Blue whales are so large that, in most oceans in the world, if you were underwater with an adult one, you wouldn't be able to see one end from the other.
If one were swimming in the nutrient-rich waters near Vancouver, for instance, the body of the whale would disappear into the distance because the visibility is too obscured (by plankton and other things in the water itself) to take in the animal's entire 30-metre length—about the same as three typical shipping containers.
But if you want to see what it would be like to examine a blue whale up close, life size, here's a web page (via Mirabilis) where you can do it.
