Blue whales are a very interesting creature. The first fact that makes them so intriguing is the sheer amount that they eat. Did you know that it’s possible for a single blue whale to eat between four and eight tons in a single day? To put that in perspective, an average car weighs between two and three tons. What’s even more incredible about this fact is blue whales eat this huge amount by consuming krill. A single krill only weighs one to two grams. In one pound, there are 453 grams. 2,000 pounds make up a ton. When you start doing that math, it’s almost mind boggling how many krill blue whales can eat in a single day!

When you’re dealing with a creature that is large as a blue whale, it can be hard to truly wrap your head around its size. To give you an idea, just the tongue of a blue whale can be as big as an entire elephant. Since we’ve already used the car for a size comparison, it can also be useful to know that a blue whale’s heart is equivalent in size to a regular car.

Blue whales also have the ability to move very quickly. When they are going at their average pace, they cover around five miles an hour. However, when a blue whale needs to get somewhere, they are able to cover a full twenty miles in just one hour. Speaking of miles, if you were a blue whale, you wouldn’t need a cellphone. The reason is because they can communicate with each other over a span of one thousand miles!
