Maddox Derkosh, a two year old boy, was mauled to death by African painted dogs at the Pittsburg Zoo in 2012. His mother admitted to holding him out above an observation deck to get a better view of the dogs, before he suddenly lurched forward and fell into the enclosure. An autopsy confirmed he didn't die from the fall, but rather from being savagely ripped apart by the wild dogs.

In 2011, 19 year old Olga Moskalyova called her mother from the woods in Eastern Siberia as she was being attacked by a brown bear and her three cubs. Tatiana, her mother, listened in distress while Olga was eaten alive by the bears. At first she thought it was a joke, but she soon heard the sounds of the bears growling and chewing. Tatiana contacted nearby police, who rushed to the river where the attack was taking place. Not only did Olga die in the attack, but when authorities arrived, her father Igor's remains were still being devoured nearby.

Tilikum, a killer whale at SeaWorld, struck for the third time in 2010 when he grabbed the ponytail of his trainer, Dawn Brancheau, and dragged her to the bottom of the pool. Tilikum's violent thrashing fractured Brancheau's jaw, part of her vertebrae, several ribs, and dislocated her elbow. She did not survive the attack. In 1991, trainer Keltie Lee Byrne fell into the enclosure holding Tilikum and two other whales at Sealand in Canada. It was found that the whales prevented her from escaping the enclosure, and her death was ruled an accident. Once again after being transferred to SeaWorld in 1999, the body of Daniel Dukes was found naked and draped over Tilikum's body in the enclosure. It was reported that Dukes got past security and stayed at the park after it had closed. He then either jumped or fell into Tilikum's pool.

12 year old Brian Jeffrey Griffin was swimming in a Florida river when his friends suddenly began screaming for him to get out of the water. His two friends saw the estimated 11 foot alligator swimming towards Griffin, but it was too late. It grabbed the boy and retreated beneath the surface of the water.

In 2003 a 7 year old white tiger named Montecore attacked performer Roy Horn of Siegfried and Roy during a performance on the Las Vegas strip. The attack left him with a brain injury that led to a stroke, and as a result Roy is partially paralyzed. After the brain injury, the tiger grabbed Roy in what he describes as a manner in which a tiger would pick up her cub, and dragged him off to the side of the stage. It is then that one of the tiger's teeth knicked an artery in Roy's neck, causing massive blood loss. To this day, he does not blame the tiger for the attack and Montecore has since passed away from illnesses at age 17.

Andrew Oberle, a 26 year old graduate student, was standing in a restricted area of a chimpanzee enclosure for which he did not have clearance when he was pulled under an electrified fence by two male chimpanzees. The incident in 2012 left Oberle fighting for his life while they bit him and dragged him half a mile in an act of territorial defence.

After 22 surgeries and impossible odds, Oberle made a full recovery.

In 2012 a zookeeper whose identity was kept hidden was killed by the very pack of wolves she raised at the Kolmarden Zoo in Sweden. The keeper reportedly followed standard procedure and notified a coworker before entering the wolf enclosure, which she had been doing since they were pups. When other employees couldn't reach her over her radio, they went to check on her and found her already dead inside the enclosure. Officials had difficulty safely recovering her remains. The zoo staff were forced to make a human chain to usher the wolves away from her remains, and they eventually had to be given sedatives so that the ambulance workers could enter to recover what was left of the zookeeper's body.

Jaren Hare and Charles Darnell were both sentenced to 12 years in prison in 2009 for manslaughter and child neglect when their 8 and a half foot albino burmese python escaped its enclosure and entered their toddler's room in the middle of the night.

Christmas of 2007, a female siberian tiger was killed in a hail of gunfire after killing 17 year old Carlos Sousa Jr. and injuring two of his friends. Claw marks were found at the top wall of its enclosure at the San Francisco Zoo, indicating that the tiger was able to get enough leverage to leap up from the dry moat at the bottom and pull itself out. Zoo officials claim the boy must have really agitated the tiger, as she walked right past easily accessible hogs that would make a great food source, and instead followed Sousa's trail.

World famous Steve Irwin died in 2006 when his heart was pierced by the barb of a stingray during the filming of an underwater documentary.

Phil Bronstein suffered a komodo dragon attack while at the L.A. Zoo with his wife, actress Sharon Stone. Shortly before the attack, Bronstein was advised to remove his white sneakers, as they resembled the white rats that the dragons were fed.

Despite the killing of his wife and baby-to-be, Greg maintains that pitbulls are harmless dogs and he forgives Gunner for the incident.
