Talking to dolphins
STEPHANIE Henderson and Morgan Mingle have discovered that Jet the baby
dolphin at the Pet Porpoise Pool is disciplined regularly.

hydrophones and six cameras.
The project is an ongoing collaboration with Prof. Jesse Purdy, a comparative
psychologist with Southwestern and Dr Anna Brooks an SCU psychology
