Although bottlenose dolphins live off the coast throughout the United States, our research primarily focuses on stocks in the Gulf of Mexico and the Atlantic. Bottlenose dolphins are easy to view in the wild, but this also puts them at increased risk of human-related injuries and death. Bottlenose Dolphins prefer shallow, inshore waters and are commonly seen off the coasts of Hawaii and Florida. The most common and well known of the species is the bottlenose dolphin.
