ORANGE COUNTY, Fla. — SeaWorld is running tests to find out what killed one of its whales.
An 18-year-old whale named Jozu died on Monday.
SeaWorld officials said it had a history of chronic health problems, but they're trying to figure out exactly what caused her death.
She was known as a false killer whale that shares characteristics but is different than the Orca killer whale.
Jozu was born at SeaWorld Orlando in 1994.
SeaWorld will do a necropsy but won't get the results for 6 to 8 weeks.
