We know more about Mars than the ocean. So far, we have only explored less than 15% of the ocean, and the marine species discovered by humans are less than 1/1 of its actual number. So are there ancient creatures hidden at the bottom of tens of thousands of meters? Is Megalodon, the former ocean overlord, hiding here?

more than 4 million years ago, sawtooth sharks dominated the ocean, and even whales were just a delicacy on their table. Their teeth are about 15 cm long, their mouths can open more than two meters long, they weigh about 3 tons and their body length is about 15 meters. Sadly, because of the climate change, whales came to the cold poles of the sea, and Megalodon, who lived on whales, could not adapt to the cold of the poles and slowly became extinct because of lack of food. So if Megalodon sharks are not extinct, but hiding in the deep sea, what will happen to them? Deep-sea animals generally rely on eating damaged plants and falling animal remains for a living, the most representative of which is whale landing. At the same time, some large animals will store food in their own bodies, which can last for several months without eating.

Therefore, Megalodon sharks can appear at night to feed on some horned sharks or Greenland sharks, and there are some king squid living more than 2, meters under the sea, which can fill their stomachs, but their teeth and bones may not be too hard, which will greatly affect their success rate in hunting, because protein and calcium may begin to be dissolved and decomposed under the great pressure of more than 1, times under the sea floor. For example, the deep-sea snail is the marine life with the deepest habitat that we have made, but it has only flexible cartilage without hard bones, and even some deep-sea creatures are directly transparent.

all deep-sea creatures have an electrolyte molecule that can produce piezoelectric effect, and these molecules can prevent other molecules from being crushed by ultra-high pressure. So if the sawtooth shark really hides in the Mariana Trench, it will also have this molecule in its body. At the same time, in order to keep the body temperature, Megalodon must be warm-blooded animals, and in order to adapt to the darkness, it has either evolved a luminous body like a lantern fish or a pair of big eyes like a squid, and its skin will become more sensitive to feel the changes in its surrounding environment. Fragile teeth should also evolve, and octopus and squid, which are sticky all over, should be prevented from escaping. So, with so many changes in appearance and genes, can they still be called Megalodon?
