This is so unfortunate, especially because despite their name, they're generally not a threat to humans.
A trainer at the SeaWorld in Orlando, FL was killed by an Orca Whale today.
Thankfully, the incident was not during a performance.
Our thoughts are with the friends and family of those involved.
UPDATE: The Los Angeles Times is providing more details about the incident, including eye witness accounts from park guests. Apparently, the accident DID happen in front of an audience.
According to the source, an unidentified female employee was grabbed by one of the whales at the start of a show.
Theme park guest Victoria Biniak said the whale came up from the water and grabbed the woman and began "thrashing her around pretty good."
She described the scene as terribly "violent" as the whale "took off really fast in the tank, and then he came back, shot up in the air, grabbed the trainer by the waist and started thrashing around, and one of her shoes flew off."
That was when the audience was immediately evacuated and the rest of the show was cancelled.
The poor woman! Such a terrible tragedy!
