Spinner dolphins (Stenella longirostris) are a small, social species of dolphin known for their acrobatic displays and distinctive spinning behaviour. They have slender bodies and long beaks and are generally grey with a darker dorsal side and a lighter belly. Some populations exhibit a distinctive stripe pattern along their sides.

Named for their acrobatic spins, they can leap out of the water and spin multiple times around their longitudinal axis before re-entering the water. They are highly social and often found in groups ranging from a few individuals to several hundred. This species inhabits tropical and subtropical oceans worldwide.
