Spotted dolphins and spinner dolphins are often found living with tuna. When people started using large nets to capture tuna in the 1960s, many dolphins were killed as well. Scientists responded by sending “observers” on tuna boats to keep track of the number of dolphins killed. Scientists store samples of different parts of dolphins collected from dolphins killed by the tuna nets. In this public radio story you hear from a scientist who is studying these tissues to try to learn more about these dolphins in order to help preserve dolphin populations.
