Shark dies after being shipped from New York to Los Angeles for a Kmart commercial sparking investigations from animal rights groups Animal activists are setting their sights on Kmart after a 5-foot-long white-tipped shark died following a commercial video shoot for the Sears-owned retail chain. The shark was put in an above-ground swimming pool at a home in Van Nuys, California, where the Kmart commercial was being filmed, according to PETA and the American Humane Association. The shark died on March 6 after being shipped from New York to Los Angeles. Shark death: A a 5-foot-long white-tipped shark died after it was shipped from New York to L.A. and placed in an above-ground pool for a Kmart commercial shoot Investigation: Kmart and the American Humane Association said the incident is being investigated The AHA, which approved the commercial's script and present at the time of the filming, reportedly allowed shooting to continue for about an hour after the shark began showing signs of stress. The shark was injected with adrenaline and given oxygen after it showed signs of stress, according to a statement released Thursday by the AHA. It was later taken out of the pool and transported to an aquatic compound, where it died that afternoon. "The shark appeared to be healthy upon our arrival and during filming, which involved only the animal swimming normally in a 60,000-gallon tank and exhibiting natural behaviors," the AHA's statement read. The animal was never trapped and at no point was anyone in the tank with the shark. Nothing more was required of the animal. The organization said that it has ordered an investigation into the shark's death.

"Sharks are delicate animals who, in captivity, require a highly specialized and controlled environment," PETA said in a statement. The noise and chaos of a commercial shoot is a very stressful environment for these sensitive animals. A Kmart spokesperson told the Los Angeles Times the incident is being investigated.
