Prehistoric dinosaurs are not the largest animals to ever live on the earth. The largest animal to ever populate the earth is the blue whale. About 120 years ago, there were over 200,000 blue whales in the earth's oceans. Over hunting reduced the blue whale population to less than 2,000. International law began protecting blue whales and they are now an endangered species. Look at the graph below that shows the blue whale population. Today, because of international protection, the population has rebounded to around 20,000. "Blue Whale."
