Killer whales are often found in warm areas such as Florida, Hawaii, Australia, the Galapagos Island, the Bahamas, and the Gulf of Mexico and more temperate such as New Zealand and South Africa. Although they do show the Killer whales ability to venture into tropical waters such sightings are highly infrequent. Killer Whales are the most widely distributed mammal in the world. Killer Whales seem to be the most abundant in coastal waters, but are also found in Open Ocean. There are five different forms of Antarctic Killer Whales that have different distributions.
