Close San Antonio Sea World


Target: Ivy Taylor, Mayor of San Antonio

Goal: Revoke San Antonio Sea World’s business license after three large mammals in its captivity died in a three-month span.

Dart, a 12-year-old Pacific white-sided dolphin, died in captivity in Sea World San Antonio last weekend after fighting a month-long illness. This makes the third large sea mammal to die in Sea World’s captivity in the past three months. This high rate of animal mortality demonstrates that these animals are not kept in appropriate living conditions. Sea World San Antonio should not be allowed to keep animals in captivity if they cannot provide the living conditions required by these innocent creatures.

Prior to Dart, Unna, an orca, died in captivity in the same park. Unna was suffering from a host of problems, including an infection for which she was being given antibiotics, a fungus, and a systemic bacterial infection. In the end, the bacterial infection was the final cause of death, but Unna’s system had already been compromised by the other issues. Also, Stella, a beluga whale, died in the end of November as a result of gastrointestinal problems.

Furthermore, one of Dart’s Pacific white-sided dolphin companions is also sick. Betty, the ailing dolphin, is being monitored. Dart’s symptoms were documented by Sea World staff, but the actual cause of death is still unknown. Sea World staff won’t receive the results of the autopsy for another six weeks, which may be too late for Betty considering the fact that Dart died about a month after showing the first symptoms.

In order to protect Betty, the three other Pacific white-sided dolphins, and all the innocent animals at Sea World, they need to be in proper living conditions where they are not susceptible to the alleged fungus, bacterial infection, and other dangers of the enclosures of Sea World San Antonio. Sign the petition below to urge the Mayor of San Antonio to revoke Sea World San Antonio’s business license in order to prevent more unnecessary deaths of these vulnerable animals.


Dear Mayor Taylor,

Three animals in Sea World’s captivity have recently died: Dart, a Pacific white-sided dolphin; Unna, an orca; and Stella, a beluga. These animals died of seemingly unconnected ailments, which include gastrointestinal problems, an infection, a fungus, and another systemic bacterial infection. Sea World San Antonio is clearly incapable of providing safe and healthy living conditions for these innocent animals.

The three animals that have recently died in captivity in Sea World San Antonio are not the only animals to have died in the past year. Furthermore, Sea World has documented ailments of more animals, including another Pacific white-sided dolphin. If Betty’s illness has the same trajectory as Dart’s, results of Dart’s necropsy won’t prevent Betty’s death since Dart died within a month and the necropsy results will take around six weeks.

I am urging you to revoke Sea World San Antonio’s business license due to the fact that the large animals kept in captivity are not in suitable conditions to protect their fragile lives. Please take actions to enforce policies that protect these vulnerable animals from preventable mortality.

    I just watched blackfish and its really a sad thing to pull a baby from its mother and to not let them to have enough space so they don’t attack each other or feed them enough although captivity is wrong unless only for saving from extinction I think these trainers really do care and love these creatures but to jail and animal even in solitary confinement is sad and I’m sure that’s why tragedy happens
