From Head to Tail: BIG
What if your eyeball were the size of a baseball? What if your heart weighed 285 pounds? You might be a gray whale! A 35-ton gray whale weighs about the same as 10 large elephants. Whales can grow so huge because they live their entire lives in water and need not support their own weight. See how a 45-foot-long whale compares to a man and to a 45-foot-long lineup of students!
