Lolita, beloved killer whale who had been in captivity, has died, Miami Seaquarium says

MIAMI -- Lolita, the killer orca whale who has been in captivity for at least five decades, has died as officials were preparing to send her back to her home waters, the Miami Seaquarium said Friday in a social media post.

The attraction said Toki, who is also known by her Native American name of Tokitae, or "Toki," had been showing "serious signs of discomfort" over the past two days before she died sometime Friday afternoon.

In a Facebook post, the Miami Seaquarium said she died from what was believed to be a renal condition.
