15 Interesting Facts About Blue Whales

The Blue Whale, a marine mammal, is larger than even the largest dinosaur and is thought to be the largest animal to have ever existed. They dwell in the Antarctic Ocean, the North Atlantic, North & South Pacific, and Indian Oceans.

The Blue Whale prefers the deep ocean, rather than coastal waters or bays, and can be found living in any of the oceans located around the globe. Blue Whales live typically between 80 and 90 years, with some reaching up to 110 years of age.

Because the blue whale is the largest animal to live on the planet, it has few predators. However, shark attacks and killer whales can injure or kill a blue whale. They usually pass away from wounds they receive in collisions with big sea vessels. So here are the 15 interesting facts about Blue Whales:

1. They Can Weigh as Much as 30 Elephants

These gentle giants typically weigh between 200,000 and 300,000 pounds or between 100 and 150 tons. Some can weigh as much as 441,000 pounds or 220 tons.

For comparison, an adult African bush elephant weighs up to 6 tons, so it may take 30 or more elephants to equal the weight of one blue whale.

2. They Deliver the World’s Largest Babies

Blue whale calves are the biggest babies on Earth, easily, and at birth already rank among the largest full-grown animals. They pop out at around 8,800 pounds with a length of some 26 feet.

They gain 200 pounds a day. With multiple billion-fold increases in tissue over the 18 months between conception and weaning, their development rate is probably among the quickest in the animal kingdom.

3. Blue whales are kept warm via an internal thermal insulator

Blue whales have evolved to the world’s coldest waters despite the fact that heat loss in the water is 27 times greater than on land.

The unpleasant reality is that commercial hunting for blue whale fat has contributed to the animal’s endangered state despite the fact that blubber makes up more than 25% of a blue whale’s body mass and serves as a kind of damage protection and thermal insulator.

4. Their Hearts Are Big

The blue whale has a massive heart. It weighs over 400 pounds and is about the size of a bumper car, making it the biggest heart in the animal kingdom.

The enormous heart of a blue whale may only beat twice each minute when it dives for food.

5. Blue whales get some of their blue colors from the sea

Blue whales appear to have a deep blue hue underwater, but when they surface, their true color is gray. They appear darker blue than they actually are due to the color of the water and sunlight.

Blue whales have light gray or yellow-white undersides, and the aggregation of minute, unicellular marine algae called diatoms in cold water is what gives their ventral regions their yellow color

6. Each blue whale has a distinct marking of its own

Prior to the advent of modern whaling in the late 19th century little was known about blue whales. But, today’s researchers have used photo-identification to discover that each person’s speckled pigmentation pattern is distinctive and a feature of the species.

In sharp images, blue whales may be clearly identified by their distinctive mottling. In fact, the marks are so intricately detailed that perfect copies are quite unusual. Researchers have been able to learn more about the life spans and migration paths of blue whales because of this method of identification.

7. They’re Very Loud

In actuality, blue whales are the world’s loudest mammal. The sound of a jet engine is measured at 140 dB; a blue whale’s cry is measured at 188. Others may hear their language of pulses, groans, and moans up to 1,000 kilometers distant.

The fact that baleen whales frequently sing these loud, low-pitched songs to communicate is a familiar observation. Adult blue whales make mating sounds during their mating seasons from late fall to the end of winter. These noises help in breeding selection and may be heard from great distances.

8. Maximum blue whale productivity comes from conscious slumber

 Despite the fact that blue whales hunt in the middle of the ocean, they must surface to breathe. Via twin blowholes protected by a large splashguard, they breathe in and out.

The blowholes are big enough for a kid to crawl through, although we don’t advise it. A vertical column of pressured vapor that may reach a height of nine meters is produced when blue whales surface to breathe and exhale.

Blue whales may dive deep for food, sometimes exceeding 500 meters, according to another statistic. They can stay underwater for up to 35 minutes; however, the majority of dives are just 10 to 20 minutes long.

Like other whales and dolphins, blue whales can breathe on their own. They only ever rest one-half of their brain at a time, never fully dozing out. The other half stays awake to prevent drowning.

9. They Live a Long Life

One of the species that live the longest is the blue whale. Similar to counting tree rings, scientists may estimate an individual’s age by measuring the layers of wax in their ears.

Although the typical life expectancy of blue whales is believed to be between 80 and 90 years, the oldest one they have found this way was assessed to be approximately 100 years old.

10. The blue whale’s migratory behavior is quite varied

Between cold-water feeding areas and warm-water breeding grounds, many whales, particularly baleen whales, frequently travel great distances each year. These migration patterns are very diverse, but we still don’t fully understand them.

Some blue whales seem to live year-round in environments with high production. In the Arctic and Antarctica, other blue whale populations migrate. As a result, they can occasionally be seen on both Antarctic and Arctic excursions.

Blue whales return to warmer waters, where there are better areas for giving birth when the feeding season is through. On lengthy migrations, blue whales have been seen to fast for up to four months while subsisting only on body fat stored during their feeding season.

11. They Consume a Lot of Krill

 Despite being the biggest mammal on Earth, krill, a microscopic aquatic lifeform resembling shrimp, is the main food of blue whales. Krill, as used in Norwegian, is a term for juvenile fish fry. A blue whale may consume up to 40 million krill, or around 8,000 pounds, each day.

Blue whales usually always inhabit regions with large krill densities, such as the Arctic Ocean, in order to sustain their diet.

Blue whales are unable to chew and break down food into tiny pieces because they lack the esophageal size necessary to swallow bigger sources of food. To state this truth simply, mature humans cannot be swallowed by blue whales.

12. There Used to Be Plenty

The blue whale was a common species before whalers learned how much oil it could yield. Nevertheless, the introduction of whaling fleets in the 20th century caused a sharp decline in their population, which was eventually protected globally in 1967.

According to the World Wildlife Fund, more than 350,000 blue whales were wiped off in the Southern Hemisphere between 1904 and 1967. An amazing 29,000 blue whales were killed in a single season in 1931, the peak year for whaling.

13. They Move Very Quickly

They make lengthy journeys, spending the summers eating in northern areas and returning to the equator as winter approaches.

They can accelerate up to 20 mph when necessary while having a 5 mph cruising speed.

14. The Future Is Unknown to Them

Although there is no longer a threat from commercial whaling, blue whale recovery has been gradual, and they are now at risk from new dangers including ship strikes and the effects of climate change.

Off the coast of California, there is one colony of about 2,000 blue whales, although there are only between 10,000 and 25,000 of them overall.

The species is considered endangered by the International Union for Conservation of Nature. Perhaps, over time, the oceans will once again be abundant with the greatest gentle giants in the world.

15.  The biggest animal to have ever inhabited Earth was a blue whale

 The blue whale, which may reach lengths of 30 meters, or three school buses, has never been found to have an Earthly counterpart that is bigger. In addition to having some of the biggest organs in the animal kingdom, they may weigh up to 200,000 kg.

Blue whales were able to grow larger than other creatures because of the low gravity of seawater. As an illustration, blue whale hearts may weigh up to 180 kg.

The fact that their brains are proportionately small—weighing just 7 kg, or.007% of their body weight—is also a truth. The shift of blue whales to marine life is considered to have started some 50 million years ago. Blue whales are all derived from land-dwelling animals.
