SeaWorld Saddened to Announce Passing of Pacific White-Sided Dolphin, Dart

We’re saddened to announce the loss of a member of the SeaWorld family. Dart, a 12-year-old Pacific white-sided dolphin, has passed away. While the exact cause of death has not yet been determined, Dart had been monitored for health-related issues for about a month and was under constant veterinary care. A full necropsy will be conducted to determine the exact cause of death.

Dart was with two of his dolphin companions (Betty and Hailey), as well as his caretakers, when he died. Like many dolphins, Dart was high-energy, extremely playful, enjoyed participating in shows and interacting with his trainers. He had been a member of the SeaWorld San Antonio family since his birth at the park in September 2003, and he will be missed by the entire SeaWorld family. The SeaWorld Veterinary and Animal Care teams are also treating one of Dart’s older companions, a 37-year-old Pacific white-sided dolphin named Betty. Betty is the oldest of the Pacific white-sided dolphins at the park, and has been a member of the SeaWorld San Antonio family for more than 20 years. She is currently under 24-hour veterinary care for indications of inflammation or a possible infection. The SeaWorld team will continue to work tirelessly as they monitor Betty around the clock to provide essential care and treatment. Be sure to check for the latest updates. According to the National Marine Mammal Laboratory and the National Oceanic and Atmospheric Administration, no one really knows the average lifespan of a Pacific white-sided dolphin. However, that lifespan is believed to be anywhere between 36 and 40 years. It has been a difficult time for our San Antonio team, with several other recent deaths. While there are no apparent connections between these deaths, our veterinarians will be conducting a thorough review of all the cases as they work through the post-mortem examination process.
