Just think, the blue whale is one hundred feet long; longer than three school
buses put together. Our class measured a string a hundred feet
long. We took it out on the playground to see how long it would
be.
The boy who pulled the string all the way out looked very small
because he was so far away. The blue whale weighs more than thirty
elephants, or more than the three largest dinosaurs that ever
lived. Just his heart weighs over a thousand pounds.
Whale babies are called calves. Their mothers are cows and the
males are bulls. A blue whale only has one baby every two years.
It takes ten to eleven months to be born. The calf has to stay
with the cow for seven months. It weighs three tons when it is
born and is twenty-three feet long.
