Notes and Information

In 2013 SeaWorld Orlando applied for a permit to import Raisa; the permit was approved, although Raisa was never transferred to the facility, and instead was moved to Tierpark Hagenbeck two years later.

Raisa passed away from heart failure; her necropsy revealed chronic damage to her heart.
