SAN DIEGO (CBS 8) - SeaWorld San Diego confirms one of its orcas is pregnant but some critics don't see that as good news.
Ultrasounds done by two vets Monday show Kalia is expecting. But the news could spark more heated debate. SeaWorld has been locked in controversy since the release of "Blackfish" that's critical of orcas kept in captivity.
Kalia's calf is due in December.
SeaWorld says it's not clear if it's a natural pregnancy or the result of artificial insemination.
