This is the moment a wolf showed a rival who is the boss.
These amazing photos capture a fight between two timber wolves at a wildlife park in Germany.
But there is only one winner in this battle, and that’s the bigger one with the black fur.
Its smaller rival, with grey fur, can do nothing but roll over in submission and admit defeat.
And it was probably a smart move too, as the bigger wolf left him unharmed.
The images were taken by German photographer Ingo Gerlach, 63, at Bad Mergentheim Wildlife Park in northern Bavaria.
He said: “The wolves in this park have a wonderful space for themselves.
“It’s also fantastic for photographers, as it’s possible to get down to their eye-level and take photographs with nothing blocking the view.
“In early summer, and especially before feeding, the wolves are extremely active and fights for status are common.
“But in this instance, as soon as the timber wolf bared his teeth, the grey wolf rolled onto his back and waved his tail.
“If he hadn’t yielded to the alpha male so fast then the grey wolf could have had some serious injuries.
“Instead, the hierarchy was very quickly established and the timber wolf went back to being completely relaxed, barely paying attention to the grey wolf.”
