Most interesting Blue whale fact is that they are one-of-kind creatures to ever exist.
Blue Whale is the biggest animal in the world. There is no single animal on Earth that has been recognized as being larger than a Blue Whale.
In fact, they’re the biggest to ever live. That means the biggest dinosaurs didn’t match the size of a Blue Whale.
Blue Whales are so big that their heart is as big as a car like mini cooper and their tongue alone can weigh more than a fully grown elephant!
Below is the list of 10 facts about Blue Whales:
10.Hippos are closest living relative to whales
Fossil study of the long-extinct animals which lived on this planet million years ago confirms that cetaceans (Ocean mammals) are the closest living cousins of the Hippopotamus.
The analysis of their fossils especially their teeth led the Paleontologists to conclude both whales and hippo came from a forefather of anthracothere who migrated from Asia to Africa about 35 million years ago.
It probably swam there as Africa was then an island surrounded by water.
All this means that the modern hippo has evolved in Africa independently and is a truly native animal on the continent.
09.Blue whales don't sleep like us
It is one of the interesting fact about about the Blue Whales that like most sea mammals that they don’t sleep like us (terrestrial mammals).
If a blue whale sleeps as other mammals do, they will drown in the water deeply & may die due for suffocation.
Evolved with an involuntary respiratory system, only half part of their brain is closed down during sleep.
The other part remains ready for controlling the blowhole and starting each breath.
They stay silently in a flat place when the whales sit or float slowly next to another whale. It is renowned that sperm whales rest vertically.
08.Whale "vomit" is used in perfumes & is very expensive
A Blue Whale’s diet comprises krills (Shrimp-like creatures) and can eat up to 40 million krills in a single day.
But just like any warm-blooded mammal it sometimes vomits.
Ambergris is marine excrement produced from the abdomen of whales that is thought to help digestion.
Discharged from the deep inner water away from the coast, it gets soft and rancid when vomited.
Years of saltwater and wind exposure turn it into something like a rock with a waxy texture and a pleasant smell.
A chunk of ambergris weighing 7 pounds can amount to more than $50,000.
It is extremely valued not only because it is scarce, but also because it is difficult to discover an artificial replacement for it as a perfume base.
07.All Marine mammals have nose like us (sort-of)
Blue Whales, like Fish, can not get oxygen from water to breathe.
A blowhole is on top of their bodies and is used when swimming to the surface to inhale in a large amount of air & exhale (There is a misconception that Whales exhale water, Its actually warmer exhaled air, this warmness condenses the water. Hence, giving that water fountain look).
A Blue Whale, unlike other species, has two rather than one blowholes.
They can maintain their breath submerged for up to 35 minutes.
Blue Whales have lungs that they use to breathe, the blowhole above his heart is the nostril.
The nostril is so big that a human baby can crawl through it.
06.Blue Whale milk's texture is like a toothpaste.
Whales generate milk as all mammals do to feed their babies.
It is one of the unusual information about whales that the mother provides her baby milk by enabling it to nurse or squirt to its mouth from the nipple.
The level of 35 percent-50 percent fat in the milk makes it as thick as a toothpaste. This texture allows it to pass without dissolving up with water.
A baby Blue Whale needs around 300 liters of milk every day, that’s the rationing amount of milk for an average family for the entire year.
05.Blue Whales' life expectancy is more than 80-90 years in the wild.
Blue whales are animals like humans recognized to inhibit the ocean with an approximate lifetime of 80–90 years.
It is estimated that the oldest recorded blue whale will live up to 110 years!
A lot of variables can determine how long a blue whale is likely to survive when it gets to maturity.
Some of these variables include human hunting, food production shortages and nutrition safety, weather change, air and noise pollution, emotional and physical health such as injuries are some factors that influence their age.
04.Blue whales are not actually blue
Yes, Blue Whale is not blue colored, but they appear blue. How can that be?
Well, when viewed underwater, they appear solid blue.
Their actual color is mottled gray color and we can see it when they are taken out of water.
The blue color, however, is only on the upper side of their massive body.
A blue whale’s underbelly has a yellowish hue color. This hue, however, is mainly because of millions of microbes living on their skin.
03.Their voice is really very loud
Not only are the Blue Whales the world’s largest animals, but they are also among the loudest in the world.
At 140 decibels, a jet engine sound can record, a blue whale’s call reaches upto 188 decibals.
They usually produce moans, groans, and pulses, and they can hear each other easily from a distance of 1,000 miles if conditions are right.
That means they’re not only very loud, but their hearing sense is also very powerful!
Using sounds & songs (yes), they usually communicate with each other.
Yet, using their vocalizations and their hearing abilities to navigate through the ocean depths where light can not reach. The system is called navigation through echolocation.
02.Blue whales can increase their speed upto 20 mph
Blue whale habitat is worldwide but they follow certain seasonal patterns, spending summers feeding in polar regions and making the long trip to the Equator as winter comes along.
Traveling this long-distance with their massive body is not an easy task.
Their normal cruising speed is around 5 mph but they can increase their speed and swim at a speed of 20 miles per hour, though, if they get agitated somehow.
We, humans, are insignificant and for our pure appeasement, we can ruin anything.
By the first half of the 20th century, Blue Whales were almost on the brink of extinction because we killed them at large scale.
About 360,000 of these beautiful creatures were killed by us.
Why have they been slaughtered? Just because of whale oil.
This whale oil as valuable and have many medicinal characteristics.
In 1996, The International Whaling Commission stepped forward to protect these creatures.
As of today, here are only 4,500 (or less) Blue Whales remaining on this whole planet.
Blue Whales are endangered not just because of hunting there are various reasons like,
Increasing ocean pollution because of human behavior threatens their existence.
They also die for oil spills (from oil tankers), changes in environmental conditions (which is again mainly caused by human activity), high ocean traffic, as they often collide with big ships and end up dead.
Of natural food-chain Blue Whales are very important for the smooth flow of ecosystem they ensure no certain animal overpopulates ocean by doing this they maintain a proper balance.
Apart from eco-system these humble giants a living proof the wonders nature can create which is also important for making sure our future generation see these beautiful creations.
These were some of unique Blue Whale facts & if you really want them to survive in future share this post on your social-media & make sure your friends know about information.
Create awareness & compassion and save these helpless animals.
