How long is a blue whale?
The blue whale is the largest animal on earth (growing larger than even the biggest of dinosaurs were). A 100 foot blue whale is as long as three school buses. Blue whales grow to about 70 to 80 feet in the northern hemisphere (north of the equator) and 90 to 100 feet in the southern hemisphere (south of the equator). Female blue whales grow larger than males. The longest blue whale ever recorded was 110 feet.
