Hello everyone! My name is Shark. I'm Megalodon. I live in the sea.

We sharks have an ancient family. It is said that we existed on the earth as early as 300 million years before dinosaurs appeared, and it has been more than 500 million years. Sharks, called sharks, sharks and sand fish in ancient times, are behemoths in the ocean, so they are called "wolves in the sea".

I have a strong bite. I can bite a whale in half. My tail is muscular and my fins are muscular, which can help me move forward. My body is lemon, and my mouth is open. 8 meters. My whole family is a "giant". Dad is 2 1 meter long and mom is 16. 8 meters, I am 13 meters long, and I will continue to grow. Our life span is generally around 30 years.

We still have our own language. I opened my mouth to show that I was hungry, and wagged my tail to show that I was going to sleep. My anti-pressure system is very good, I can dive to the deep sea of 1599 meters, and my swimming speed is amazing, 99 kilometers per hour. I am so powerful that I can drag the helicopter into the water in one jump. I have a keen sense of smell. I can tell when a drop of blood falls into the water.

I slept like a monster, but I was cute. I am still the overlord in the deep sea, and small fish, shrimps and even whales are my meals.

This is me, the fierce shark. Are you afraid of me?
