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.
Short-finned pilot whale
Short-finned pilot whales, unlike the related long-finned pilot whale, are found in most waters around the world. They primarily inhabit warm tropical waters, but usually stay offshore in the deeper waters. They also tend to be found in areas with a high density of squid. Known populations are found in the North Atlantic stretching all the way south to northern South America, including the Gulf of Mexico and to Africa, as well. They are thought to migrate south into the western North Atlantic in the late winter/early spring. Other populations are recorded throughout the entire Pacific stretching from Japan to southern Guatemala, as well as the Red Sea and Indian Ocean.
