A baby blue whale gains about 200 pounds a day.
The blue whale is the largest animal on earth, ever. A big blue whale can be 100 feet long and weigh up to 150 tons. That's as large as a Boeing jet. Its heart is as large as a small car. Fifty people could stand on its tongue. Its spout shoots up at least 30 feet when it surfaces for air.
