In 1997, scientists strapped cameras to sperm whales to find giant squid. 7 years later, researchers finally filmed the elusive monster alive

For decades, the giant squid was known more from evidence than direct observation. Sperm whales returned from deep dives carrying strange circular scars. Those wounds suggested violent encounters with an enormous animal hiding far below the surface. Scientists knew sperm whales hunted giant squid, but almost nobody had seen the predator alive in its natural habitat.

In early 1997, researchers tried a bold experiment off New Zealand. They would let a sperm whale become their guide. The idea was simple: follow the hunter and perhaps find the giant squid. Instead, the expedition produced something more valuable than dramatic footage. It exposed how difficult deep-sea research really was and helped shape the search that eventually brought the giant squid into view.

How did Scientists try to find the giant squid?

Clyde Roper of the Smithsonian’s National Museum of Natural History led the 1997 expedition to Kaikoura Canyon. The deep underwater canyon lies close to New Zealand’s South Island. It offered researchers a promising place to investigate the relationship between sperm whales and giant squid.


The expedition used several technologies at the same time. Odyssey II, a robotic underwater vehicle associated with MIT’s Sea Grant laboratory, explored the canyon independently. Researchers also deployed Ropecam systems carrying bait and lights. These instruments were designed to attract or observe animals moving through the darkness.

The most ambitious attempt involved Crittercam. National Geographic Television built the high-sensitivity camera system to ride on a sperm whale. Researchers hoped the animal would take the camera into depths humans could barely explore.

That strategy made sense. Sperm whales regularly dive thousands of feet while hunting squid. If giant squid were nearby, the whale might naturally lead scientists toward them.

But the plan failed almost immediately. The suction-cup mounting holding Crittercam to the whale came loose. The camera separated before it could deliver the extraordinary footage researchers wanted. Meanwhile, Ropecam dropped bait into the darkness, while Odyssey II continued surveying the canyon and surrounding water.

The instruments revealed a busy deep-sea environment. Yet the giant squid remained hidden.

The failure was frustrating, but it was not meaningless. Researchers learned more about the environment and the practical problems involved in studying large animals at extreme depths. More importantly, the expedition reinforced a lesson that would follow giant squid research for years. Knowing where an animal might live is very different from actually finding it.

Why were Sperm Whales so important to the Giant squid search?

Sperm whales provided one of the strongest clues in the entire giant squid mystery. Their bodies carried physical evidence of encounters with powerful squid.

Some whales showed pale, circular scars across their heads and bodies. The marks were consistent with contact from squid suckers. Those scars became a kind of biological record, showing that sperm whales were encountering giant squid somewhere beneath the surface.

That relationship made the whale an unusual research partner. Scientists did not need to guess whether giant squid existed. They already had a predator repeatedly returning from the deep with evidence of them.

The problem was locating the prey. The giant squid lives in an environment that is almost perfectly designed for avoiding humans. Sunlight disappears with depth. Visibility becomes extremely limited. Pressure rises dramatically. Animals can move through enormous volumes of water without ever crossing the path of a camera.

Roper reportedly compared the search to birdwatching in a vast forest. The comparison captures the difficulty surprisingly well. A researcher may know the animal exists and even understand its habitat, yet still spend years waiting for a glimpse.

That is why the 1997 expedition mattered despite producing no giant squid footage. It was part of a broader shift in scientific thinking. Instead of relying mainly on dead specimens, whale scars and accidental strandings, researchers increasingly looked for ways to observe the animal alive. The technology had to become quieter, smaller and more patient.

How did a cheaper camera experiment finally find the giant squid?

Seven years after the New Zealand expedition, researchers changed the strategy. Instead of placing a camera on a sperm whale, Tsunemi Kubodera of Japan’s National Science Museum and Kyoichi Mori of the Ogasawara Whale Watching Association used a baited line.

Their 2004 expedition took place near the Ogasawara Islands, roughly 1,000 kilometres south of Tokyo. The researchers lowered bait into deep water and attached a camera that automatically photographed the area at regular intervals.

The approach lacked the drama of chasing a whale. Yet it solved an important problem. The researchers did not need to follow an animal through the darkness. They could leave the equipment in a promising location and wait. That patience paid off.

The camera captured images of a living giant squid attacking the bait. The photographs provided some of the first compelling evidence of a giant squid alive in its natural deep-sea environment.

The discovery changed the story surrounding one of the ocean’s most famous animals. The giant squid was no longer simply a creature reconstructed from tentacles, beaks, scars and damaged bodies. Scientists finally had a living animal interacting with its environment. The achievement also showed why the failed 1997 mission should not be dismissed as a scientific dead end.

Its biggest contribution was not a photograph. It was knowledge about what did not work. The giant squid could not simply be filmed by attaching a camera to its predator. Deep-sea observation required a different kind of patience. Researchers needed to understand the animal’s habitat, anticipate its behavior and build equipment capable of waiting where the animal might appear.

In that sense, the giant squid was never really defeated by a bigger machine. It was approached through better questions. The mystery also changed the way scientists think about the deep ocean. Some of Earth’s largest animals can remain almost invisible despite living beneath heavily studied waters. Their existence can be obvious through traces, predators and biological clues while direct observation remains extraordinarily difficult.

The 1997 failure therefore became part of the eventual breakthrough. Scientists went looking for the giant squid and came home without the footage they wanted. Years later, another team used a simpler idea and finally captured the animal on camera.

Sometimes, scientific progress does not arrive as a discovery. Sometimes it begins with a failed experiment that teaches researchers where not to look, how not to search and what the ocean is still keeping from view.
