Common bottlenose dolphins are found throughout the world in both offshore and coastal waters, including harbors, bays, gulfs, and estuaries of temperate and tropical waters. They are one of the most well-studied marine mammals in the wild. In addition, they are easy to view in the wild because they live close to shore and are distributed throughout coastal and estuarine waters. They are a highly intelligent species and use sound both for communication and to hunt for food.(NOAA Fisheries)
