Off the Atlantic coast of the United States tiger sharks are found from Cape Cod, Massachusetts, to the Gulf of Mexico and Caribbean Sea. Off the Pacific coast tiger sharks are found from southern California southward. In the western central Pacific, tiger sharks are found in the Hawaiian, Solomon, and Marshall Islands.
Tiger Shark inhabits coastal waters close to shore to outer continental shelf and offshore including oceanic island groups.
