The Extreme Elks
North American Elks take mating season seriously. Bulls usually weigh in at about 300 to 350 kilograms, but during mating season they bulk up and can weigh about 500 kg. Talk about getting ripped! All that extra muscle can come in handy when they rut — the bigger the bull, the more likely it will win. Whichever male comes out on top will have up to 30 cows it can mate with. The losers? Well, they’re not kicked out of the herd entirely, but they kind of become outsiders.
