Dolphin Calf Conceived Through Sperm-Sexing

Discovery Cove in Orlando recently welcomed a female Atlantic bottlenose dolphin to its brood — and there was no question that this new addition would be a little girl.

The calf was conceived through "sperm-sexing," which means researchers separated sperm carrying a female-producing X chromosome from sperm carrying a male-producing Y chromosome. This is the world's fifteenth calf conceived through sperm-sexing, and the first for Discovery Cove.

According to the media release, "Scientists at the SeaWorld and Busch Gardens Reproductive Research Center in San Diego, Calif., pioneered the ability to preferentially produce female or male dolphin offspring though sperm-sexing and artificial insemination."

The new dolphin weighed 35 pounds and measured 3 feet long when she was born on Nov. 30. The park says she's developing well and continuing to nurse and bond with her mom.
