Megalodon: The Beast That Lives Again | Everything about the Megalodon shark.

Is Magalodon alive? The megalodon appears as a shape on the sonar fish detector of researchers from the Atlantic Shark Institute that works in shark research and protection. Interesting Fact about Megalodon its Length, Size, Extinct, Film, and Comparison with Blue Whale.

Has the largest shark Megalodon alive ?

On a recent research expedition off the coast of New England, local shark scientists noticed a gigantic, 50-foot-long shark-like shape on their fish finder. Did the renowned megalodon giant shark species make a comeback?

"On a recent shark research expedition, we were all amused to see this shape display on our fish finder for several minutes," the Atlantic Shark Institute, based in Rhode Island, said, "We estimated the 'Megalodon' to be roughly 50 feet long and 40 tonnes based on the length of the image!"

Unfortunately for shark fans, the megalodon has not returned. According to the researchers, the 'Meg' gradually changed shape as a school of mackerel moved around.

Megalodon History:

Megalodon sharks lived between 4 million and 22 million years ago all over the earth and could grow to be as long as 65 feet long. In comparison, today's largest great white sharks can grow to be 20 feet long.

Adult great white sharks that visit Cape Cod typically range in size from 11 to 15 feet. It was Carnivore and its Average life span of around 20 to 40 years. The average Weight was between 50 to 75 tons.

Megalodon Extinction:

Climate change:-

During the time that Megalodon existed, the Earth underwent several changes that had an impact on marine life. A cooling trend that began in the Oligocene 35 Mya resulted in ice at the poles. The stalled Gulf Stream prevented nutrient-rich water from reaching important marine habitats, potentially affecting their food sources. Geological events shifted currents and precipitation patterns.

The Plio-Pleistocene epoch saw the greatest fluctuation in sea levels in the Cenozoic era, between 6 million and 12 thousand years ago, due to the expansion of glaciers at the poles, which negatively affected coastal environments and may have contributed to its extinction, along with that of several other marine vertebrate species.

Megalodon's range was limited to diminishing warmer waters because it did not appear to extend into colder waters, and it may not have been able to retain a considerable quantity of metabolic heat. Fossil evidence indicates the absence of megalodon in areas worldwide where water temperatures declined sharply during the Pliocene epoch.

Changing Ecosystem:-

The Miocene epoch had the highest diversity in marine mammals, such as baleen whales, with over 20 identified Miocene genera compared to only six modern genera. Such diversity provided an ideal environment for a megalodon-like predator. 

Many mysticetes species had become extinct by the end of the Miocene; surviving species may have been faster swimmers and so more elusive prey. Furthermore, tropical whale diversity and abundance fell due to the closure of the Central American Seaway. 

Megalodon's extinction corresponds with the decline of numerous minor mysticete lineages, and it is possible that it was entirely dependent on them for food. Competition from other marine mammal predators, such as macro predatory sperm whales that developed in the Miocene and killer whales and great white sharks in the Pliocene, may have contributed to the megalodon's decline and extinction.

Megalodon's extinction paved the way for subsequent changes in marine communities. The average body size of baleen whales increased significantly following their extinction, though this could be due to other, climate-related factors. 

Increasing baleen whale size, on the other hand, may have contributed to the extinction of megalodon, as they may have preferred to hunt smaller whales; bite marks on huge whale species may have been caused by scavenging sharks.

Megalodon facts:

1. The bite of a megalodon could destroy a car.
2. The largest megalodon tooth ever discovered was around the length of a TV remote;
3. Megalodon's Teeth Were Over Seven Inches Long
4. Whales and Dolphins Were Food for the Megalodon
5. Megalodon Had Worldwide Distribution
6. Megalodon was too big to swim near the shore.
7. Megalodon is thought to have consumed 2,500 pounds of food every day.
8. Even though both megalodons and dinosaurs are extinct, they never coexisted. The dinosaurs became extinct approximately 65.5 million years ago. Megalodons appeared later.
9. Female megalodons were nearly twice as big as males.
10. They are Three times as big as the largest sharks in the ocean today.

Megalodon film:

In novels and films, such as the 2018 sci-fi thriller "The Meg," Otodus megalodon is commonly depicted as a massive, monstrous shark. and there are many other films based on megalodons like Megalodon (2004 film), and Megalodon rising.

Megalodon vs blue whale:

Humans have been fascinated by enormous beasts since the beginning of time. Two massive sea creatures come to mind in the aquatic world:

The blue whale and the megalodon.

Even now, the blue whale holds the record for the largest animal on the planet, but the fundamental question we all seem to have is,

Was the megalodon indeed smaller than the blue whale of today?

Join us as we discuss the differences.

Megalodon was the largest shark that existed between 2.5 and 1.6 million years ago. The blue whale is the world's largest animal, extending up to 30 meters in length and weighing up to 150 tonnes.

Blue whales are the largest mammals to have ever lived on the planet. They can grow to be up to 35 meters long and weigh up to 140 tonnes, making them more than twice as heavy as the next largest species, the megalodon, which was only about 25 meters long and weighed around 70 tonnes.

Humans have attacked blue whales for centuries for their meat, blubber, and skin, which are utilized in numerous items such as leather, soap, and paint.

Why Do So Many Megalodon Teeth Exist?

Only a single fossilized remaining of the world's most giant shark is in the form of teeth. The majority of sharks produce teeth throughout their lives. A shark's teeth can be broken every two to three weeks depending on its nutrition. 

A shark can consume 40,000 teeth in a single lifetime, which means shark teeth can be found all over the ocean floor.

There are increased chances of these teeth becoming fossilized because there are so many of them. Furthermore, a shark's tooth is the hardest piece of its skeleton.

Shark bones are comprised of soft cartilage, which is the same material found in our ears and noses.
