This is heartbreaking news.
Last spring, SeaWorld announced that it would no longer breed orcas. At the time, there was one pregnant whale, named Takara.
Three months ago, Takara gave birth to what would be the final whale born in captivity.
This week the park announced that the baby, Kyara, has died. The probable cause was pneumonia, but a post mortem exam to find the cause of death will be conducted.
