Two sun bears look like professional wrestlers as they take it in turns to pin each other to the ground. The playful Malayan Sun Bears - named after a golden yellow patch on their chest - grappled under a tree before rolling around on the floor at Zoo Miami in Florida, United States. Photographer Adrian Tavano said: “The fight lasted for about five minutes. They were an even match but the one with the lighter fur won in my opinion.” Did someone say ‘bear knuckle fighting’?
