How Big Is the Biggest Whale?

You may have heard of dinosaurs. They known for their size and strength. But do you know that the biggest animals ever lived on Earth are not dinosaurs? Yes, whales are the biggest animals of this planet.

Among the whales, blue whales are the largest ones. They can be as long as 111 feet. But why are they so big? According to scientists, there are two reasons for their massive size. The first reason is that these animals live in the ocean, so they have a good deal of room to grow.

The second reason is that the feelings of weightlessness in the water. Unlike humans, these large animals don’t support their body weight with their skeletons. Instead, they use the buoyancy of water to keep their bodies afloat.

It’s interesting to know that blue whale’s diet comprises mostly a small shrimp-like animal called krill. The whale sucks in a huge amount of water through “baleen”, which is part of their body. When the whale shuts its mouth, the water is forced out, thus leaving behind only fish and krill.


You may think that these huge creatures may be dangerous, but It’s not true. Blue whales don’t usually attack humans. As a matter of fact, they share a few similarities with us humans.

Unlike other fish, blue whales are on the list of warm-blooded animals, which means they have to breathe air.

According to research studies, blue whales are intelligent and social animals. Moreover, they have a special language to exchange messages with other whales. Let’s take a look at some other facts about whales as far as size goes.
