The Blue whale is believed to be the largest animal ever to exist. But nobody remembers number two. Fin whales are the second largest animals on the planet, weighing in at around 80 tons. And they’re very mysterious creatures. Now scientists have gained better access to the giant whale’s secret lives – almost accidentally.
