PHOTOS: When Animals Attack

Claudia Vollhardt hugs a killer whale at Loro Parque Zoo in Puerto de la Cruz, on the Spanish Canary Island of Tenerife, in this file photo. A killer whale bit and dragged Vollhardt underwater repeatedly during training on Oct. 6, 2007, before releasing her with a badly bruised chest and broken arm. A park spokeswoman said it was an accident and not an attack. (Loro Parque/AP Photo)
