Should animals using external objects to obtain food be officially classified as tool users?

On May 29, 2024, remote-camera footage captured a female gray wolf hauling a submerged crab trap onto a beach to retrieve the bait. This behaviour, which researchers noted in a November 2025 study, highlights an unusual adaptation among predators in coastal territories.

Why it matters

The study suggests that wolves may be learning to scavenge human-provided food sources through gradual observation of crab management activities. Scientists are now debating whether this innovative foraging technique qualifies as formal tool use.

A study published in November 2025 confirmed 2 wolves successfully hauled crab traps from the water in British Columbia. The behavior involves pulling a buoy line to drag submerged traps onto the beach to access the bait cup.

Ecology and Evolution

This peer-reviewed academic journal published the research findings regarding the observed wolf behavior in November 2025.

The details

The wolves appear to have learned this technique by either watching humans lift traps or by accessing previously damaged traps found on the shoreline. After hauling the traps, the animals work to detach the bait cup by chewing and pulling on the lines until the container is free.

Crab traps in the area began turning up damaged throughout 2023.

Cameras recorded a second wolf pulling a trap line on February 14, 2025.
A study regarding the wolf behavior was published in November 2025.

Culture Shift

The study adds new evidence to the ongoing debate over animal cognition and tool use, mirroring discussions seen in primate research. This discovery suggests that coastal predators are increasingly adapting their survival strategies to interact with human infrastructure.

This research provides insights into how wolves may interact with local commercial fishing gear in British Columbia. Residents and fishers working in these coastal regions may need to secure their equipment more effectively to prevent wildlife interference.

The takeaway

This case illustrates the high level of intelligence and adaptability wild wolves display when presented with new food sources. Observers in the region should respect the intelligence of these animals and maintain a safe distance when conducting outdoor activities.
