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.

In winter, the whales' distribution is particularly mysterious. There have been a few sightings close to shores in California and even Baja, particularly in the 1990s along locations like La Jolla, Point Sur, Big Sur coasts, Piedras Blancas, San Simeon, Point Montara, and in Santa Barbara Channel. They have been rare, of short duration and none since 1998. Largest numbers of whales sighted at one times in eastern Pacific outside of SE Bering Sea since after the late 20th century were of 8 animals off Destruction Island in 1959, sightings off Cape Flattery of 3 whales in and 1967 and 6 or 7 whales in 1973, 4 whales at the mouth of Yakutat Bay in March 1979, a pod of 2 or 3 whales at Three Arch Rocks in Oregon in 1994, and likely a pair seen off southwest of San Miguel Island in February 2015. In the western Pacific, the latest of recent records were of a close encounter by a yachter with a cow-calf pair off Sajima Island in Sagami Bay in the early 2000s and a pod appeared close to the pier on Mikura Island in 2008.
