5 Shocking Animal Attacks Caught on Tape
Trainers and zoo patrons see animals' wild side in vivid footage.
Aug. 17, 2012— -- intro: "What happens when the world's top predator decides to go off behavior? It can get ugly real quick."
That was Dr. Jeff Ventre in an interview with "20/20." He was describing killer whales, which he trained for three years at SeaWorld, but his point -- captivity breeds aggression -- applies to many species, in water and on land.
And trainers aren't the only victims. Zoos, which we think of as places for innocent family fun, have seen their share of ugly attacks -- many caused by humans going "off behavior."

Bert Lucas, producer of "The Kachunga and the Alligator Show," rushed in to keep the gator from flipping over into what's called a death roll.
"There's no nerve damage, there was no muscle damage. Everything's working, I just got a few stitches," Beck said.
