Killer whale
Information for offshore regions and warmer waters is more scarce, but widespread sightings indicate the killer whale can survive in most water temperatures. They have been sighted, though more infrequently, in the Mediterranean, the Arabian Sea, the Gulf of Mexico, and the Caribbean. Over 50 individual whales have been documented in the northern Indian Ocean, including two individuals that were sighted in the Persian Gulf in 2008 and off Sri Lanka in 2015. Those orcas may occasionally enter the Red Sea through the Gulf of Aden. The modern status of the species along coastal mainland China and its vicinity is unknown. Recorded sightings have been made from almost the entire shoreline. A wide-ranging population is likely to exist in the central Pacific, with some sightings off Hawaii. Distinct populations may also exist off the west coast of tropical Africa, and Papua New Guinea. In the Mediterranean, killer whales are considered "visitors", likely from the North Atlantic, and sightings become less frequent further east. However, a small year-round population is known to exist in the Strait of Gibraltar, mostly on the Atlantic side. Killer whales also appear to regularly occur off the Galápagos Islands.
Fin whale
Very little information has been revealed about the ecology of current migration from Antarctic waters are unknown, but small increases in sighting rates are confirmed off New Zealand, such as off Kaikoura, and wintering grounds may exist in further north such as in Papua New Guinea, Fiji, and off East Timor. Confirmations in Rarotonga have been increased recently where interactions with humpback whales occur on occasions. Finbacks are also relatively abundant along the coast of Peru and Chile (in Chile, most notably off Los Lagos region such as Gulf of Corcovado in Chiloé National Park, , port of Mejillones, and Caleta Zorra. Year-round confirmations indicate possible residents off pelagic north eastern to central Chile such as around coastal and Pingüino de Humboldt National Reserve, east of Juan Fernández Islands, and northeast of Easter Island and possible wintering ground exist for eastern south Pacific population. They are known to make mixed groups with other rorquals such as blue whales and sei whales. Their recovery is confirmed vicinity to various subantarctic islands such as South Georgia and Falkland, but unknown in other historical habitats including Campbell Island, Kermadec to Chatham Islands, Tristan da Cunha, and Gough Island.
