Here's a breakdown:
* Cold Waters: Killer whales are most commonly found in cold and temperate waters, like the Arctic, Antarctic, and the Pacific Northwest. They are very well-suited for these environments thanks to their thick blubber layer and specialized blood vessels that help regulate body temperature.
* Warm Waters: Killer whales can also be found in tropical and subtropical waters, though they are less common. In these warmer areas, they may need to make adjustments to their hunting and foraging strategies.
Overall, killer whales are incredibly resilient animals capable of adapting to various climates. However, they do prefer colder waters and their populations are generally larger in these regions.
