Carl Akeley, considered the father of modern taxidermy, was attacked by this leopard he poses with.
The leopard latched on to Akeley’s left hand, chomping down with all its might, and kicking at him with its back legs like a rabid 80-pound feral housecat intent on brutally mutilating him beyond recognition and burying his body in the back yard. When his attempts to pull his hand out of the leopards’ jaws only made the creature bite down harder, Akeley, locked in a life or death fistfight with one of the most perfect predators nature ever created, did one of the most insane things ever – he punched his fist further into the leopard’s mouth.
Yes, you are reading that correctly. Carl Akeley, noted philanthropist and respected wildlife conservationist, punched a fucking leopard in the esophagus from the inside. The leopard gagged, Akeley pulled his hand out, and then he took the thing, bodyslammed it to the ground, and jumped on it with both knees, crushing it to death. Akeley, bleeding profusely from horrific wounds on both hands, clawed to shit, still recovering from a recent battle with malaria, and barely able to stand, then picked up the leopard (despite a shattered hand), threw it over his shoulder, walked back to camp with it, and taxidermized it for a museum exhibit
