The humpback whale is a mammal. It lives in oceans all around the world. This place is deep and salty.
The humpback whale eats krill and small fish. It travels thousands of kilometers each year between cold feeding waters and warm waters where calves are born.
The humpback whale has baleen plates instead of teeth. These strain tiny animals out of huge gulps of seawater. It is about 16 meters long.
Baby humpback whales are called calves. A newborn calf drinks its mother's milk and can gain about 45 kilograms a day.
