Which animal in the animal kingdom has a sharp tooth? What are their habits?

Ants have a mouthful of sharp teeth, and it takes about 14 days to go from eggs to small worker ants, going through two stages: larvae and pupa. The eggs are white or yellowish, the overall size is about millimeters, and the shape is like a grain of rice.

The larvae are milky white and have a thin tip, often curved, which can easily be mistaken for being"eggs"。Pupae is the last stage of life, young ants become shorter, do not eat, do not move, at this time will be called pre-pupa. Pupae are initially milky white and then fade to a yellowish-brown color.

They are often put together, and people often get along with"Ant eggs"Confuse.

Most ants are ground-dwelling animals that build their nests on the ground, while arboreal animals build their nests in hollow bamboo, branches, trunks, and grass stalks. Special arboreal animals, such as yellow rake ants and blackthorn ants, make nests by spinning silk from larvae and gluing leaves together. Arboreal ant nests are flat, single- or double-layered, and each chamber is arranged on a horizontal plane; Some are three-dimensional nests, which generally tend to be lower in the vertical direction, more complex in space, larger in area, with good drainage and ventilation means in the nest, and clear classification of each room.

Arboreal ant nests are generally built from the original appearance of plants, and some species will bite their way in the nest and ant chamber.

Ant pheromones are a mixture of ingredients that include the smell of the ants' own colony, a scent that can be applied to their prey, and a scent that is used to communicate with their companions, much like an ID card with **, as well as words and numbers**, which is a collection of many pieces of information. Different ants secrete different pheromones, like worker ants leave pheromones on their foraging paths and prey to call out to their partners and cooperate to bring food back to the nest.

The number and intensity of pheromones secreted by the queen ant is the highest, and the queen secretes pheromones to control the growth and development of the colony, which in turn regulates the functional structure of the colony and maintains its balance. It is precisely because of the pheromones secreted by the queen ant that the soldier ant and the worker ant become stunted and lose their ability to reproduce.

In the animal kingdom, great white sharks have a mouthful of sharp teeth, and great white sharks love to swim around in the sea to catch prey.

Sea urchin. We often see sea urchins sticking to rocks on the beach like a ball of thorns, but few people know that sea urchins actually have teeth. And it is evolved by eating stones, and eventually it can become as sharp as a knife, and it will not degenerate back, and the teeth have the magical effect of self-grinding, which also allows sea urchins to gnaw on stones constantly, and finally dig a nest in the rock that can hide themselves.

Sea urchin is an echinoderm that grows in the ocean. Its hemispherical shell is made up of hard limestone with barbs. Within the body cavity there are five small yellow thick atheroscleromas, encased in shells, called sea urchin yellow.

Sea urchins are mainly found on the seabed, from the intertidal zone to a depth of several thousand meters, and are mainly concentrated in the coastal zone of rocky or sandy seabeds, or are widely distributed or confined to a specific sea area, depending on the species.

The animal with the sharpest teeth is the piranha, a mature piranha with a bright green back and a bright red belly with markings on the sides. Have a highly developed sense of hearing. The two jaws are short and powerful, the lower jaw is prominent, and the teeth are triangular, sharp, and staggered up and down.

After biting the prey, he clenched and tore the meat off with the twisting of his body, and he could bite down 16 cubic centimeters of meat in one bite.

The alternating replacement of teeth allows for continuous feeding, and strong dentition can lead to severe bites. With sharp teeth and a large group of attacking animals, piranha are one of the most notorious animals. During a stay in Brazil, someone witnessed the terrifying sight of a school of piranha tearing a cow to pieces in just a few seconds, although not realistically enough.

Extended information: Piranhas inhabit main streams, large tributaries, wide rivers, and turbulent currents. Adults feed mainly at dawn and dusk and are dominated by insects, worms, small fish, and carrion, although some of their similar species eat only plants and small fish. The activities are mainly during the day, and at noon, they will rest in a sheltered area.

Piranhas are not strict about water quality, prefer weakly acidic soft water, and are suitable for growing at a water temperature of 22 to 28 degrees Celsius. Most of these fish feed in groups, and their staple diet is relatively small individual fish, preying on anything that moves in the water, and is especially sensitive to the smell of blood, and any little smell of blood will provoke a large group of "piranhas" to attack violently.

The animal with the sharpest teeth should be the shark, the shark's teeth are so sharp that it can tear at other deep-sea fish in the sea. The shark's bite force and the sharpness of its teeth allow it to live in the deep sea.

I think the animal with the sharpest teeth is probably a dog, because dogs can gnaw bones, and if something is not chewable, people will say that you are a dog.

Piranha pomfret is also known as piranha, piranha, etc., its neck is short, the skull, especially the palatine bone is very hard, the body is oval, the side is flattened, and the tail fin is shaped.

It should be a shark, some say it's a hyena.

The bite of the hyena is stronger than that of the liger, and the stomach acid and immune function are also very amazing, but when it comes to the sharpness of the teeth, I think the shark is more powerful, and the original words of the shark column of the Discovery Channel "The powerful jaw is full of razor-sharp teeth, enough to kill the prey in an instant" These words are enough to show that the shark's teeth are the most powerful.

The animal with the most teeth turned out to be it, with more than 20,000 teeth, and it is also very sharp.

Sea urchins have very sharp teeth. Shouting postureThe sea urchin likes to stick to the rocks by the sea like a thorn ball slow bucket, in fact, it has evolved by eating stones, and its teeth have the magical effect of self-polishing, which also allows the sea urchin to gnaw on the stones constantly, and finally dig a nest in the rock where it can hide.

Sea urchins move as they feed: if they have plenty of food, they can move more than 1 meter a day; If food is scarce, sea urchins may only move 10 centimeters a day. The movement of sea urchins is carried out by transparent, small, numerous permeation and sticky tubular feet and spines.

Sea urchins are similar to starfish in that they can grasp rocks, while the spines at the bottom lift their bodies to help them move freely. They can be guided by the direction of the step belt at any time without turning their heads. When the sea urchin is reversed, its spines and tubular feet can turn it right.

Piranhas with razor-sharp teeth!

Teeth play an important role in the life course of animals. In order to adapt to the changes in life and living environment, the morphological and functional characteristics of animal teeth are also constantly changing, and different species of animals have formed tooth structures that are suitable for their diet. Teeth are the most important part of carnivores.

The harder and sharper the teeth, the stronger the predatory ability and the higher the status. Do you know the hardest toothed animal in the world? Let's talk a little bit about it.

When it comes to the hardest animals in the world, many people think of lions, tigers, crocodiles, etc., but in fact, the hardest animals in the world must be sharks. This is undoubtedly because the teeth of lions, tigers, etc., are very sharp and hard, while the teeth of sharks are many times harder. Shark teeth have 5-6 rows, and their cusps are posterior spiny, with a high cusp in the center and low cusps on both sides.

Except for the outermost row of teeth as teeth, the rest of the rows are spare teeth. When the outermost tooth is lost, the inrow tooth moves rapidly forward to fill the vacancy and replace the missing tooth. It is this miraculous property that gives sharks the hardest teeth in the world.

Because sharks are highly predatory and often break teeth in the process, sharks constantly replace their teeth as they grow, with each shark replacing more than 20,000 teeth over the course of their lifetime. It is this constant replacement that guarantees the hardness of the shark's teeth. The shark's teeth are the hardest teeth in the world, not only hard, but also have a strong bite ability, with a bite pressure of nearly an astonishing 20 tons!

Sharks' main food is a variety of marine life, including fish and seals of all sizes, and humans who are in front of sharks at certain times will become shark food. We often watch movies and learn that sharks are very ferocious beasts, and the slightest smell of blood will make them gather together and hunt like crazy until they eat all their prey.

Sea urchins have the sharpest teeth. Sea urchins feed on gastropods and other echinoderms, as well as algae.

It should be that sharks have the sharpest teeth, sharks live in the sea, and they live by eating some other fish in the sea, and sharks are relatively large.

<>1. Nile crocodile.

Speaking of Nile crocodile, I believe everyone is no stranger, and it is the largest crocodile in Africa, and it is also one of the crocodiles with a very strong bite. At the same time, his teeth are extremely sharp and can penetrate the bones of large animals, and according to relevant research, the bite force of the Nile crocodile can be as high as 2,268 kilograms.

2. Great white shark.

The great white shark is also currently the most aggressive of all sharks, with a bite force of up to 1,857 kilograms. And 1857 kilograms means that it can easily bite large creatures, and the great white shark is not friendly to humans, and there are more shark attacks every year.

3. Hippopotamus. According to relevant data, the bite force of hippos can be as high as 2000 kg. Although hippos are not carnivores.

But its bite force is indeed quite amazing in the food chain of carnivores.

Among them, if it is an adult hippopotamus carnivore, it will not be easily provoked. If a carnivore needs to attack a hippopotamus, young hippos that are not too defensive and aggressive are also selected.

4. Lion. The lion is already at the top of the carnivore's food chain, so this shows how strong the lion's bite and how sharp its teeth are. And the advantage of the lion is not only the sharp teeth, but also the huge size.

5. Tiger. Tigers and lions are at the top of the carnivores, the tiger is known as the "king of all beasts", it is found all over the world, most of the animals are not its opponents, and the bite force is as high as 307 kilograms. So from this point it is also possible that only tigers also have a mouthful of sharp teeth.

6. Polar bears.

Polar bears are considered to be one of the largest carnivores in the world, and their bite force is also extremely amazing, their eyesight and sense of smell are particularly sensitive, and the bite force can reach 245 kilograms.

The shark has a sharp tooth, and the bite force of the shark's teeth is the strongest, and he can almost bite through three tons of food.

It is supposed to be a great white shark living in the ocean, the bite force of the great white shark is more than ten times that of a human being, and the large shark is huge, and its teeth are larger than other animals.

Bite force ranking.

10th place Lion 452 kg.

9th place snapping turtle 455 kg.

8th place Hyena 460 kg.

7th place Bengal Tiger 465 kg.

6th place Siberian tiger 499 kg.

Fifth place Jaguar kilograms.

4th place Bull shark 590 kg.

3rd place spotted hyena 601 kg.

2nd place Hippopotamus 1132 kg.

1st place Bay crocodile 1905 kg.

There seems to be no uniform standard for the sharpest teeth, and I don't know.

I think the animal with the sharpest teeth is probably snakes, and their bite force is also very strong, and many people are afraid of this animal.

Dragons, tigers, snakes, rats, and other carnivores have sharp teeth.

On the surface, the narwhal's teeth, but if you look at it in some ways, the teeth of rodents are the longest and sharpest, and they grow all their lives, but they are constantly worn out, so they are not necessarily the sharpest.
