Top 5 Astounding Facts About Blue Whales

Did you know that blue whales are one of the largest animals on the planet, if not the largest animal on the planet? Do you have any doubts? Okay, here are some examples of comparisons for your consideration:

  • The average lifespan of a blue whale is between 80 and approximately 90 years. As a result, a "average" whale is likely to be as old as your parents or grandparents.
  • In a straight line, the length of the blue whale is equal to the length of ten London city buses.
  • The blue whale is only truly blue when it is swimming in water.

While the previous set of facts will pique your interest, the following set of facts will allow us to delve deeper into some interesting facts about the blue whale. So, how about we get started?

1) They are extremely large in stature

Scientists have confirmed that the blue whale has the largest of the following three organs: the mandibles, the brain, and the penis, of all the animals that have ever lived on the planet. This just goes to show how enormous the blue whale truly is. What a wonder it is one of the largest creatures on the planet at this point in time!

2) Babies who are enormous in size

An average baby blue whale that was born last night, for example, is already as heavy as two pickup trucks and as long as about five fully grown men stacked head to toe, assuming that they were all laid out on the ground at the time of their birth. Shocking? There's more: they gain approximately 90kg or more per day in their first year alone, despite only consuming breast milk and nothing else.

3) They are frequent travellers

Blue whales are attracted to extremely cold water, such as that found in the Arctic and Antarctica. This is due to the fact that most of their favourite foods can be found in large quantities there. On top of that, they prefer to migrate towards warmer waters when they do so, as this is the most favourable environment for reproduction. When blue whales overwork themselves in hot environments for an extended period of time, they overheat, just like car engines.

4) They move extremely quickly.

It's understandable that you'd be concerned, given the sheer size of these creatures. What is their maximum speed? Will, you're moving pretty quickly. This is especially true given that their average speed can be as fast as a sailfish, and when threatened, they can move at speeds comparable to those of a gazelle. One of the best ways to observe blue whales in their natural habitat is by private boat charter.

5) They Consume a Large Amount of Food

Despite the fact that they are predators, these animals appear to be calm and gentle at first glance, especially considering that they are the type of predator that has no fear of being attacked by any other creature at all. As a result, despite the fact that you might assume they scavenge for plankton and seaweed while travelling the oceans, they are carnivores.

They feed on krill, which is a small animal about the size of your thumb, by squeezing it between a set of fringed plates in their mouth, which serves as their teeth because they lack teeth. They are foodies not only because they consume their food whole, but also because on a good day, the average blue whale can consume approximately 3 tonnes (or more) of krill, which is equivalent to approximately 30 million krill on a single day.


There has always been something fascinating about the story of the blue whale, from its size to how it eats, its colour, weight, and biological and economic significance. If you ever get the chance to see one, it is a breath-taking sight, and learning about them is just as exciting as it can possibly be. One of the most effective ways to observe the magnificent blue whale species in their natural environment is through the use of a whale watching cruise operator.
