Why do killer whales prefer to be in cold water than warm water?

omgreakingee thank you soo much , your a life saver I finished the last question in my packet (reserch) in school :) thank you :)

Except I think it’s wrong. Whales are mammals and as such are warm blooded animals. their body temperature will be above the temperature of the cold water in which they swim - enabling them to lose thermal energy to the surrounding cold water, more quickly than they woul lose it to warmer water. If they spent too much time swimming that massive bulk through warm water, they would never be able to maintain a proper body temperature and would overheat.

Also the cold water is more nutrient rich and provides them a larger food supply the tropical waters cant sustain there dietary needs

I agree, …..

….. I think a lot of whales feed almost continuously, for much of the time, on small creatures such as krill that live in the colder waters.
