The bottlenose dolphin (Tursiops truncatus) is distributed across a wide range of temperate to tropical seas worldwide, with separate coastal and offshore populations. Adults range from 1.9 to 4.3 m in length, males tending to be larger. They primarily feed on fish and cephalopods, and show diverse foraging techniques and tool use, such as striking the seabed with their tail flukes to drive out fish. Highly social, they live in small groups and sometimes form large aggregations. They demonstrate high intelligence, including advanced vocal communication and mirror self-recognition, and give birth to a single calf after about a 12-month pregnancy. As a species, they are relatively numerous and assessed as Least Concern, but bycatch, pollution, and drive fisheries are problematic threats.
