Perhaps the most problematic facet of SeaWorld's breeding program is the matching of genetically-close individuals like Nalani, a female orca at SeaWorld Orlando, who is the offspring of a 37-year-old female named Katina and her own son, a male named Taku. So Taku is both father and half brother to Nalani. Another example is Kohana, a female born at SeaWorld San Diego in 2002, who was moved to the marine park Loro Parque in Spain, where she was bred with Keto, the brother of her mother. She gave birth to Adan in 2010, but refused to raise him, so staff had to bottle-feed him.
5. SeaWorld's breeding program results in a high number of stillbirths.
Orcas are notoriously difficult breeders -- even more so in captivity. In fact, until the whale Kalina was born in September 1985, no captive-born orca was able to survive more than a few days. Before Kalina, the 10 orcas born in captivity were all stillborn. In 2010, a 21-year-old mother orca named Taima died while giving birth to a stillborn baby at SeaWorld Orlando.
