Tursiops aduncus (Indian Ocean Bottlenose Dolphin) is a species of mammals in the family Delphinidae. They are native to Pacific Ocean and Indian Ocean. They are diurnal carnivores. Individuals can grow to 2.7 m. They have parental care (female provides care and cooperative breeding). They rely on swimming and lift powered swimming to move around.

Definition: Self-propelled movement of an organism from one location to another through water, often by means of active fin movement.

URI: https://eol.org/schema/terms/lift_based_swimming
Definition: Hydrofoils, or fins, are used to push against the water to create a normal force to provide thrust, propelling the animal through water. The reduction of fin cross-sectional area helps to minimize drag, and therefore increase efficiency. Regardless of size of the animal, at any particular speed, maximum possible lift is proportional to (wing area) x (speed)<sup>2</sup>. Dolphins and whales have large, horizontal caudal hydrofoils, while many fish and sharks have vertical caudal hydrofoils.
