4. Moose
Moose are part of the deer family, and are the largest members. But, unlike their fellow deer or stag, they are anything but friendly. Second to the hippo, moose have managed to attack more humans than any other wild animal. They are at their most aggressive when it’s mating season in the fall, which as you all know, is when they all start shacking up and making babies, because that’s when their hormones are high.
