FILE - This Jan. 21, 2016 file photo shows tourists looking out on the horizon as their boat searches for dolphins in waters off Waianae, Hawaii. Federal regulators are proposing a widespread ban on swimming with Hawaii's spinner dolphins to allow the nocturnal creatures to rest during the day. The National Marine Fisheries Service proposal announced Tuesday, Aug. 23, 2016, would allow some limited exceptions, given dolphins sometimes approach people. (AP Photo/Audrey McAvoy, File) less
