About the Species
Spinner dolphins are best known for their above-water displays of leaping and spinning several times. A single spinning leap can include as many as four body revolutions. Spinner dolphins are found throughout the world's tropical and subtropical oceans.
Spinner dolphins, like all marine mammals, are protected under the Marine Mammal Protection Act. The Eastern stock in the Eastern Tropical Pacific Ocean is listed as depleted under the MMPA.
NOAA Fisheries is committed to conserving and protecting spinner dolphins. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.

Dolphin-Safe/Tuna Tracking and Verification Program
Dolphins, like other marine mammals, may become bycatch in fisheries. Some species of tuna are known to aggregate beneath schools of certain dolphin stocks. In some parts of the world, this close association led to the fishing practice of encircling a dolphin school to capture the tuna concentrated below. The Dolphin Protection Consumer Information Act established a national tuna tracking program to ensure that tuna imported into the United States meets certain requirements to ensure the safety of dolphins during tuna fishing operations.
