Spinner dolphins are probably the most frequently encountered cetacean in nearshore waters of the Pacific Islands Region. Spinner dolphins can feed at any time of the day. Exclusive Economic Zone (including those at French Frigate Shoals) are part of the Pelagic stock. Research such as photo-identification studies. Passive acoustic monitoring using towed hydrophone arrays and other tools. Partial (time-area based) closures for certain spinner dolphin resting habitats, Regulation of human behavior while in NOAA Fisheries-identified spinner dolphin resting areas, Complete closure of all known spinner dolphin resting areas in the Main Hawaiian Islands. Never approach or try to save an injured or entangled animal yourself—it can be dangerous to both the animal and you. Results of the cooperative studies will help managers assess and resolve issues with human-dolphin interactions, such as impacts on spinner dolphins arising from "swim-with-dolphins" tourism operations.

This playful animal is the most frequently seen cetacean in some tropical open seas. Currently, Spinner dolphins are classified as Data Deficient (DD) on the IUCN Red List. We can then track individual cetaceans over time and between locations on the basis of their unique photo-IDs. The results of this research inform management decisions and enhance recovery efforts for this species. Learn who you should contact when you encounter a stranded or injured marine animal >.
