Emmanuel Klump, age 7, of Louisville, Ky., for his question:

WHICH IS THE BIGGEST WHALE?

We have several names for him. But everybody agrees that the biggest whale is also the biggest animal in the world. What's more, he is the biggest animal that ever lived on the planet earth. He may be called the blue whale, or the blue baleen whale or the sulphur bottom whale. This gentle giant of the deep ocean is 100 feet long and the distance around his bulging waist is 45 feet. His total weight is about 120 tons.
