When do female dolphins begin to have babies?

Mar 16, 2011 No comments By Blair Irvine

 

Dolphins may first give birth when they are 6-13 years old, but most often they are about 8 years old.  The baby is born tail-first after a 12-month gestation period. Most babies are born in the Spring – Summer months. Two dolphins continued to have babies until they were 48 years of age.

About the author

I manage the SDRP website, serve as President of the Dolphin Biology Research Institute, and otherwise volunteer as needed. I started the SDRP in 1970 with then High School student Randy Wells, and I led the research through the 70’s. Randy took over in the early 80s when I changed careers. Since then, my non-dolphin interests mostly have been in the area of human behavioral health. With NIH support, much of my research has involved Internet interventions and training programs. My graduate degrees are in Zoology (MS), Exercise Physiology (MAPE), and Health Education (PhD).
