Animals We Had No Idea Were Actually Shockingly Massive

The World's Biggest Whale Skull

The blue whale is the largest mammal on earth. They grow up to 98 feet and weigh 190 tons. These enormous whales are mainly found in the northeastern Pacific Ocean, and they used to be abundant until their population was depleted by whalers back in the 1800s.

Just by looking at its skull, you can imagine how large the rest of the animal must be. The man looks like a little mouse compared the the skeleton. In fact, blue whales are so large that their hearts alone weigh as much as a car.
