A 6-year-old female orca named Amaya died unexpectedly at SeaWorld San Diego on Thursday. The reason was not immediately known. “Amaya began showing signs of illness on August 18, and animal care specialists and veterinarians began treating her immediately. Despite her care team’s efforts, Amaya’s condition continued to decline rapidly. Her death was sudden and unexpected,” aquarium and theme park said. Amaya was the youngest of 10 whales at the San Diego park and spent time with her mother Kalia and father Ulises. SeaWorld said the specialists who cared for Amaya were heartbroken. “This is a very difficult time for those who knew and loved Amaya. She inspired millions of guests to appreciate and learn more about this amazing species.
