World's Largest Creature Ever

The dinosaurs were massive, especially some of the large herbivores such as Brachiosaurus. However, did you know that the biggest creature to ever live is still alive today? At up to 30m in length and weighing over 180 tonnes, the Blue Whale is the largest creature of all time. This picture is a to-scale size comparison of the Blue Whale to other famous large dinosaurs, the Elephant (largest land animal alive today) and to show just how small we are - a human.
