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.

Spinner dolphins are found in tropical and subtropical waters. They inhabit open oceans, coastal areas, and sometimes bays and estuaries. They are particularly common around the Hawaiian Islands, Gulf of Mexico, Southeast Asia waters, and Indonesia.

Spinner dolphins are commonly seen in the waters around Indonesia and West Papua, particularly in regions like Raja Ampat.
