Megalodon, the biggest shark to have ever lived, roamed the seas for millions of years, preying on marine mammals and fish before finally going extinct. This apex predator was a massive fish growing up to 60 feet long. Megalodon's history is shrouded in mystery - much of what we know about this creature comes from fossil records. 

But recent discoveries have given us a better understanding of Megalodon and how it lived. This article will explore everything you need to know about Megalodon: its history, biology, and why it went extinct.

Description and Appearance

Megalodon was the largest vertebrate known to have existed, as determined by fossils of hundreds of teeth and a few vertebrae. Megalodon and modern white sharks appear to have shared a tooth design because of their similar shapes, suggesting that they were relatives. Megalodon may have looked identical to this species. It was a big torpedo-shaped fish with a large pectoral, conical snout, dorsal fins, and a solid crescent-shaped tail.

The statistical link between the size of Megalodon's fossil teeth and the teeth and body mass of modern white sharks and other living relatives is used to calculate estimates of its body length. According to this information, adult Megalodons had a mean length of 10.2 meters, with the most enormous individuals reaching 17.9 meters long.

Megalodon didn't get its name "giant tooth" for nothing. The teeth of this shark specie were serrated and heart-shaped, with some reaching up to half a foot in length, compared to the largest teeth of a Great White Shark, which measure only three inches long.

You'll have to go back 65 million years further than Tyrannosaurus Rex, when there was nothing else but dinosaurs, to find a creature with more enormous choppers. The projecting canines of some saber-toothed cats were in the same province.

Diet

The Megalodon was a top-tier predator that preyed on bigger marine animals, such as whales, sharks, and dolphins. It is thought that Megalodon could have eaten up to 100 tons of food per day.

According to scientists, researchers believe that the Megalodon would first target the tails and flippers of its mammal preys to prevent them from swimming away before going in for the kill. Its 276 serrated teeth were ideal for tearing flesh.

The Megalodon also had a massive bite. While humans have been measured to possess a bite force of about 1,317 newtons, paleontologists estimate that the Megalodon could generate a bite force ranging from 108,514 to 182,201 newtons.

As the world's largest fish and 245 feet long, the largest marine predator ever existed, Megalodon was a top carnivore, or apex predator, in its inhabited oceans. It preyed upon large ocean creatures, seals, toothed whales, baleen whales, and sirenians.

The juvenile Megalodons likely hunted smaller prey, while adults went after larger whales. Mature Megalodons may have been immune to predators, but newborn specimens might have been vulnerable to other large sharks, such as great hammerhead sharks.

Reproduction

Megalodon gave birth to live young. It is unknown, however, whether the mammal was viviparous or ovoviviparous. Young, newly born young already may have been at least 2 meters long, according to body size estimates using juvenile teeth.

The mating habits of Megalodon are not very clear, but the shark species appears to have utilized nurseries to raise its young. A Megalodon nursery was discovered in 2010 off Panama's coast, featuring juvenile teeth from various ages.

This warm-water nursery, according to researchers, gave newborn Megalodons access to a broader range of smaller, more-abundant prey and allowed adults to defend themselves from other predatory sharks better. As the juvenile sharks matured, it was predicted that they would go deeper into the ocean to pursue bigger prey.

After they grew up, few details were known about how individuals dispersed. Megalodon is thought to have had an ecological position comparable to that of the white shark. This has led some researchers to project that Megalodon may have covered territories roughly equivalent in size to the contemporary white shark's range.

Distribution

Megalodon lived in the world's oceans during the Miocene and Pliocene epochs. Fossil evidence suggests that Megalodon preferred warm, shallow coastal waters.

It preyed on other sharks in the warm because it lived in the warm, shallow seas that covered most of the planet during its existence. Every continent except Antarctica has yielded Megalodon teeth.

Evolution

Megalodon's history is shrouded in mystery - much of what we know about this creature comes from fossil records. But recent discoveries have given us a better understanding of Megalodon and how it lived.

The evolution of Megalodon is hotly disputed, as is its relationship to modern white sharks. Louis Agassiz, an American naturalist, geologist, and instructor born in Switzerland, coined the name Carcharodon Megalodon for Megalodon in 1835. This scientific name identified Megalodon until the end of the 1990s when another group of scientists puts it in the genus Carcharocles.

Based on their serrated teeth, some paleontologists claim that Megalodon and today's white sharks evolved in the same lineage. In contrast, others place Megalodon in the megatooth shark lineage that dates back to the Cretaceous time, which was between 145 million and 66 million years ago.

Modern white sharks appear to have descended from lamnid sharks some 5 million years ago during the Late Miocene and early Pliocene periods, according to a 2012 tooth analysis. According to the research, the pattern of serrations and other tooth features shared by Megalodon and modern white sharks might result from convergent evolution. 

Extinction

Megalodon went extinct around a million years ago. Scientists believe that the Megalodon extinction was caused by a combination of factors, including a change in the climate and the loss of prey. Megalodon also competed for food with other large predators, such as whales. As the seas became cooler, Megalodon's food sources dwindled, eventually dying out.

Conclusively, Megalodon was a genuinely awe-inspiring creature, and its size and power are still impressive even after all these years. But what do we know about it? What mysteries remain to be solved? Let us know your thoughts on Megalodon in the comment section below, and feel free to share any information you may have that we haven't mentioned here. Maybe you'll help solve one of history's greatest mysteries.
