SeaWorld announced Monday that Kayla, a 30-year-old female killer whale, has died.
The exact cause of the orca’s death will not be known until the results of a post-mortem examination are complete, which may take several weeks, SeaWorld said.
SeaWorld said Kayla began showing signs of discomfort on Saturday afternoon. Her veterinarians immediately began treatment based on a physical examination. Her condition worsened on Sunday.
SeaWorld ended its orca breeding program in March of 2016.
