Dinosaurs weren't the biggest animals to ever exist, and the current champ is still around today!
Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the ocean at up to 100 feet long and upwards of 200 tons.
Did you know that a blue whale's member can reach a length of up to 8 feet? That's taller than a professional basketball player!
Also, a blue whale's heart is the size of a car, and each of it's lungs the size of a bathtub. Their mouths can hold 100 people inside, and they eat 4 tons of fish every day. That's as much meat as 64,000 hamburgers!
