Besides giving the obvious answer that blue whales live in the ocean there is a more complex answer for you to think about. Lucky for the blue whale being nearly 20 times larger than the biggest of elephants and 10 times larger than the scary tyrannosaurus rex the blue whale never had to worry about being hunted y man because they were just to big and fast to catch. These whales spend a lot of time moving north to south and then south to north following the food they eat and keeping in waters which are the perfect temperature for them to live in.

It is the cooler temperatures that the blue whales like such as far north around Iceland and Norway and around the coast of Ireland. The Atlantic Ocean is where these majestic mammals of the deep love to live, feed and breed because the water temperature there is perfect for a mammal that has dozens if not hundreds of tones of blubber around its body. The blue whales are capable of traveling thousands of kilometers so you can also find them in the warmer Pacific Ocean. The blue whale just like many other whale species are mainly comprised of blubber and it is not unusual to see them alongside an iceberg which shows just how effective their natural insulation can be.

Unfortunately for the blue whale their habitats are becoming less which is a problem for something of such a great size. With the melting of the ice caps the fresh water that is running off into the ocean means that the whales have to stay away from this land mass otherwise they will drown in themselves in the freshwater which they cannot breath. Blue whales can also be found further north as far as the equator around America and off the coast of Africa which is where they need to go to feed during the colder seasons.
