Habitat
Fraser's dolphins inhabit deep, offshore tropical and subtropical waters, primarily in the Pacific and Indian Oceans, often at depths greater than 200 meters. They prefer pelagic environments away from coasts and are rarely found in shallow or nearshore areas. Their distribution spans from the equator to about 30 degrees latitude in both hemispheres.
Diet
Fraser's dolphins primarily feed on small fish, squid, and shrimp found in deep waters. They hunt in large groups using echolocation to locate prey during deep dives, often at night when their food sources migrate upward. Feeding occurs mainly in the mesopelagic zone, between 200 and 1000 meters deep.
Behavior
Fraser's dolphins are highly social, forming large pods of hundreds or even thousands of individuals that travel and hunt together. They exhibit energetic behaviors like leaping and bow-riding near boats, and are active both day and night with a preference for deep-water habitats. These dolphins are not particularly territorial and migrate seasonally to follow food sources.
Conservation Status
Fraser's dolphins are classified as Least Concern by the IUCN, with a stable population trend overall. Major threats include accidental bycatch in commercial fisheries and potential habitat degradation from pollution.
