Jocasta is a matriarchal figure within Unit J. She has been a mother on two occasions, having given birth to Oedipus prior to 2005, and Antigone in 2009. She appears to have welcomed yet another calf in 2021. While we have yet to confirm parentage, the little whale was documented swimming close to Jocasta during our most recent field session.

At the time of our data collection, Jocasta kept her distance from underwater researchers and seemed focused on her parental responsibilities. We able to verify her positive identify only after close inspection of our video footage.
