Wolf Stealing Underwater Crab Traps Caught On Camera For The First Time
Wolf Stealing Underwater Crab Traps Caught On Camera For The First Time
Footage of a hungry wolf performing a complex sequence of behaviors on the coast of British Columbia could potentially mark the first case of tool use in wild canids.
The wolf swam into deep water to retrieve a floating buoy attached to a submerged crab trap. It couldn’t see the crab trap, but seemed to know the trap was there and how the human tool worked — once back on shore, the wolf began to reel in the line that led to the trap, scientists explained in a new research paper. Finally, when the trap emerged from the water, the wolf broke it open and devoured the bait inside.

The bait-snatching wolf lives within the Indigenous Haíɫzaqv Nation Territory on the central coast of British Columbia. These wolves spend a lot of time on the coast, with many relying on the sea for their food, according to theHaíɫzaqv Wolf and Biodiversity Projectwhich was responsible for the new research and which Artelle helps coordinate.
The new behavior was spotted because Haíɫzaqv Guardians, Indigenous people who conduct research and monitoring on behalf of their nation and the project, kept finding their crab traps damaged by an unknown predator. The crab traps are part of an attempt to eradicate invasive European green crabs (Carcinus maenas)which outcompete native crabs and generallydisrupt Canada’s marine ecosystemsso it’s important for the traps to remain intact.
Initially, it was suspected that seals, sea lions or otters may have been responsible for the damage. A lot of the traps are placed in deep water and don’t get exposed even at low tide, so it seemed likely that the culprit was a marine animal. However, within a day of the researchers deploying camera traps in May 2024 in attempts to identify the culprit, the wolf was caught red-pawed.

Wolves have long had a reputation for being smart, but this footage could be the best example yet of their cognitive prowess, the researchers said.
“We realized this was important on the first watching,” Artelle said. “Folks who know wolves well have always recognized how intelligent they are, but here is a video that really speaks for itself, that really highlights this clever behaviour, and shows us another aspect of the kinds of behaviours they can exhibit that we had not seen before.”

The wolf’s seemingly advanced intellect might not come as a surprise to owners of their domesticated pet cousins. Sophisticated behavior is well documented indogs(A familiar wolf dog), helped by the fact that we spend so much time with them. Researchers have even compared some dog behaviors, like learning the meaning ofhuman wordsandgesturesto those of our famously quick-witted relatives,chimpanzees(Pan troglodytes), according to the study.
Researchers have also considered that dogs may be tool users, evidenced by behaviors such as
to (then jump on to in order to) access food. The same is potentially true for dingos, which have similarly beenobserved manipulating furniturein captivity. However, the authors couldn’t find any reported tool use by a canid (member of the dog and wolf family) in the wild, which could make the wolf’s clever feat the first case of wolf tool use captured on camera.
Tool use was once considered a unique trait of human intelligence. However, scientists have steadily dismantled this idea by documenting various nonhuman animals —including chimpanzees,capuchin monkeysandNew Caledonian crows(Corvus moneduloides)— using tools. Of course, plenty of animals don’t need to use tools, so the behavior isnot necessarilythe most reliable indicator of superior intelligence.

Precisely what constitutes tool use is debated among scientists, which muddies the new findings. Researchers generally accept that tool use involves the manipulation of an external object to achieve a specific goal with intent. However, some behaviors, like the pulling of a rope, can be excluded from definitions when the animals aren’t deemed responsible for the rope’s orientation, according to the study.
The wolf’s use of a line to retrieve crab traps might be complex enough to be an exception to some researchers’ rope exclusion rule. The problem is that the authors of the new study aren’t sure what mechanisms are driving this newly observed behavior.
While the wolf appeared to have a sophisticated understanding of the unseen trap and its connection to the floating buoy above — potentially stemming from watching the Haíɫzaqv Guardians interact with the traps — the study doesn’t rule out that the animals used a much simpler cognitive process: trial and error.
The camera traps, which are now a permanent feature in the Haíɫzaqv crab-hunting areas, have yet to capture a second incident of a wolf hauling up submerged bait. However, the researchers did retrieve some earlier clips that suggest one camera got tantalizingly close.

The camera’s footage opens with a dark wolf walking toward an exposed crab line that disappears off-screen. Once the wolf is out of shot, the line wobbles, and the next time the camera is triggered, the wolf is seen investigating the bait cups of two traps that have somehow made it to shore.
