Dramatic footage shows a SeaWorld trainer being dragged underwater by two large killer whales.
Tamarie Tollison let out a "blood-curdling" scream as one of a pair of 6,000lb (2,721kg) orcas - named Orkid and Splash - pounced in front of onlookers.
The 28-year-old can be seen on the edge of the tank with her foot dangling in the water at the famous waterpark in San Diego, California.
