    I am writing an essay on why whales can grow so large. I am also planning several other web pages on why animals are the size they are.

    In the process I am collecting statistics, so why not put them on the Internet. I have given you freely rounded, ball park figures. I am roughly changing figures from pounds or tons to killograms, kgs.

    My sources are the American Cetacean Society and Wikipedia. You can go to these and other sources for better figures, but this will give you the rough size ratios.
