Megalodon appeared in the late Cenozoic, about 26 million years ago,
and flourished to the beginning of the Pilocene, about 1.6 million years ago.
Like most other shark fossils, the complete skeleton of megalodon has never been found,
and parts of the axon and teeth have been found.
By comparing the fossils found with the teeth of the great white shark and the size of the body,
it is estimated that megalodons have grown to a maximum of 16-25 m.
In addition, one tooth was large enough to cover the palm of an adult male,
and the number of teeth on the upper and lower jaw is estimated to be about 292.
Megalodon was the top predator of the food chain.
It has eaten other large marine mammals such as whales and dolphins.
Megalodon can move not only the lower jaw but also the upper jaw when opening the jaw,
so it is believed that it could cause a fatal shock to the attacked target because it can bite a lot of flesh at once.
Meanwhile, some zoologists and some people believe
that megalodon is still alive and somewhere in the deep sea.
Because 95% of the world's oceans
have not yet been explored.

Wait a moment!
This shark is 'Sixgill Shark'
This shark was called the Sixgill Shark Shark because,
unlike most shark species, it has six gill gaps instead of five.
These sharks usually inhabit the deep seas around 2,400m.
These are terrifying predators in the deep-sea bathyal zone,
where large stingrays, dolphins, squids
and even other sharks can be eaten.
If there is a Great White Shark in the shallow area,
Sixgill Shark is located in the deep 2,000 M area.
These sharks usually move slowly, but can have very fast burst speeds in an instant.
It is known that this shark can grow to about 7m.
hold on!
These sharks are Pacific sleeper sharks
that live within 2,000 meters of water.
The average size of these sharks is 3.6m,
The giant Pacific sleeper shark in this video, filmed in Japan in 1989,
was estimated to be about 7 m (23 ft) long.
Wait!
This is whale shark, the largest fish species on the planet.
This fish is a giant fish with a maximum length of 18.8 meters
and a weight of 40 tons.
However, despite its immense size,
whale sharks are gentle whales who prefer to eat plankton or mollusks.
This fish has been living 60 million years ago, ahead of Megalodon.
The shark, which floated on an Australian beach in 2013,
was about 8 meters long and weighed 2300 kg.
But this shark carcass was known as the Basking shark.
It is the second largest fish in the world after whale sharks
Basking shark can grow up to 15m.
The snout is pointed and has small hook-shaped teeth on both jaws.
However, unlike the terrifying appearance and the huge body,
the nature is gentle and does not attack people.
But it is too early to be disappointed.
Because the cause of megalodon extinction is still unclear,
and 95% of the world's oceans have yet to be explored,
who knows that megalodon is still alive somewhere in the deep seas?
