Highly intelligent and social, bottlenose dolphins use signature whistles as individual names and pass tool use across generations.
§ Quick facts
§ Encyclopedia
The common bottlenose dolphin or Atlantic bottlenose dolphin is one of three species of bottlenose dolphin in the genus Tursiops. While formerly known simply as the bottlenose dolphin, this term is now applied to the genus Tursiops as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized and split out.
