JAW-DROPPING pictures of a bear cub delivering a left uppercut punch directly into the face of his sibling has been captured by an astonished nature photographer. Pictures show the force of the blow by the sand that sprayed into the air when contract was made – as well as the stunned look on the unfortunate cub as it tried to recover from a punch that looked strong enough to knock out a grown man. The pair of scrapping brown bears were caught with their dukes up in Alaska’s Lake Clark National Park by tour leader Marc Latremouille (47) from Ottawa, Canada. His other pictures show the siblings peacefully curled up with their mother after they had made peace – as well as shots of mum hunting for food in a nearby river.
