    I think that the manatee cannot tolerate cold water while a larger
    marine animal like the whale because of evolution. Both mammals are
    very old. Through this time of their existance our planet has changed
    drastically. When we went through the ice age, whales may have been in
    the frigid north and manatees in the south. Whales probably had to
    adjust and become bigger and fatter to feel warmer. Manatees may have
    stayed in the warmer climates and didn't have to adjust as much,
    therefore they cannot survive in the artic climate.
