Here's a breakdown:
* Cold waters: Killer whales are often found in polar regions and along the coasts of Alaska, Canada, Greenland, and Antarctica. They can survive in waters near freezing point.
* Temperate waters: They are also common in temperate zones, such as the Pacific Northwest, Norway, and the coasts of Argentina and Chile.
* Warm waters: While they can be found in warmer waters, they are less common and tend to prefer deeper, cooler waters in those regions.
It's important to note that different populations of killer whales have adapted to different environments. Some populations are more specialized to cold waters, while others are more adaptable to warmer waters.
