14. Wolverine

While we previously mentioned the smallest weasel, now we’re talking about the biggest. The wolverine (not the mutant), is another meanie in the animal kingdom, and is the largest member of the weasel family. They are extremely dangerous and aggressive creatures, capable of taking down animals that are larger, like bears for example, and without hesitation. They also don’t hibernate, so that means they can go on a killing spree all year round.
