Looking like stars of a shampoo commercial, muskoxen males butt heads to show off who’s boss: Wild Canadian Weather

In a show of dominance, males charge head-on at each other with the force of two colliding cars.

Muskoxen spend much of the summer months feeding on native plants. They have put on an average of 40 kilograms since winter and now, they're sporting a thick and luxurious coat. 

They are in peak form and the constant Arctic sunlight has triggered the release of testosterone. It's time to find a mate, but first they have to demonstrate who's the strongest in the herd.

During the rut, male muskoxen charge head-on at each other with the force of two cars, colliding at 50 kilometres an hour. Their horns and skull bones are 17 cm thick, protecting the brain during impact. The male with the winning stuff gets to pass his genes onto the next generation.
