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.
