In 2004 SeaWorld brought in another wild-caught Commerson's from Germany. At 30 years old, Jogi was the only survivor of a group of 10 Commerson's taken from the wild, and had survived decades in captivity. Once at SeaWorld, he died within months.
The company tried to breed the dwindling wild-caught population, but artificial insemination didn't work well "because when they'd go to jack them off they'd get urine and semen samples, and the urine would cancel out the semen," Fischbeck said. The natural births were equally disastrous. Some were stillborn; others lived just a few years.
By 2008, they had seven left, Fischbeck said. SeaWorld sent four males to their Aquatica park in Florida; in 2014, two of them died within weeks of each other.
"In less than 30 years they've killed off 20 Commerson's dolphins," Fischbeck said. "The average lifespan at SeaWorld is 8 years."
By the end of Fischbeck's time at SeaWorld San Diego, Betsy had only two companions left: Juan, the only other survivor of the 12 wild-caught Commerson's, and Ringer, Juan's daughter.
