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.
Wildlife of China
Whales were historically abundant along Chinese and Taiwanese waters especially in winter and spring seasons where they come to coastal areas to breed and calve while especially baleen whales other than those migrated from outer pacific and Sea of Japan swam northward to feed in Yellow and Bohai basins during warmer seasons. Most of large whales in Taiwan were recorded prior to 1952. In imperial times, villages along the coast of the Leizhou Peninsula in Guangdong hunted whales and made offerings of whale oil to the emperor in Beijing. On the other hand, however, like among other nations such as in Korea, China, Ebis in Japan, Indonesia, among Indochina including , regarded as the "King of the sea", the "Dragon emperor in the ocean", or "Dragon Soldiers" in almost entire coastal regions excluding above mentioned Hainan and Leizhou, as when whales were seen, fishermen and boats had to make ways for them and wait the whales to pass. In Chinese mythology, for example, "Yu-kiang", the ruler of the sea, is said to be a whale with arms and legs. Indigenous tribes on Taiwan also recognized the presences of large whales and representing whales in their local myths and folklores.
