SeaWorld’s Takara No Longer Considered Pregnant
At the risk of over-exciting all my skeptics, who think I pull SeaWorld orca pregnancies out of my ass, I have been getting word that SeaWorld Texas’ Takara is not pregnant. Takara was one of a number of SeaWorld pregnancies that I wrote about last November. All seemed normal, and SeaWorld considered Takara to be pregnant, but in March her progesterone levels dropped below a level consistent with pregnancy. An investigatory sonogram did not reveal a fetus, but it was not clear whether she had lost the fetus (though she had not passed one) or simply had experienced a false pregnancy.
The failure of Takara’s pregnancy raised a question about the sperm of Kshamenk, the male from Argentina’s Mundo Marino, which had been used in Artificial Insemination (AI) procedures on both Takara and Kasatka. Kshamenk’s sperm is one way for SeaWorld’s captive breeding program to get beyond a preponderance of Tilikum genes, so it is important to the future of orca breeding at SeaWorld. But Kasatka’s pregnancy is progressing, with a fetus visible on sonograms, so Kshamenk’s sperm is at least viable.
So Takara will not be giving birth along with Kasatka and Kohana. However, she seems healthy despite the false or failed pregnancy, and SeaWorld plans to try and inseminate her again by mid-summer. Not sure whether they will use Kshamenk’s sperm again. But SeaWorld also has an AI and sperm collection arrangement with Marineland Antibes in France, which used sperm from SeaWorld California’s Ulises to impregnate their younger female, Wikie. That led to the birth of a calf called Moana last year. Marineland Antibes has two males, Valentin and Inouk, who are sexually mature and presumably could also be used as sperm donors for SeaWorld’s breeding program.
SeaWorld Florida also has plans to AI Kayla sometime soon (in March I mentioned she was next on the AI list), though apparently she does not cycle normally, so the timing is a bit tricky.
That’s all the orca pregnancy news I have for the moment. So let the skeptics have at it…
