* Size Disparity: Wolverines are much smaller than bears, typically weighing around 30-60 pounds, while bears can range from 100 to 1500 pounds.
* Opportunistic Predators: Wolverines are incredibly aggressive and fearless for their size. They are known to scavenge on large carcasses, including bears, and have been observed eating cubs.
* Survival Tactics: A wolverine's primary strategy for taking down prey larger than itself is to attack while the bear is vulnerable, such as during hibernation or when it is injured or weakened.
* Rare Occurrences: Because of the size difference and the risk involved, wolverines rarely prey on healthy adult bears. They are more likely to scavenge on bear carcasses or prey on cubs.
So, while a wolverine eating a bear is possible, it is not a common occurrence. It's more likely they'll go after easier prey like smaller mammals, carrion, and even fish.
