A blue whale is the largest animal in the world, no other animal can be identified as being larger than a blue whale.
What is the size of the blue whale?
The average length of adult blue whales is 24.1 m (79 ft).
In fact, they’re the biggest ones that ever lived. This means that the largest dinosaurs did not match the size of the blue whale.
These marine mammals are so big that a car like a miniature chicken coop is as big as the heart of a blue whale, and their sole alone can weigh more than an adult elephant!
The largest blue whale
The longest reported whale was 30.5 m long.
However, only one blue whale was 29.9 m long, the longest scientifically measured length from beak to tail.
Weight of blue whales
Males in Antarctica weigh on average 112 tons, females 130 tons.
If you are looking for information about interesting facts, you will find a list of 10 facts about blue whales below:
10. Hippos come closest to whales
A study of the fossils of long dead animals that lived on this planet a million years ago confirms that whales (marine mammals) are the closest living relatives of the hippopotamus.
Analysis of their fossils, especially their teeth, led paleontologists to the conclusion that both the balaenoptera and the hippopotamus descend from an anthracotta ancestor.
These animals migrated from Asia to Africa some 35 million years ago.
He probably swam there because at that time Africa was an island surrounded by water.
All this means that the modern hippopotamus has developed independently in Africa and is truly an indigenous animal on the continent.
9. The blue whales are awake like us
It is one of the interesting facts that blue whales, like most marine mammals, do not sleep like us (land mammals).
If a blue whale sleeps like other mammals, it drowns deep in the water and can die of suffocation.
Evolution with involuntary breathing, only half his big brain shuts down when he’s asleep.
The other party remains ready to check the chimney and start each breath.
They remain silent in a shallow area when the whales sit next to another whale or slowly swim next to it. Sperm whales are known to stand upright.
8. Whiskots is used for the production of perfumes and is very expensive
The food of a blue whale consists of krill (shrimp) and can eat up to 40 million krill a day.
But like any warm-blooded mammal, it gets sick sometimes.
Ambergrises are marine faeces from the stomachs of whales, which are thought to promote digestion.
When it comes out of the deep sea, it gets soft and rancid when it vomits.
Years of exposure to salt water and wind make it a kind of rock with a waxy texture and a pleasant smell.
A seven-pound piece of amber can cost over $50,000.
It is highly appreciated, not only because it is rare, but also because it is difficult to find an artificial replacement for it as a perfume base.
7. All marine mammals have a nose like ours (so to speak)
Blue whales, like fish, cannot extract oxygen from the water to breathe.
The hole is located at the top of the body and is used to inhale and exhale large amounts of air when swimming to the surface.
It is wrong to believe that whales breathe out water, because the air they breathe out is actually warmer, this heat condenses the water, hence the fountain-like appearance.
The blue whale, unlike other species, has two holes, not one.
You can breathe underwater for up to 35 minutes.
The nostril (breathing tube) is large enough for a human child to fit through it.
6. The texture of blue whale’s milk is similar to that of toothpaste.
Whales, like all mammals, produce milk to feed their young.
An unusual knowledge about whales is that a mother gives her baby milk by allowing her to breastfeed or feed it from a nipple.
The 35-50% fat content of milk makes it as thick as toothpaste. This texture makes it possible to continue without dissolving in water.
A bluefin tuna calf needs about 300 litres of milk a day, which is the normal amount of milk for an average family throughout the year.
5. The life expectancy of blue whales in the wild is over 80-90 years.
Blue whales are the same animals as humans, recognized as oceanic inhibitors with an estimated lifespan of 80-90 years.
The oldest blue whale in history is estimated to be 110 years old!
Many variables can determine how long a blue whale is likely to survive as an adult.
Hunting, food shortages, food security, weather changes, air and noise pollution, emotional and physical health, such as injuries, are some of the factors that influence their age.
4. Blue whales are not really blue
Yeah, the blue whale isn’t blue, but it does look blue. How is that possible?
Well, if you look underwater, they all look blue.
Their real colour is grey and we can see them when they come out of the water.
Blue, however, only on the upper part of his massive body.
The belly of the blue whale is yellowish. However, this colour is mainly due to the millions of germs that live on their skin.
3. Your voice is very loud.
Blue whales are not only the largest animals in the world, but also one of the noisiest.
The sound of the jet engine can absorb up to 140 decibels, the cry of the blue whale reaches 188 decibels.
They groan and flutter most of the time, and are easy to hear at a distance of 1000 miles if conditions allow.
This means that they are not only very noisy, but also very noisy!
With sounds and songs (yes) they usually communicate with each other.
Thanks to their vocal and auditory skills, however, they can travel to the depths of the oceans where no light can penetrate.
This system is called echolocation navigation.
2. Blue whales can increase their speed up to 31 mph
Migration and Habitat
Blue whale habitat exists worldwide, but follows a regular seasonal pattern.
They take advantage of summer by feeding in the cold waters of the polar regions and make the long journey back to the equatorial Indian Ocean when winter arrives.
This seasonal migration is due to the fact that krill moves to warmer waters in winter.
Travelling long distances with their massive bodies is not an easy task.
Their normal cruising speed is about 5 miles per hour, but they can increase their speed and swim up to 31 miles per hour if they are somehow excited.
We humans are insignificant, and for our sheer peace, we can ruin everything.
Why are blue whales threatened with extinction?
In the first half of the 20th century. In the last century the blue whales were almost on the verge of extinction because we killed them on a large scale.
Approximately 360,000 of these magnificent creatures were killed by us.
Why were they stabbed?
Just for the whale oil. This whale oil is precious and has many therapeutic properties.
In 1996, the International Whaling Commission took a step forward to protect these creatures.
At this moment there are only 4,500 blue whales (or less) left on the entire planet.
Whales such as the sperm whale, humpback, killer and blue whale are not only threatened by hunting, but also for all kinds of other reasons, such as the increased pollution of the sea by human behaviour, which threatens their survival.
They also die from oil spills (from tankers), changes in environmental conditions (again mainly caused by human activities), heavy maritime traffic, attacks on ships, they often encounter large ships and eventually die.
In the natural food chain, blue whales are very important for the balance of the ocean ecosystem and have equal rights, because we humans have to live on this planet.
These are amazing facts about the blue whale for children.
