On September 26, 1985, Katina gave birth to the first successful calf born in captivity. The calf was named Kalina and she became known as the Original Baby Shamu. Kalina went on to have 4 calves of her own: Keet, Keto, Tuar and Skyla. Katina became a great great grandmother when Kalia gave birth to her first calf, Amaya, on December 2, 2014. Kalia is Keet's first calf.
Katina gave birth to her 2nd calf, Katerina, on November 4, 1988. Katerina passed away on May 5, 1999. Her 3rd calf was her first male and he was named Taku. He was born on September 9, 1993. He sired two calves, Truaand Nalani. He passed away on October 17, 2007.
She gave birth to her 4th calf, Unna, on December 27, 1996. Taima assisted Katina through the delivery and after. Unna passed away on December 21, 2015. Ikaika was her 5th calf, born on August 25, 2002. This pregnancy was one of four featuring orcas on the Animal Planet show That's My Baby.
Her 6th calf was Nalani, born on September 18, 2006. Nalani was the first inbred calf to be born in captivity. Her father was Taku, who is also her brother. Katina and Taku were very close. Nalani was Taku's second calf. Despite the inbreeding, Nalani has not shown any signs of falling behind and is a very smart and playful whale. She often helps Katina care for her younger brother Makaio.
Makaio was Katina's 7th calf, born on October 9, 2010. He was born just days after Katina's oldest calf, Kalina, passed away. A poll was held for the naming of her calf. Makaio was chosen, which means gift of God in Hawaiian.
Katina is a very loving whale. She did waterworks before they were stopped in 2010. She has never shown any aggression to her trainers and has a very close bond with them. Although she is the dominant whale, she is usually relaxed around the other orcas, unless she needs put them in their place or discipline the young. She is usually grouped with Nalani and Makaio, though she does spend time with Kayla and Trua. She hasn't been spending as much time with Malia lately. In mid 2016, she and Makaio started being grouped with Tilikum off and on. She and Tilikum used to perform together along with Taku and Unna when they were young. She is a very loving mother and shows this not only to her calves, but the many other calves who have been born at the park. She has been a surrogate mother to several calves and will also babysit other orca's calves.
Katina is a very energetic whale. When asked to do a behavior she often puts all her effort into them. She is by far the highest jumper at Orlando. She knows many behaviors for drywork and knew many for waterworks as well.
