FAQ : Is it true that a wolverine is liable to attack a bear or a human being ?
There are many stories and legends about the wolverine and it is at times difficult to separate fact from fiction. The wolverine is capable of ferocious self-defence when cornered; it will even attack a much larger animal. It has been said that it can jump onto the back of a much larger animal and kill it by biting into its neck, but the wolverine is not a natural predator; it is more adapted to scavenging.
