It's a girl!

Published March 18, 2010

After a week of close observations of the new dolphin calf, our trainers have confirmed that it’s a girl!

Wondering how they can distinguish a male from a female? Even though male and female genitalia of dolphins are internal, it’s fairly easy to determine the sex externally. Males have two separate slits, or grooves on their underside. They lie in line with each other in a way that resemble an exclamation point. Females only have one slit or groove and a mammary slit on either side, which produce milk when they are reproductively mature. A female’s underside resembles more of a division sign.

The trainers and animal care staff have had little interaction with the calf since birth. She is particularly strong, and a fast swimmer so it took about a week for them to get a good look at her underside through the observation windows.

She continues to swim with her mom, Jade, and Shiloh, and seems to be adjusting well to her surroundings. The Amphitheater has re-opened and visitors are invited in to enjoy quiet dolphin shows, and may catch a glimpse of the baby as she surfaces with her mother for a breath of air.
