The biggest shark in history? The largest shark in prehistory

Megalodon. Megalodon, which means "big tooth" in Greek. The shark is 14 meters long and weighs 40 tons on average.

Some of the vertebrae of the megalodon have been found to be much larger than those of the great white shark, and it is estimated that its maximum length range is 18 meters,[1] weighing 50 70 tons, making it one of the largest predators of all time and the largest fish, but no complete vertebral skeleton fossils have been found to support this hypothesis. Megalodon is perhaps the most powerful creature ever found in Earth's history, with a maximum bite force estimated to be around 20 tons, and its oral bite power exceeds that of a Tyrannosaurus rex, allowing it to crush whales' ribs with ease. Living from the Late Miocene 15 million years ago to the Early Pleistocene 2.6 million years ago, it was the apex predator of the ocean.

They have been hailed by many paleontologists as the most powerful <> in the history of the earth

The megalodon, which feeds on large whales, is about the same size as the one-toothed whale, and it is a little smaller than the blue whale, from the Tertiary period.

The largest shark in prehistory was the megalodon.

The longest shark you can see in Ocean Park today is not more than 10 meters, but the world's largest ancient shark is 21 meters long, this shark lived 20 million to 12 million years ago, and it is even more ferocious and terrifying than the great white shark we see in the movies.

It is estimated that the Megalodon is a metre in length, and from this size, the Megalodon is estimated to weigh up to 60 tons, and assuming the metabolism of the great white shark, the Megalodon is estimated to need an average of 50 in its weight (2,400 pounds) of food per day, which is comparable to that of the largest marine predator in prehistory.

Megalodon habits

The Megalodon can prey on any creature in the sea, but it prefers to prey on cetaceans, other marine mammals are also on its plate, the adult Megalodon hunts in the open ocean, and the juvenile lives closer to the shore, the Megalodon had no natural predators at the time, only the Melville whale, which was also the apex predator of the Megalodon.

The megalodon lived in the vast ancient oceans and was the apex predator of the ocean during its lifetime, and according to the scars caused by the attack of the megalodon found on the whale fossils found in various places, the shark was once widely distributed and is now extinct, and the extinction of the megalodon is still an unsolved mystery.

In prehistoric times, there was a kind of shark that actually fed on whales, and it was the prehistoric giant shark - megalodon. Now let me show you what is so amazing about this shark. The largest shark in prehistory, the megalodon

Megalodon, also known as megalodon, is known as carcharodon megalodon, a Greek word meaning giant tooth. It is a huge prehistoric shark believed to have lived between 20 million and 12 million years ago. Fossil Tooth Megalodon is just a creature inferred from fossilized teeth and some vertebral fossils.

with Megalodon. Similar to other modern sharks, its bones are cartilage rather than bone, creating a lack of fossil bone records. However, the megalodon has about 100 large, hard enamel teeth that have been stored for a long time. These teeth are similar to those of great white sharks and are about an inch long***maximum tilt length*** recent studies have suggested that it is a close relative of the great white shark.

However, this theory of inbreeding has been repeatedly questioned as the result of the similarity of teeth due to convergent evolution. In any case, this method of tooth inference allows us to know that this creature was a predator of gigantic size in prehistory.

It is estimated that the largest size of the megalodon is meters long. From this size, the weight difference of the megalodon is estimated to be 60 tons. Assuming that the Great White Shark is proportioned to the new Chan Dai Qing Tangerine Shea, it is estimated that it needs an average daily intake of 50 1 in 1*** or 2400 pounds*** of food.

From the known prehistoric food chain, it is generally believed that it used whales as food. The average bite force is 28 tons, which is the maximum. In 1995, it was proposed to classify the megalodon into a new genus called Archaeosaurus.

So far, however, the issue of classification has not been resolved. Many paleontologists advocate classification as a genus of ancient sharks, while others with a background in marine biology insist on the relationship between megalodons and great white sharks, and instead classify them as genus Man-eating sharks. Scholars of the genus Archaeus believe that the ancestor of the megalodon is Otodus obliquus from the Eocene, and that the ancestor of the great white shark is Isurus hastilis.

Since the Megalodon is mainly based on whales for food, the sea water at the poles is not suitable for the Megalodon to survive, so the whales can escape the hunt of the Megalodon.

Caused the megalodon to become extinct due to lack of food. Other explanations point to the fact that any impact on the food chain will eliminate predators with huge metabolic demands. Others say that the megalodon is still not extinct and is still alive today.

The largest shark in the world is the whale shark.

The whale shark is not only the largest shark in the world, but also the largest fish in the world, with a body length of up to 21 meters and a weight of more than 21 tons.

Whale sharks feed heavily on plankton and small fish. It is mainly distributed in tropical and temperate sea areas. Mild-mannered. Due to mass hunting, the population has plummeted and is on the verge of extinction.

Introduction

The whale shark is the only member of the genus Whale Shark in the baleen shark family and is currently the largest fish in the world, living in tropical and temperate seas. The name whale shark comes from fish biology, meaning that it is as large as a whale and that they are filter feeders like many whales.

The whale shark is a type of shark, not a whale, belonging to the family Whale Shark of the order Baleen Shark of the class Cartilaginous Fishes, and uses gill breathing. The body surface is scattered with pale spots and criss-crossed pale bands, like a chessboard. It is an oceanic fish.

It lives in the pelagic layer of the warm temperate oceanic sea area, mainly distributed in the tropical and temperate sea areas, and is distributed in the range of 30°-35° north and south latitudes.
