The Blue Whale (Balaenoptera
musculus) is the largest animal to have
ever lived, dwarfing even the largest
dinosaurs. Adults average 80 to 105 feet
in length and weigh up to 200 tons. The
tongue is as heavy as an elephant, and
the heart the size of an automobile. |

The Gray Whale (Eschricktius
robustus)
has one of the longest migrations of all
mammals -- 10,000 to 14,000 miles between
their feeding and calving grounds, round
trip. Unlike other baleen whales, the
gray whale is a bottom feeder. |
