The great white shark (scientific name: carcharodon carcharias), also known as man-eating sharks, is the largest carnivorous fish, up to 6.5 meters long, weighing 3200 kg, the tail is crescent-shaped, the teeth are large and serrated, triangular, the teeth are 10 cm long, and the large offensive shark. But because of its particularly large size, it can be considered to be the ultimate predator of the food chain, that is, the highest consumer. Great white sharks are found in tropical and temperate regions of the oceans , generally living in open ocean areas , but often entering inland waters. They prefer to prey on seals, sea lions, and occasionally dolphins and whale carcasses. The great white shark first appeared in the Miocene and is the only surviving member of the genus Man-Eating Shark. Therefore, its survival is very difficult, and it can be said that the existence of every great white shark is a miracle of the evolution of life, just like the dinosaurs of the Cretaceous Period. As the population of the great white shark is decreasing and on the verge of extinction, the great white shark is now listed as a protected species in the world and hunting is prohibited. Considered a marine killer because of its large size and aggressiveness, it was filmed as a film of the same name and made into a game of the same name.
The bull shark is small, the body is relatively broader than other sharks, the torso is large, and the whole body is spindle-shaped. The dorsal side is dark grey and the ventral side is off-white.

The anterior nasal flap is broadly triangular; there is no nasal suscence or tentacles.
Tiger sharks belong to the family heterodontidae , which are characterized by a thick hard spine on the anterior margin of the two dorsal fins , up to 1.4 m long , with sharp teeth on both palates , front incisors, and molars on both sides , feeding on invertebrates such as sea urchins and crustaceans. Tiger sharks are found in tropical and temperate seas in the Pacific and Indian Oceans.
Whale shark, rhincodon typus (smith, 1828), shark of the genus Cetaceae in the family Cetaceae. Whale sharks have only 1 family and 1 genus and 1 species. With a large body and a total length of up to 20 meters, it is the largest fish in the world. The surface of the body is scattered with pale spots and crisscrossing pale bands, like a chessboard. The nostrils are located on either side of the upper lip and appear in the mouth. The teeth are numerous and small, arranged in rows. There are 5 pairs of gill fissures, the gill fissures are large, almost reaching the dorsal and abdominal margins of the body, and the last pair of gill fissures is located in front of the base of the pectoral fin. The dorsal fin is 2, spineless, and the 1st dorsal fin is located in front of the ventral fin and has an fin. The caudal stalk is laterally ridged , the caudal fin is crescent-shaped , and the lower lobes are shorter than the upper lobes. For example, whale sharks, with two dorsal fins, varying sizes, large pectoral fins, located under the third pair of gill fissures, small ventral fins, forked tail fins, wide mouth, terminal position, gill rakers like sponges. It is a marine fish species. Eats large amounts of plankton and small fish. It is mainly distributed in tropical and temperate sea areas, and is distributed in summer and autumn in all sea areas of China. Gentle temperament. Due to the large number of hunting, the number has dropped sharply.
The great blue shark is a common name for the scientific name sawtooth mackerel, which is mostly found in temperate to tropical oceans. The great blue shark belongs to the white-eyed mackerel family, up to 6 meters long, with a sharp snout, serrated teeth, mainly feeding on fish, but also eating carrion, relying on keen senses They can quickly appear around the slaughtered whale.

Basking sharks ( cetorhinus maximus ) are the only species in the family Basking and the genus Basking. It is the second largest fish in the world following the whale shark. Basking sharks are found in temperate oceans around the world. They swim slowly, are generally harmless and rely on plankton for food. They migrate frequently and occur seasonally in certain areas. Like other large sharks, basking sharks are at risk of extinction due to their low breeding and overfishing to supply the world's demand for shark fins, meat and organs.
The six-gill shark is found at a depth of 1400 metres in the Australian Coral Sea. In 2006, the Australian Deep Sea Research project team used the latest technology remote control camera to study and photograph Australian deep-sea species, and found a large number of strange deep-sea species, including the six-gill shark. The six-gill shark is the largest and oldest shark in the world, and hasn't changed since the Jurassic era, 200 million years ago.
The frilled shark ( also known as the pseudoemoid eel , scientific name chlamydoselachus anguineus ) is a primitive shark that is the only shark in the genus Frilled sharks of the cartilaginous fish family Of the family Hexopternosauridae.
