Preterm birth

Katina (orca)
On September 26, 1985, Katina went into labor. A few hours later, she bore her first calf—a female, who was named Kalina. Although ten Orca calves had been born in captivity prior to Kalina, none of them had survived past a few weeks. This made Kalina the first Orca calf to be successfully born and raised in captivity, which made Katina the first successful mother. The success of the captive Orca breeding program began with Katina in 1985. Kalina went on to live for 25 years, before she died at SeaWorld Orlando in October 2010.
