Reproductive Biology
Understanding the reproductive biology of dolphins can help inform conservation efforts for these important species. Dolphins give birth about every 3-6 years and they invest lots of effort into raising their offspring. Multiple projects are underway to better understand the reproductive anatomy of dolphins and other marine mammals.

How do we study dolphin reproductive biology?
Researchers with the TCBDP use a variety of methods to learn about dolphin reproductive biology. We rely on specimens from stranded individuals to learn about the reproductive anatomy of marine mammals. Using sophisticated 3D printing and 3D scanning technologies, we can create 3D models of marine mammal reproductive tracts to uncover new information about their evolution.

We also partner with aquaria to collect sperm samples from dolphins in managed care to learn about dolphin sperm biology. A current study aims to examine the impact of female reproductive tract features on sperm activity in common bottlenose dolphins. The ultimate goal of this study is to improve our understanding of dolphin reproductive biology to better conserve marine mammals around the globe.
