Whales are warm-blooded. They stay warm by layers of insulated blubber.
Fish are cold-blooded. Their bodies can naturally adjust to the changes of the temperature.
Whales breathe air like land mammals. They have a blowhole connected to their lungs to allow them to breathe in the air.
Fish have gills to breathe. The gills take oxygen from the water so fish can live underwater their whole lives.
Whales give birth to live young. They also produce milk to feed their newborns. Whales nurture their young to make sure they grow up healthy and able to survive on their own.
Fish lay eggs. Baby fish are fed nutrients through a sack that they carry around. Typically, baby fish are left to fend for themselves.
