names stand as a reminder that the question of what swims these inlets is far older than the culture that gave it a Latin binomial.

Field Notes

✦ Coastal First Nations traditions — hiyitl'iik, t'chain-ko, numkse lee kwala — long predate the Caddy reports.
✦ The famous 1937 Naden Harbour carcass, taken from a sperm whale's stomach, was lost before proper study.
✦ Descriptions favour a fast, flexible, undulating swimmer rather than a bulky whale-like body.
✦ LeBlond and Bousfield named it Cadborosaurus willsi in 1995, with the 1937 photographs as holotype.
✦ More than 300 claimed sightings over two centuries cluster near Cadboro Bay and Saanich Inlet.
