Introduction to great white shark:

Carcharodon carcharias (scientific name: Carcharodon Carcharias) is a large and fierce shark belonging to Carcharodon. Commonly known as great white shark, man-eating shark and so on. They are friends of mako sharks and are even more cruel. Large people can be as long as 5.4 meters, with wide caudal fin and quick and agile swimming. The tip of the kiss is like a cone, and there are sharp, large and flat teeth in the mouth.

Man-eating sharks range from the sea surface to the continental slope 1280 meters deep. Lively and good at swimming, with an average cruising speed of 3.2 kilometers per hour. It has a record of attacking ships and humans and is one of the fiercest sharks. Widely distributed in the coastal waters of the world's oceans.

In the long history of the earth, the climate and environment have experienced many changes in temperature and warmth. Megalodon, a giant shark, is sensitive and may find it difficult to adapt to the temperature changes that other animals can adapt to.

Whales with the same huge size, because they belong to mammals, have thick blubber in their bodies to keep their body temperature and have strong adaptability to the environment. When the polar waters get cold, Megalodon sharks can't live there, and whales have a refuge from hunting. If the whale is not caught, Megalodon will starve to death.

And Megalodon sharks don't swim slowly with their mouths open to filter food like blue whales and humpback whales. It is a fierce hunter, with large activity and energy consumption. In order to survive, it must eat nearly 2 tons of food every day. Therefore, it has a high demand for the richness of food. Once food is in short supply, its fragile side is exposed.
