The largest captured crocodile in the world. The largest crocodile alligator in the world: size in meters, weight, name, habitat

Crocodiles are the most ancient creatures on our planet, it is known that they have been living for 83.5 million years, when dinosaurs still lived on our planet. People are afraid of these predators and try to stay away from them. Crocodiles have fangs, so they can chew.

We bring to your attention a list of the largest crocodiles on Earth.

Sharp-snouted crocodile reaches up to 4 meters in length, reaches an adult 335 kg. The speed of their movement on land reaches 10 miles per hour, on water they can move up to 20 miles per hour. This type The crocodile poses a particular danger to humans. Sharp-snouted crocodiles do not like low temperatures, therefore, with extreme temperature drops, mass extinctions of the species can occur. Such cases have taken place.

Crocodiles of this species feed mainly on fish, which, in turn, produce the hygiene of the crocodile's body. Even sharks are afraid of this species when crossing in a common area.

The diet of the black caiman contains such dangerous representatives of wildlife as anacondas and piranhas. They are about 3.9 meters long. and weigh about 350 kg. This type of crocodile is not particularly aggressive towards humans, but is still considered one of the most dangerous. Black caimans live mainly in lakes and rivers, females are always smaller in size than males. They prefer to eat fish or turtles, they can also eat snakes.

The combed or saltwater crocodile (Crocodylus porosus) named Cassius is considered the largest living representative of the detachment.

Cassius was recognized as the largest crocodile in captivity in 2013 (5.48 m). The record holder weighs about a ton (998 kg). He was caught in 2011 in Australia. At the moment, the animal is about 100 years old. His full name- Cassius Clay. It was named after famous boxer Muhammad Ali (born Cassius Marcellus Clay).

Cassius received the title of the largest crocodile after the death of the previous record holder - the Lolong crocodile, which reached a length of 6.17 meters. Lolong also belonged to the species Crocodylus porosus. Its representatives can live for more than 100 years, grow up to 7 meters and weigh more than a ton.

Sarcosuchus imperator is considered the largest crocodilian ever to have lived. Individuals of this species lived in Africa 110 million years ago. The last fossils were found in the Sahara desert. Scientists suggest that for 50-60 years, crocodiles managed to grow up to 11-12 meters in length and gain up to 8 tons of weight.

Reptile predators have always evoked a sense of fear and awe in people. Crocodiles occupy a special place in this niche, because their body shields and huge frightening mouths really look frightening. It is known that today crocodiles, or rather their intellectual abilities, have not been fully studied. Many scientists suggest that such predators are not able to think, their habits are controlled only by instincts inherent in nature. However, others, carefully trying to understand the world of reptiles, are convinced that crocodiles are endowed with remarkable intelligence. How else to explain that these predators possess such a developed and, perhaps, the most time-honed skill of disguise and concealment until the right moment?

As for other aspects of the study of predatory reptiles, much is known to science. For example, the weight, length of crocodiles, their natural species, the unique structure of the pupil. But in this article we will talk about the maximum size in length of such a dangerous predator and factors that can significantly affect this value.

combed crocodile

The combed crocodile (Crocodylus porosus - lat.) is considered one of the largest reptiles in the world. It lives in fresh and salt water in the Philippines, in southeastern Asia and in the Solomon Islands. The main feature of this reptile is two crests on the head, located symmetrically with respect to the eyes, and a unique body covered with many pointed tubercles of various sizes. It is because of such natural features that a dangerous predator can be called a bumpy, sea, brackish or spongy crocodile.

Most often, individuals of this species have a belly color from yellow to dark sand. The brightness depends on the age of the crocodile: the younger the predator, the brighter the color. The main color of the entire upper part (occipital, dorsal and caudal) is dark olive or olive brown. The length of the crocodile, which keeps in fear not only animals that live with it in close proximity, but also people living in the vicinity of water bodies, is simply amazing.

Individual sizes

Many are very surprised when they find out what is the maximum length of the combed crocodile. In recent decades, in nature, such predators have grown only to sizes of 5.0-5.5 meters in length with a weight of 500 kg. Usually, a newly hatched cub weighs about 70 kg, and subsequently one head of an adult male drags on all 200 kg. It is worth noting that this freshwater detachment has almost the most pronounced sexual dimorphism. Male crocodile crocodile males are usually twice as large, heavier and stronger than females, which, in turn, reach only 2.7-3.4 meters in length and weigh from 70 to 150 kg.

However, such dimensions cannot be considered accurate, because the length of the largest crocodile, caught more than one century ago and having characteristic pointed growths on its powerful back, was about 10 meters, and the weight of an individual fluctuated around 3 tons. This giant was an exception to the rule for scientists, showing that under certain conditions a predator can become a truly awesome giant. In general, since then such giants could no longer be found. There were individuals smaller and shorter. Therefore, the fact that the combed crocodile has a length of 7 meters is considered reliable. It is up to such maximum sizes that some males of this species are currently able to grow.

Weight

The weight of an adult reptile predator (male), which includes a crocodile, can range from 400 kg to 2 tons. The most important factors that affect the mass of a particular representative are the age and length of the crocodile. A young male will always be lighter than an adult predator of the same size. However, it is known that captive crocodiles gain weight faster than their free relatives. Also, weight also depends on the physique. For example, individuals living in Sarawak, Malaysia) have relatively short tails, which is why they weigh a little more than Australian tuberous crocodiles.

Scientists' conclusions regarding the maximum size of crocodiles

The length of the combed crocodile largely depends on its population, health, genetics and nutrition. This proves the study of Australian scientists. They caught males of this species, which lived in different conditions and habitats. It turns out that representatives of such predators, who had a permanent habitat, grew up to 4.31 m and weighed from 408 kg. Nomadic reptiles could not boast of such dimensions. They reached a length of only 3.89 m and weighed only about 350 kg.

The five longest crocodiles after combed

There are a little more than 20 species of crocodiles in the world. Among them, along with the combed one, which is considered the longest in nature, there are some more individuals that deserve mention:

The Nile crocodile, whose males can grow up to 5 m in length.
Orinoco crocodile with maximum performance at 4.5-5.0 m.
Sharp-snouted American crocodile, the size of which is from 4 m.
growing in the wild up to 4.7 m. By the way, there is evidence that in the reserves it was possible to feed such beauties to almost 6 m in length.
- 4.0-4.5 m.

Hard Facts

Experts always argue about the maximum size of creatures that once lived on Earth, because it is difficult to determine, for example, even the length of a crocodile from the preserved remains (bones and skin). This method in itself underestimates the overall length of the creature, because one has to compare the ratio of the size of the skull and the skin, which is dried. This suggests that at the time when the predator remained alive, it was still longer, at least 10 cm, and there is no need to talk about the maximum. One thing is clear, that more than 100 years ago, real giants lived on our planet, the size of which can only be speculated now.

Crocodiles live long enough to gain enough weight to become the top of the food web in their ecosystems. A ton or a little more - is that not enough to fight a buffalo, an elephant or a man? A deadly rotational jerk - and the crocodile not only grabbed the victim, but also tore off her head.

big crocodiles

Among these animals there are amazing species, they not only reach huge sizes and weights by the standards of predators, but also live for a very long time - more than a hundred years. To date, it is believed that the combed - a giant crocodile, the Nile - a little less, and the Orinoco crocodile and false gharial - take third place. Although the sizes of the caught males have recently been almost the same.

All these types of large crocodiles are cannibals. They feed on everything that they can grab, watch for, drag under water.The Nile and swamps can themselves become prey for the ridged (marine), therefore they prefer living where it is not necessary to share the territory with a combed one.

Description of the giant crocodile - combed

Various sources call this monster differently: Indo-Pacific crocodile, combed, estuarine, Crocodylus porosus, sea crocodile. It is the largest reptile in the world and is at the top of the food chain. The length of males can be up to seven meters, but today's individuals rarely reach a size of 5 meters. Females are much smaller, their maximum length reaches only three meters. The weight, respectively, of males is maximum from a ton to two, females - up to 150 kg.

D for comparison: the weight of the Nile crocodile and its size is slightly less than that of the saltwater crocodile and is 4 meters in males with a weight of more than 400 kg.

G the tin of the combed crocodile is very long and wide: the maximum known ratio of length to width of the base is 76 cm to 48 cm.

In the center of the muzzle down to the snout from the eyes two ridges descend, hence the name - ridged.

This species of crocodile begins the journey of life at just 28 centimeters long and 71 grams in weight. A year later, it already weighs two and a half kilograms, and the length is one meter.

In Crocodylus porosus pronounced sexual dimorphism. Males are considered sexually mature at 16 years old with a length of 3 meters, females - a little earlier - at 12-14 years old, with a length of 2.0-2.1 meters.

The weight of a giant crocodile, however, like all other species, does not increase linearly, but exponentially: a male 6 meters long will weigh twice as much as a five-meter one. With age, crocodiles add less and less in length, although weight may increase. It depends on the habitat (availability of food). Dominant males weigh more than normal males, as they have the opportunity to feed on a larger territory.

Habitat

Salted crocodile, perhaps the only one of all the others, when choosing a habitat, travels for a long time in sea water. Crocodiles marked with radio beacons swam up to 400-500 km in a few weeks. Moreover, they use the power of the current, simply drifting along it, while maintaining energy. According to observations, saltwater crocodiles can interrupt swimming, waiting for a favorable current for up to several days.

According to the descriptions given in the sources, the marine crocodile is less social than other species, more intolerant of its male relatives, protecting females from them, and shows much more aggression.

In the daytime, the reptile takes more sunbathing and bathes in the water. At night, the giant crocodile hunts.

Although the crocodile is monstrously huge, it cannot be called clumsy: it is wildly active and fast, literally flies out of the water during an attack on the victim. When swimming, it can reach speeds of up to 29 km per hour, although not for very long distances. The usual speed when cruising between islands, coasts, along rivers is up to five kilometers per hour. If the crocodile is in shallow water, where it can both swim and run, it will not leave the victim a chance for salvation, no matter how fast it may be.

Judging about the development of the brain of a giant crocodile with its relatively small size (only 0.05% of its mass) can be done by how it literally studies the places of entry into the water and migration routes, depending on the season of its future victims.

How combed crocodiles hunt

Techniques used Crocodylus porosus for hunting are similar to all other species. Usually they circle silently around the intended victim, then attack it with a sharp jerk, either swallowing it right away, or more dragging under water to drown or crush. On land, unlike the Nile crocodile, combed ones were not observed hunting, although their method of knocking macaques off the land with their tails and “cutting” reptiles, lizards, birds, and mammals sitting on them from low-lying branches is known.

A feature of the hunting of saltwater crocodiles (as well as others) is that their teeth can only grasp and squeeze the victim, but not gnaw it. Small animals are simply swallowed, but large animals are dealt with differently - literally “unscrewing” pieces from it by rotating around its axis or in huge jerks.

Features of the structure of the jaws of a crocodile

When grasping, the jaws clench as tightly as they can clench in any known animal. Usually, the gripping force of a crocodile is compared with the recorded bite of a spotted hyena - 16 kilo Newtons versus 4.5.

Proven to be the result anatomical structure jaws of a crocodile. As a result of evolution, the muscles for closing the jaw have developed unusually in crocodiles, they take up a lot of space and are hard as stone. But the muscles for opening are weak and small, so after being captured by live crocodiles, the muzzles are pulled together with just a few layers of adhesive tape.

Life of crocodiles in captivity

To date, many zoos exhibit crocodiles, especially in Australia, where the population of combed species is traditionally large.

In the Philippines in 2011, a giant combed crocodile was caught.

The capture was initiated by local residents, they suspected this male of the death of a fisherman and a girl, in addition, he constantly hunted buffaloes.

As soon as he was noticed (after three weeks of observations), one hundred people of local residents went fishing together with hunters. This happened on September 3, 2011. He was dragged with great difficulty to land, he pulled out three times until the reptile was securely tied up.

He was measured at the zoo, he was listed in the Guinness Book of Records (as a crocodile living in captivity). Lolong is a giant saltwater crocodile, its dimensions are 6.17 meters, 1075 kilograms. At the time of the measurements, he was about fifty years old.

In captivity, the crocodile, named after one of the hunters, lived until February 10, 2013. Died of pneumonia and cardiac arrest.

The local authorities could not decide what to do with the dead crocodile, so he lay in a deep freeze chamber for a long time.

Today it is kept in the Manila National Museum of Natural History.

The largest crocodile in the world today is the combed crocodile. Males can grow up to seven meters in length and weigh one ton. Unlike males, females, the largest species of crocodiles, are not as big.

They weigh only up to half a ton, and grow up to a maximum of three meters. And, interestingly, these giants can now be seen quite often while walking in Indonesia, Australia and the islands of New Guinea.

Salted crocodiles live in freshwater reservoirs, and here they prefer to breed. However, the reptile feels quite comfortable in salt water. Therefore, sometimes the largest crocodile in the world can even displace sharks from coastal waters. It is worth noting that, as a rule, young individuals live in brackish water, which, in turn, were forced out of their usual place by adults. Saltwater crocodile males periodically fight for territory.

The name of the crocodile "combed" is quite simply explained. The reptile has two ridges, which are located in the area of \u200b\u200bthe eyes. Well, the color of the animal changes with age. For example, in a young individual, it is light yellow, and there are spots and dark hairs on the surface. In older relatives, the color is darker. And the belly is distinguished by a light shade, more often white or yellow.

Strong and ruthless

Eats the largest crocodile in the world prefers small fish, reptiles, birds, and large reptiles. But these are juveniles. Adults consume completely different foods. Their menu includes large crabs, turtles, monitor lizards and snakes. Often seasoned crocodiles prey on cattle, in particular, antelopes, buffaloes, wild pigs. And reptiles guard their victims at dusk, when the crocodile is not visible. Food is waiting at the watering hole when it does not even suspect anything. The victim instantly falls into a vice, the strength of the jaws of the crocodile is so great that the bones of the cattle are immediately crushed. After being captured, the beast immediately finds itself under water and is unable to resist.

World's largest crocodile ate 50 people

Reptiles also attack people. Quite a few cases are recorded every year. And it's all human negligence. The crocodile attacks shallow water where, as a rule, a relaxed vacationer swims. However, there are also attacks on land, however, they are quite rare. And, according to experts, usually attacks are provoked by aggression on the part of people.

Maternal instinct

Males become sexually mature at the age of 16, females - much earlier, at 12 years. Salted crocodiles breed exclusively in autumn and winter. The female lays about 50 eggs in a hole and buries it. Inside such a nest, the cubs are together with mud and leaves, which maintain a comfortable temperature in the pit. Three months later, crocodiles are born. The female, usually, is close to the cubs and closely monitors their development, as soon as the mother hears the voices of the children, she begins to tear the hole and help the offspring hatch. However, females are sometimes not too vigilant and eggs become the prey of predatory animals. One way or another, only one percent of the offspring usually survives to puberty, because young individuals are also eaten by other predators.

most valuable

The skin of combed crocodile is incredibly valued in the market. Therefore, over the past 70 years, their numbers have declined significantly. In some countries, the reptile is completely destroyed. A large number of Crocodiles can be found in Australia. At least 100,000 people live there.

Filipino record holder

Some time ago, a huge crocodile was caught in the Philippines. Its length was 6.4 meters, and its weight was more than a ton. According to local residents, before the discovery, they began to notice the constant loss of livestock. Then, people began to disappear. After some time, it turned out that the crocodile, which lived in the local area, was to blame for everything. The animal was caught, however, people did not tell anyone about the details of the process of capture. However, there it was not possible to find out whether the caught crocodile is a cannibal. Since there are many predators in the Philippines, they do not mind eating human meat. By the way, it was decided not to kill the captured champion. He was sent to the local zoo to attract tourists.

Sarcosuchus

And at the beginning of the Cretaceous period, the crocodile sarcosuchus lived on the planet. He lived in Africa, and ate fish and herbivorous dinosaurs. For a long time, nothing was known about sarcosuchus, but in the middle of the 20th century, a paleontologist from France, Albert-Felix de Lapparent, discovered the teeth and armor shields of this animal in the Sahara, and later another researcher found six skeletons of an ancient sarcosuchus at once. Therefore, we managed to find out that this crocodile was most likely the largest of all crocodiles that lived on Earth. The body length of the sarcosuchus was 12 meters with a mass of more than 8 tons. Now parts of the body of a predator are stored in one of the Parisian museums.

The biggest alligator

But the largest alligator, which managed to catch, has grown to 5.8 meters in length. It weighed over one ton. Found it on Marsh Island in Louisiana in America. It is noteworthy that next to the record holder there were still quite a few large individuals, but, nevertheless, of smaller sizes.

It is immediately worth noting that it is not difficult to distinguish a crocodile from an alligator. The crocodile has a more elongated muzzle, in addition, a large tooth is visible on the upper jaw. There are only two species in the alligator family. American and Chinese. They live, respectively, only in the USA or China. And the latter is now on the verge of extinction. American alligators can be found in a number of areas of the country, in Florida alone there are more than a million individuals. By the way, alligators are bred specifically for the sake of meat and valuable skin.

At first glance, alligators may seem slow. But this is far from true. At short distances, the reptile can develop an amazing speed - up to 45 kilometers per hour. So a person, with all the desire, cannot run away from a predator. Young individuals feed on insects, snails, small fish, crustaceans. Adult alligators eat birds, turtles, big fish and, sometimes, carrion. They can attack adult animals. But predators are afraid to attack a person. However, for the sake of protection, they step over fears.
