But, under their fins and on their stomach they are white with some black markings.
Whales are also extremely large.
They can weigh up 35 tons. They eat from 4,000-5,000 pounds of food a day. That explains why they weigh so much. But, what they eat is so small, so they can take it all in. They eat krill and small fish.
