What is the weirdest fish in marine life?

The most prosperous era of marine life is Ordovician, which is called the Fish Age.

Their remains are generally turned into land because of crustal movement, and their remains are excavated on land.

Ancient marine life

First place: black dragon, black dragon, lived at the end of Cretaceous, at the same time as the famous Tyrannosaurus rex. When Tyrannosaurus Rex dominated the land, black dragon also dominated the ocean. There are many kinds of black dragon, the largest of which is 18 meters long. It is fierce and gregarious. They feed on sharks, swordfish, ancient turtles and even other black dragon. If there is anything more dangerous than meeting a black dragon in the ocean at the end of Cretaceous, it is meeting their families.

Second place: the smooth-faced odontosaurus lived in the ocean of Jurassic (65.438+55 billion years ago-65.438+45 billion years ago), and it was the largest and most dangerous beast that ever existed on the earth. It can grow up to 25 meters at most, and any other kind of life in the ocean may become its food. Because the swimming speed of Pterodactylon is not as fast as that of black dragon, the relative risk is reduced. Tooth dragons with smooth sides like sharks.

Third place: Megalodon knew from its name that this creature had huge teeth. Megalodon lived in the warm ocean 4 million years ago, when human ancestors just learned to walk upright. Megalodon sharks are 15 meters long and feed on large whales. When the ice age came, whales migrated to polar waters. Megalodon, which lost its food, became extinct.

Fourth place: The mechanical toothed whale (Wang Long whale) lived in the Sahara desert 36 million years ago, but it was still a warm ocean at that time. The mechanical toothed whale is 18 meters long, feeds on other whales and large sharks, and even dives into swamps at high tide to feed on archaeopteryx. The El Ni? o phenomenon intensified, and after the glaciers appeared in the Antarctic continent, the mechanical toothed whales that lost their food gradually became extinct.

Fifth place: Dungeon Fish, an armored metamorphosis fish, lived in Devonian 450 million years ago and ruled the ocean for about 50 million years. Dungeon fish is about 9 meters long and weighs 4 to 5 tons, weighing two or three elephants. The headgear of the dungeon is about 5 cm thick. Dungeon fish feed on other kinds of soft-shelled turtles.

Sixth place: Cupid ichthyosaur Cupid ichthyosaur lived in the Triassic period 230 million years ago, when the first dinosaur coelomosaur just appeared. It is 8 meters long.

Seventh place: Nautilus Nautilus lived in the Ordovician 450 million years ago and was ten meters long.

in addition

swordfish

This giant fish can swim at a maximum speed of 60km/h and is ready to attack.

Age: 87-65 million years ago in the late Cretaceous.

Natural enemies: sharks like Cretoxyrhina.

Feeding habit: meat

Typical body length: 6 meters long

Introduction; Swordfish has a dark blue back and a bright silver belly as its upper and lower camouflage colors. A sharp tooth and a strong tail make it a powerful pursuer. Swordfish swim under the sea. It preys on other large fish, including a 2-meter-long fish, and is ready to pounce on seabirds on the water, such as a floating yellow bird. However, the most important thing is that swordfish is a great swimmer, and its speed can reach or exceed anything in the ocean at that time. It may be able to jump out of the water and help it get rid of parasites on its skin. However, it is not invincible. Once injured, its huge size means that it is easy to be found and become a victim of sharks.

Chest shark

A strange fin made this early shark stand out from the crowd.

Time: 370-345 million years ago, from Late Devonian to Carboniferous.

Natural enemies: dungeon fish

Feeding habit: meat

Typical body length: 0.7-2m long.

Introduction: The chest shark is similar in size to modern sharks, except that its incredible dorsal fin-ironing board shape-is only found in males, so it may be part of the sexual display. The top of the dorsal fin is covered with rough dentate scales, which echoes the skin of the nose and mouth of the breast shark. Is this used to imitate a huge mouth and make this creature look more terrible? Breast sharks usually swim and feed in shallow waters near the shore. Its food includes small fish, crustaceans and cephalopods (such as ammonites). There is evidence that breast sharks may migrate and return to specific places to mate and breed. It must be able to swim fast, though not fast enough to avoid the hungry dungeon.

Lizi fish

Time: Late Jurassic10.65 million-10.55 million years ago.

Natural enemies: sauropods, crocodiles, bow bream.

Feeding habit: meat

Typical body length: 27 meters long

Introduction: Leeds fish is a huge fish, which can make all other animals in the ocean look short, but it is a gentle giant, feeding on zooplankton such as shrimp, jellyfish and small fish. It may swim slowly across the upper water body of the ocean, inhale a mouthful of water rich in plankton, and then screen them out through the huge mesh plate at the back of its mouth. Its eating habits are similar to those of modern blue whales, which only feed on plankton. They may travel long distances to find a place in the world where plankton will gather into nutritious thick soup for seasonal reasons. The Jurassic ocean where Liz lived is still a dangerous place. Despite its huge size, it has no special defense measures against carnivores, such as odontosaurus and ground crocodiles. One attack may not kill adult Leeds, but several predators can cause fatal damage.

Grand Yang Long.

Age: Late Cretaceous from 85 million to 65 million years ago.

Typical body length: 3 ~ 4m long.

Long-necked dragon

When the tail is bitten, it can also be broken by itself, and they will take the opportunity to escape.

Time: Late Triassic, 235 -2. 1 100 million years ago.

Typical body length: 6 meters long

Magic dragon

Amphibious killer of carnivores

Time: Triassic 240 million -2 1 100 million years ago.

Typical body length: 3-4 meters long.
