Bottlenose dolphins are frequently spotted in the Chesapeake Bay during the summer with reports of them leaping in the air or bow riding boats. While these seems like fairly straightforward questions, for migratory animals, coming up with the answers is quite difficult. “We know very little about them,” says UMCES DolphinWatch.

One way to help determine which population the PC dolphins belong to is through what is called Photo ID. That effort grew into the Potomac-Chesapeake Dolphin Project, which today surveys the social and super-smart mammals from May through October in about 14 square miles of the Potomac. With the dolphins identified, scientists can determine where the dolphins are coming from and going to.
