Why is the Blue Whale So Big?

Scientist don't really know for sure, but they are sure of one thing - as big as the ancient dinosaurs were they were never as big as the blue whale is. The blue whale is the largest creature to have ever lived on earth! One of the most important reasons that whales have become so large is they have more space - more room to roam. Remember: over 70% of the earth is covered in ocean water.

Another nice thing about living in the oceans, besides all the real estate,
