Stella is a 15-year-old female Commerson's dolphin living at Toba Aquarium. She was born at Marinepia Matsushima Aquarium on May 27, 2001 to Tierra and Cruz. In either 2008 or 2009, the Commerson's dolphin at Nanki Shirahama Adventure World - Ri, died. As a result, Stella was traded to the park. She remained there until January 25, 2010, when she met other Commerson's dolphins yet again at Toba Aquarium as her niece, Peace, took her place at Nanki Shirahama Adventure World. Since her transfer, she has had one child named Sky.
