UPDATE July 15, 2011. We estimated that Big Bertha's pregnancy will end sometime in June/July 2011 after a 13 months gestation period. We are happy to announce that Big Bertha is not pregnant anymore! She gave birth to a Manta Ray pup sometime between June 30, 2011 and July 15, 2011. We filmed her regularly and have created a movie about her pregnancy starting with courtship behavior. Check out Big Bertha's pregnancydiary here.
