members of the order Cetacea. Although whales spend their

species of whale, the great Blue whale, is the largest creature
that has ever lived. Larger than the largest of ancient
dinosaurs, blue whales can grow to be more than 100 feet
long and weigh more than 150 tons. Of course, not all whales
are as large as the great blue. The Pilot whale, for example,
grows to about 28 feet. And those popular members of the
whale family, porpoises, range from 3 to 13 feet in length.
