Living out there is something really terrifying. The most lethal shark that the world has ever scene –– Megalodon, the biggest carnivorous fish that's ever lived. And I don't think I need to explain why.
— Allen, describing Megalodon

Carcharodon Megalodon, more commonly known as just Megalodon (name meaning "Big Tooth"), was a enormous prehistoric shark from the Miocene to Pleistocene epochs. It was the largest predatory fish to ever exist and was essentially a giant great white shark.

FactsEdit

Time/Era/PeriodEdit

Megalodon lived from the Oligocene to the Pleistocene from 25–1.2 million years ago. It was the apex predator of the seas during its day. Their extinction was caused by Ice Age climate changes. As the Ice Age began, the whales Megalodon preyed on migrated to colder waters, where the shark could not follow. As a result, Megalodon was doomed into extinction by hunger. However, some paleontologists and other scientists believe that Megalodon could still be alive today in the 21st century.

Megalodon was that largest shark ever to roam the seas, larger than a whale shark, and was not only the largest carnivorous fish ever discovered, but was also that largest predatory creature that ever lived on Planet Earth, rivaling and even surpassing the size of predatory dinosaurs like Giganotosaurus and even Tyrannosaurus Rex as well as other sea monsters like Cymbospondylus, Dunkleosteus, Tylosaurus, Basilosaurus, and even Liopleurodon. Megalodon averaged over 50 to 60 feet (15.3 to 18.3 m) long and weighed more than 12 to 60 tons (24,000 to 100,000 lbs.) However, some specimens have been discovered to have measured in excess of 75 feet (23 m) in length and weighed as much as 70 tons (140,000 lbs.).

Megalodon also had a tall dorsal fin, large pectoral fins and a large and powerful caudal fin but its anal fins were small. Megalodon were basically oversized great white sharks. As such, they had the same overall physical appearance (with darker grey colored skin on top and lighter colored, or white, skin on the bottom, most likely to serve as camouflage), only they were well over three times the size. By the time a adolescent Megalodon reached three years of age, they could have measured just over 20 feet (6.1 m) long and weighed at least 3 tons. Full–grown Megalodon were 20 times the weight of juveniles. They had several rows of sharp, serrated teeth that measured at least 7 inches long within a pair of massive jaws that measuring around 10 feet (3m) wide and could deliver a crippling bite. Megalodon was estimated to have a bite force of around 20 tons, more than enough to slice through flesh and bite through bone. This shark literally had the most powerful bite force in the animal kingdom.

BehaviorEdit

Megalodon were solitary animals as they were large enough to hunt game independently. As essentially giant great white sharks, Megalodon behaved the same way. For instance, much like young great whites, juvenile Megalodon preferred to live in shallow waters away from adults, who hunted large prey in the open oceans. The juveniles surviving in shallow water was partially for their own safety, but additionally they fed on different and smaller species of prey. There, the adolescents would mainly hunt small cetaceans like Odobenocetops. A fully grown Megalodon would hunt larger whales.

But whether juveniles or adults, Megalodon had some of the same hunting strategies as modern great white sharks. Because they didn't want their prey to attack them back, these giant sharks snuck up from under their prey and landed devastating attacks. As relatives of great white sharks, the juvenile Megalodon therefore attacked their prey in an identical way. However, when adult Megalodon hunted, they swam bellow further into the deep, dark oceans in order for them to gain more momentum. Once they gained enough, they swam incredibly fast directly towards the surface to their prey and struck with intensely powerful force.

A special adaptation that Megalodon evolved was a protective membrane which was located at the back of its eyes. When attacking its prey, it would roll its eyes to reveal the membrane. Sight would not be necessary in an attack as its sense of smell would steer it towards its prey. Megalodon's sense of smell was incredibly powerful. They could detect blood from miles away. Megalodon was a species of shark that actually attacked living whales, and even very large ones at that.

Journal Entry Edit

Known as "the Great Shark" by some or "the Tyrannosaurus rex of the sea" by others, Carcharodon Megalodon (Megalodon for short), or "Big Tooth", was the largest shark that ever existed, massive and powerful enough to hunt and kill the giants of the seas, such as other large sharks, colossal squids, and even whales, no matter how large or what species. Because of this, Megalodon has been dubbed as a "Whale Killer."

A shark the size of a jumbo jet with jaws large enough to eat well over a dozen people at once and powerful enough to crush bone as well as teeth roughly the size of a human hand, this was arguably the largest predator the world had ever seen, ruling every ocean on Earth and having no predators or even rivals to fear during its time, save only larger Megalodon.

Overall possessing the same physical appearance as the great white shark, only more than three times the size, Megalodon is said to have behaved the same way. For example, when hunting, they used the dark depths of the ocean to hid and when ready to struck at their prey, they snuck up from bellow at incredible speed and landed devastatingly powerful attacks on their prey.
