Megalodon is one of the largest fish known and lived in the Miocene to Pleistocene period, about 23 million to 2.5 million years ago. It resembles a great white shark with a torpedo-shaped body, a conical nose, huge pectoral and dorsal fins, and a powerful crescent-shaped tail. Teeth are one of its most notable features, with the largest megalodon tooth ever found reaching an edge of 18cm and weighing nearly 450 grams. With a strong bite force, the lower jaw can crush a small car. As a top predator, Megalodon mainly preys on fish, baleen whales, toothed whales, manatees and seals.

The Komodo dragon, also known as the Komodo dragon, is a reptile of the giant lizard family and is the largest living lizard. It mainly lives on Komodo Island, Linka Island, Flores Island and other islands in the Lesser Sunda Islands of Indonesia. The skin is rough, dark brown, with bony scales, which can effectively resist attack. Forked tongue, can sense smell, used to find prey. Is the top predator, mainly to carrion for food, will also prey on wild boar, deer, monkeys and other animals. Saliva contains venom and a large number of bacteria that can infect prey through bites and eventually die. It is a solitary animal that only gathers during the breeding season.

Tyrannosaurus was a large theropod dinosaur that lived in the Late Cretaceous period about 74 million to 70 million years ago. It is a distant relative of Tyrannosaurus Rex, mainly distributed in Mongolia and China in Asia. Fossils have also been found in Inner Mongolia, Xinjiang and other places. It is one of the largest carnivorous dinosaurs found in Asia. It has dozens of sharp teeth and strong bite force. The lower jaw has a special joint structure, which gives it an advantage when hunting. The forelimbs are the shortest and smallest in the family Tyrannosauridae, with strong hind limbs and a long, heavy tail for balancing the body. At the top of the food chain, it is a top predator, feeding mainly on large dinosaurs. Vision is poor, but the sense of smell and hearing developed.

It is a giant carnivorous dinosaur that lived in the late Cretaceous period, belonging to the theropod dinosaurs. Fossils were mainly found in Argentina and are one of the largest terrestrial carnivores discovered in South America. Huge in size, comparable to the famous Tyrannosaurus rex. The head is large, with strong jaws and sharp teeth, suitable for tearing prey. The forelimbs are relatively small, while the hind limbs are very developed, supporting its massive body. The tail is long and heavy, and may play an important role in balancing the body and making quick turns. Living in the late Cretaceous period approximately 97 to 93 million years ago, he was the top predator in the ecosystem at that time. They feed on other large dinosaurs.

It is a marine reptile that lived during the Jurassic and Cretaceous periods, belonging to the ichthyosaur order, and was the top predator in the ocean at that time. The body is streamlined with a long and pointed snout, making it perfect for capturing fish and other marine creatures. The limbs have evolved into a shape similar to fish fins, allowing for rapid swimming in water. It can reach a length of several meters and was one of the largest predators in the ocean at that time. Fossils have been found in multiple regions around the world, providing valuable information for us to understand ancient marine ecosystems. Despite having the word 'fish' in their names, ichthyosaurs are actually reptiles with a close genetic relationship to dinosaurs.

It is a large toothed whale belonging to the dolphin family. Known for its unique black and white body color and powerful hunting ability. It is the top predator in the ocean, widely distributed in the oceans around the world, from the cold Arctic waters to the warm equatorial regions. Having a highly developed social structure and complex communication methods, able to use sound for communication and hunting. It is known for its hunting of seals, fish, and other marine mammals, and sometimes even preys on other whales, including small whales and dolphins. It is a curious and intelligent animal that can use tools such as stones to break the shells of shellfish.

It is a type of marine reptile that lived during the Jurassic period, famous for its unique long neck and four paddle shaped limbs. Fossils were first discovered in the early 19th century in England. The body size of the Velociraptor is usually large, with a body length of up to 4 to 5 meters, and some species may even be larger. The neck is very flexible and can easily capture fish and other marine organisms in the water. Their bodies are streamlined and suitable for fast swimming, while their limbs are very suitable for propulsion in water. Although the Velociraptor is considered a top predator, its lifestyle and feeding habits remain a hot topic of research for paleontologists.

It is a giant carnivorous dinosaur that lived during the Late Cretaceous period about 66 million years ago. Known for its enormous size and powerful abilities, it is one of the largest known land carnivores. It can reach a length of up to 12 meters, with an estimated weight between 5 and 7 tons, and has strong hind limbs and shorter forelimbs. The head is huge, with sharp teeth and well-developed jaw muscles, capable of producing strong biting force. It has very sharp eyesight and smell, which makes it an excellent hunter. Although the forelimbs are short, the hind limbs are very strong, able to support their enormous weight and run quickly. He was a top predator in the late dinosaur era, and his fossils were found in North America

It is a tyrannosaurid dinosaur that lived in the Late Cretaceous period, known for its strong physique and enormous size. With a length of up to 9 meters and a weight of about 4 tons, it was the top predator in the ecosystem at that time. The head is huge and has the largest teeth in the Tyrannosauridae family, making it very suitable for tearing prey. The forelimbs are short with only two fingers, while the hind limbs are well-developed with a long and heavy tail, which helps maintain body balance. Fossils were mainly found in Alberta, Canada, indicating that they may have preferred to live in environments near coastal plains and rivers.
