Researchers in western Canada captured rare footage of a wild wolf hauling a crab trap out of deep water. The wolf pulled in the buoy, dragged the line to shore and chewed through the trap to reach the bait. Scientists say this may be the first known example of tool use in wild wolves. The discovery came after traps set to control invasive crabs kept mysteriously appearing on shore. Cameras later revealed a single female wolf performing the entire sequence. #canada #wildlife #science #wolves #re
