Haruka was an estimated 15-20 year old female Pacific bottlenose dolphin who was captured on October 28th of 2006 and placed at Taiji Whale Museum, she would later on pass from multiple organ failure on April 4th of 2013.
This dolphin was considered very special due to the fact that she was born with two vestigial hind limbs that were about 15cm on either side of her genital slit, she was given the name Haruka through a visitor poll, as the name means "of the past" as this was a characteristic of the ancestors of modern cetaceans.
Haruka was seen as a big opportunity to research and learn about the evolution of cetaceans, there were also attempts to have her mate and to produce offspring but nothing ever came of it.
