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.

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.
Also the cold water is more nutrient rich and provides them a larger food supply the tropical waters cant sustain there dietary needs
omgreakingee thank you soo much , your a life saver I finished the last question in my packet (reserch) in school :) thank you :)
:) thanks well thats ok , because our teacher gave us more time & said we could take it home so I could change some things up
You lose less energy in cold environments, and if they don't eat very often, they need to conserve their energy
THANKS GUYS :)
