Is There Really A Megalodon Shark – Ancient megalodon sharks may have been around 2 meters long at birth and may have grown much larger by eating unfertilized eggs in the womb.
The fossils were found in the 1860s in a 15-year-old rock and are now housed at the Royal Belgian Institute of Natural Sciences. Studying the shark’s vertebrae allowed them to estimate its body size at different stages of its life.
Is There Really A Megalodon Shark
“Megalodon was about two meters tall at birth, indicating that it must have given birth like all modern sharks,” Shimada says.

Just as a tree trunk has growth rings, a shark’s vertebrae have growth bands. After reading this, Shimada and his team reveal that this megalodon died at the age of 46.
They relied on data from its teeth to estimate its body size. This is because a shark’s teeth can usually be repaired because its skeleton is made of cartilage rather than bone. Studying rare vertebral remains is essential to learning more about ancient sharks, says Jack Cooper of Swansea University, UK.
Shows that young sharks, like most modern sharks, ate eggs that were not sealed in the womb to survive – a phenomenon known as fetal cannibalism.
“As a result, only a few children live and grow, but each of them can grow in size at birth, giving them the chance to become large monsters,” Shimada says.

Although new research has provided information about the growth of megalodons from birth to middle age, we still know little about the growth of megalodons later in life.

WASHINGTON, June 27 () – Megalodon, the huge shark that was the scourge of ancient seas and the star of today’s movie theaters, was named after its “big tooth” – and for good reason. Its fangs – up to seven centimeters (18 cm) long – can tear apart any animal in the deep blue sea.
Everything You Need To Know About The Megalodon: Size, Teeth, Name
These teeth provide a more complete picture of this extinct beast, and analysis of the mineral composition of the enamel flesh confirms that the megalodon was warm-blooded, a trait scientists believe contributed to its great success and downfall.
Researchers estimate that megalodon, which reached lengths of 50 meters (50 feet) and possibly 20 meters (20 feet) while hunting marine animals including whales, could boast a maximum body temperature of 81 degrees Fahrenheit (27 degrees Celsius). and could support her. It is approximately 13 degrees F (7 degrees C) above the surrounding seawater.
Perhaps this made the megalodon a powerful monster – a strong swimmer, capable of powerfully digesting food and, importantly, tolerating cold water, which allowed it to expand its population almost throughout the world.
Most fish are cold-blooded (ectothermic), their body temperature depends on the surrounding water. But only a few of them are warm-blooded, endothermic, and their body heats up. Examples include other sharks, including today’s great white shark.
Facts About Megalodon, The Giant Prehistoric Shark
“The living equivalent species today in terms of food and body temperature are the great white shark and, to a lesser extent, the mako shark. Although, as our research has shown, megalodon was much warmer than both modern ones. “Apex predators, that’s what makes megalodon unique,” said geochemist and paleoclimatologist Michael Griffiths of William Paterson University in New Jersey, lead author of the study published in the journal Proceedings of the National Academy of Sciences.
“One theory is that they were endothermic in nature – that some parts of their body were warmer than other parts, while their body temperature was high and the same as the whole body of large animals,” says scientist at UCLA who studies space and oceans. study author Robert. Eagle said.
Megalodon, perhaps the largest shark of all time, appeared about 23 million years ago and then disappeared about 3.6 million years ago amid falling ocean temperatures and sea levels.
“But the fact that these animals went extinct shows the risk—or cost—of being warm-blooded, because being warm-blooded requires constant food consumption to maintain metabolism,” paleobiologist and study author Kenshu Shimada of DePaul University. in Chicago they said.
Megalodon Shark Facts
“It is possible that there were changes in marine life due to a cooling climate that resulted in shrinking oceans, changing habitats and changing the types of food that megalodon depended on, such as marine animals, which became scarce. megalodon extinction,” Shimada added.
Scientists had previously suspected that megalodon was warm-blooded, but this study provided the first evidence of strength. The researchers analyzed the geochemical properties of fossil megalodon teeth to determine the temperature at which minerals formed in the enamel-like tissue—an indicator of body temperature.
After being spotlighted by the great white for decades in popular culture (think of the 1975 blockbuster Jaws and its endless generation), megalodon is now in the spotlight thanks to the 2018 film The Meg and its sequel The Meg 2: The Meg. . Trench..”
“Megalodon in the fossil record is mainly represented by only teeth and a few vertebral bodies,” Shimada said. “Unlike books and movies that portray megalodon as a huge, terrifying shark, the truth is that we still don’t even know what it looked like or how it lived. This is why ‘megalodon science’ continues to be an exciting field of study.” Summer blockbuster “Shark Fest” began on August 10th, if you believed otherwise. The film, of course, is not positioned – even superficially – as a documentary (note, Discovery Channel), but if

If the franchise has taught us anything, it’s that a spark of imagination only needs a little more than a breath of air to ignite a fire.
“People ask me [if megalodon is still alive] every day,” says Dana Ehret, curator of paleobiology at the New Jersey State Museum. He adds, in a good way: “The answer is no.”
The true story of Megalodon may not end with man versus shark – but its legacy is no less cinematic.
In its time, Megalodon was a force to be reckoned with. These giant rodents first emerged about 15.9 million years ago as one of the strongholds of the last extinct line of greattooth sharks. Measuring up to 60 meters in length and weighing over 50 tons, the Meg was one of the largest predators to ever exist, and certainly the largest shark. Greg Skomal, a shark researcher and manager of the Massachusetts Division of Marine Fisheries’ recreational fisheries program, affectionately calls them “great white sharks on steroids.”
Megalodon Was No Cold Blooded Killer
Contrary to popular belief, great whites are not the long-lost descendants of megas. But they are all at the top of the food chain – at different points in history. Because of this, many theories about megalodon physiology and behavior come from great whites; however, scientists now know that the two species independently evolved the similarities without much genetic interaction.
To stay in top shape, megalodon may have fed on whales, dolphins and seals, eating a ton of food every day – a task made easier by its six-inch teeth.
They have the greatest bite force of any animal in history. Even if megalodon was an occasional predator, it was likely an active predator, as evidenced by the whale and dolphin bones scattered along the world’s coasts.
Megalodon teeth have revealed much of what scientists know about the creature, thanks in part to its numbers. Unlike humans, sharks constantly rotate their teeth, shedding 20,000 or more teeth into the surrounding waters over a lifetime. Following each rejection event, five new rows of teeth appear, arranged like concentric roulette wheels, waiting to take the place of their predecessors. Large human teeth number in the thousands, and these fossils provide valuable information about the beast, according to Hans Sues, curator of vertebrate paleobiology at the Smithsonian Institution’s National Museum of Natural History.
