The world's largest and most amazing earthworm. What are the sizes of the largest earthworm and where do the largest giant individuals live? Huge worms
The first reaction to the question: “What is the longest animal?”, I want to answer - a giraffe. After thinking a little, you remember about the whale. Some might argue that there is a blue jellyfish that is even bigger. All these are misconceptions. Without any doubt, the record holders in size will be worms.
Until the end of the 18th century, a fairly large type of the animal kingdom was classified under this name. Later, zoologists disbanded it and created a number of new types.
Classification of worms
Today, the Animal Kingdom includes a large group, under the general name - Protostomes, which do not form a separate rank. What are commonly called worms are united by 8 types. Among them - Hairworms, Priapulids, Sipunculids, as well as Gnotostomulids with Acanthocephalans, are of little interest to us. But the remaining 3 are worth paying attention to:
Everyone knows earthworms. These garden workers never tire of plowing the soil, constantly aerating it. Few people have studied the question of what the largest earthworms are. There is, perhaps, no area in the world where these ringed animals are not found. Under favorable conditions they live up to 10 years. Only by the sixth year is this individual able to lay eggs. The larvae appear another year later. All this time they are growing. On the Australian continent there are 3-meter giants. The photos of the world's largest earthworms are simply amazing. At first glance, they can be confused with a snake.
Medicine knows the fact that 17-meter-long worms were removed from the human body. And it's not the biggest
The photo of such a giant is amazing. The wide tapeworm can live up to 20 years, constantly increasing in size. The carrier is deprived of the opportunity to live normally, his body is depleted to the limit. Infection most often occurs through poorly processed fish.
Bull tapeworm
A very unpleasant animal lives in the tropics - the Dragon. The worm reaches humans through water, gnaws through the intestinal wall and settles in various organs. After reaching sexual maturity, females move to the subcutaneous tissue.
As soon as a person is near the water, leaning out, the worm throws out numerous larvae. With age, such animals grow up to 80 cm. Numerous, easily opened pustules form on the human body, which cause unpleasant itching and serve as a site for secondary infection.
Human roundworm
Roundworms also use humans as a carrier. These animals are not gigantic in size, the maximum size is no more than 40 cm. But their fertility is amazing. The female is capable of laying up to 240 thousand eggs every day. Eggs that come out are very difficult to kill. They can wait for their owner for up to 12 years. Under favorable conditions, they do not need an intermediate carrier. The larvae develop well on their own without leaving the egg. They reach humans through poorly washed vegetables and fruits, as well as contaminated water. They emerge from the eggs, to begin with, and begin to migrate through the insides of a person.
The larvae can be found in the heart, liver, lungs and even the brain. They are caused by a wide variety of diseases. After a certain stage of development, they return through saliva to the stomach, where they grow into adult animals. The circle closes.
Disgusting animals that can be both harmful and useful. We're talking about worms. Many, at the sight of this creeping creature, will shudder and squint, while others, on the contrary, consider these creatures cute and do not even hesitate to pick them up. Earthworms belong to the order Haplotaxida, a suborder of oligochaetes.
Belated maturity
The most interesting thing is that giant worms mature quite late, by animal standards. This period begins only in the fifth year of their life. And after another year, they acquire the ability to lay eggs (it is worth noting that worms are hermaphrodites). After another year, larvae emerge from the eggs. Their length is also quite impressive - about twenty centimeters.
What is the purpose of worms? Charles Darwin himself told the world about them for the first time. So, these animals help moisten, mix and aerate the earth. They move in the soil, pushing it away, or swallowing the soil and passing it through their body. Boneless prefer a wet bud, since in a dry one their activity is significantly slowed down, and sometimes stops altogether.
Glowing Monsters
Australians are very happy to be next door to such a giant animal. And this is even despite the fact that during its journey underground the worm makes a kind of snorting noise that is clearly audible to people on the surface. But this is nothing compared to the amount of soil an animal cultivates when making its own burrows.
According to anecdotal evidence, but a generally accepted fact, the longest worms can be found not only in Australia, but also in New Zealand. The length of individuals can reach five meters, and these monsters glow in the dark. Specimens are also found in South Africa. The maximum length of the largest worm was 6.5 meters. He was caught in 1967.
However, mutants have also been found in China. True, their size was not so impressive. In Xipun province, a local resident on the estate of Li Wong discovered an animal about half a meter long. The worm was half-dead and the finder thought it was a snake. However, upon careful study, it became clear that this was an ordinary earthworm. The same one that most fishermen in Russia use as live bait. By the way, as experts said after the discovery, favorable climatic conditions contribute to the high growth of worms, as well as the level of radiation and the amount of harmful chemicals in the soil. Record holders were also found in Russia, cases were recorded in the Urals and the Caucasus.
Longer than a blue whale
It turns out that the longest animal in the world is the tapeworm Lineus longissimus. It can grow up to sixty meters. It turns out that the specimen is twice the length of a blue whale and a third the length of a hairy jellyfish. The tapeworm belongs to the group of nemertean worms, which means “sea nymph”.
Scientists know about a thousand species of such worms. And almost all of them are marine inhabitants. The animals' bodies are long and thin, and can only be two millimeters in diameter. The worms have a unique ability - they can stretch to their full length. If the body is not elongated, then it is about 30 meters. And the boneless one is more like a long huge tourniquet.
The body of a tapeworm is made up of muscles. They pump blood, because the animal does not have a heart. Individuals are considered the most primitive organisms, and at the same time dangerous and voracious predators. In order to catch its prey, the animal shoots a long tube with poisonous sticky hooks. Many of these worms do not differ in color from the darkness of the water depths. However, there are also those that have quite bright colors. Tapeworms recover well from damage, and some even reproduce by dividing into parts.
Helminths
However, the longest worm can have a length that a person cannot even imagine. The Lenius worm lives in deep solitude, literally, at the very bottom of the Atlantic Ocean. They lead a bottom-dwelling lifestyle and roll their bodies into balls. Perhaps in order to leave your entire body safe and sound in the visibility zone, and also so as not to lose control over your oblong body. Lineus are unusually long and thin. They can grow up to 20-30 meters.
Delicious worm
However, there are worms that are not at all disgusting, which you can pick up and even swallow without a shudder. Here we are talking about edible worms. And this is not a creation of nature, but a product of confectioners. Every child has eaten such a marmalade miracle at least once in their life. True, usually the yummy does not exceed 10 centimeters. However, a truly endless delicacy has been invented especially for those with a sweet tooth. The longest gummy worm has grown to a record 66 centimeters. It weighs 1.3 kg. Otherwise, the sweet worm is no different from its relatives.
The largest earthworm living on the planet, according to officially confirmed information, was found in South Africa and its length is about 7 meters!
In our country, of course, such large individuals are not found and an individual 30 centimeters long is considered gigantic. Australia can boast of even larger worms; specimens one and a half to two meters long live there and are quite common!
These creatures can bring both benefit and harm. Very often, when the conversation turns to worms, many people have a feeling of disgust and disgust, while others think that they are cute creatures and are happy to pick them up.
Habitat and life activities
The earthworm is a representative of the order Haplotaxida, suborder oligochaetes. On the Planet they can be found on almost all continents. The only place on earth where they have not been found is Antarctica, since permafrost prevents them from existing and reproducing normally. Typically, the length of these animals varies from 2 cm to 3 m. As we said earlier, the largest representatives of this species live in South Africa and Australia.
Many will probably be surprised, but earthworms are distinguished by their longevity. It is not uncommon for individuals to be about 10 years old. Giant worms, unlike the snakes with which they are sometimes confused, do not pose any danger to humans.
Interestingly enough, the giant worm reaches maturity quite late when compared with other animals. Adulthood begins only in the fifth year of their life. And only after another year they are able to lay eggs. Even the largest worms can reproduce independently without a pair, i.e. they are hermaphrodites. After another year, small worms begin to appear from the eggs, if you can call them that, of course, because their length is very often more than 20 centimeters.
These animals are very useful, their vital activity helps improve soil fertility. They move in the ground, like their usual small counterparts, in two ways. The first is by pushing it apart and the second by swallowing it and then passing it through the entire body. They prefer to live in places with wet soil, since in dry soil their life activities become significantly more complicated or simply impossible.
Australian giant worm
Some people, seeing a huge worm, one and a half to two meters in size, crawling, may be scared, but this is completely in vain, they are completely harmless.
If you ask a simple riddle - it crawls on the ground, about a meter long, up to three centimeters thick, no legs, what is it? Most will say it's a snake or viper. And of course, it’s not a snake that’s mistaken - it’s some of the biggest worms - gypsum worms. This species was found in the Australian city of Gippsland and is considered the largest of all living on the planet. If an adult of this species stretches out, the size of the worm can reach 2 m.
Despite their impressive size and frightening appearance, these crawling giant creatures are extremely gentle. It is quite difficult to find them, because almost their entire lives they are deep in the ground. It has been established that the wetter the soil, the easier it is to breathe. These large worms dig holes at a depth of about ten centimeters. During prolonged rainfall, these large worms can leave their cozy shelters and climb to the surface. In turn, their burrows can be discovered when a landslide occurs.
Long Gippsland worms are quite fragile - careless handling of them can lead to their death. They can only live in a certain type of moist soil.
If you walk on the ground directly above their water-filled burrows, then in response to the noise of footsteps, they can become frightened and begin to move, making sounds similar to squelching and being quite loud. Meeting them is very rare, but if it happens, you will hear.
A large Gippsland worm lays large cocoon eggs, which are similar to brown bean pods. A year must pass before small worms emerge from them. The length of newborns is about 20 cm. They grow slowly and reach their maximum size in about 5 years. It is uncertain exactly how long they live, but some sources indicate 20 years or even a little more.
Despite their impressive size, these worms are few in number due to the fact that their burrows are often destroyed and reproduction is slow. This species is listed in the Red Book.

Megascolides australis(lat.) - a species of oligochaete worms of the family Megascolecidae, common in Australia. It was discovered in 1878 by Frederick McCoy in Gippsland in Victoria. The worm reaches a length of 80 cm to 3 m.
The species is endemic to the area around the Bass River in southern Gippsland. The range covers 40,000 hectares, forming a triangle between the communities of Loch, Korumburra and Warragul. Worms very rarely appear on the surface of the earth. They live in moist soil at a distance of 40 meters from the river bank. In some places they are found very often, up to 10 individuals per 1 cubic meter of soil.
Worms(Gippslands) feed on roots and plant detritus. When in danger, they take refuge in burrows that go 1-1.5 meters deep. Living tunnels are often kept damp. The presence of worms can be determined by the characteristic noise that occurs when the worms return to their homes. Megascolides australis is a long-lived worm with relatively slow metagenesis. Studies have shown that worms reach sexual maturity in their fifth year. For this reason, worms cannot always quickly adapt to changes in the environment.
Worms They are hermaphrodites, but they need a partner to reproduce. The worm lays an amber-colored cocoon with an egg 5 to 9 cm long in chambers adjacent to the tunnel, at a depth of approximately 22 cm from the surface of the earth. From each cocoon, after about 12 months, only one worm emerges.
Gippslands are quite fragile - careless handling can kill them. Only a certain type of moist soil is suitable for them to live. If you walk on the ground above their water-filled burrows, they will react to the vibration from your steps - they will begin to crawl and make squelching sounds that are quite easy to hear. So even if you consider that giant gypsums are quite rare, you will know that they are near you.
Giant Gippslands lay huge cocoon eggs that look like brown bean pods. The worm lays only one egg at a time, and it takes a whole year for it to hatch. Baby giant gippslands reach 18 cm in length and take about five years to grow to their maximum length. It is not known exactly how long they live, but according to preliminary estimates, about 20 years.
Despite their impressive size, there are few giant Gippslands in Australia due to the fact that their houses are easy to destroy and they reproduce slowly. Worms are listed in the Red Book as a vulnerable endangered species.
Australian giant earthworms are protected by the government. An annual festival was even organized in their honor - "Karmai" (as the worm is called by the aborigines).
But that's not all the honors. An attraction museum was built in his honor in 1985. It is a huge 100-meter building in the shape of an earthworm.

But what would he say if he discovered a 3-meter-long worm underground? Meanwhile, such worms are found in Australia. True, no one hooks them - their numbers are already too small, so they are under state protection.
Australian giant earthworm (lat. Megascolides australis) is the largest of all known underground invertebrates in the world. It lives exclusively in Gippsland, a rural region of Victoria with an area of just 1000 square meters. km. And even then, you can’t find it on every corner here - like a real earthworm, it chooses clayey and moist soil to live near water bodies.
Or maybe it was earlier - when the entire south of modern Gippsland was covered with dense eucalyptus forests, giant worms had a place to settle. However, the trees were cut down to make way for agriculture, and the soil itself was constantly disturbed: plowed, seeds planted, fertilized and plowed again. This place became uncomfortable for an earthworm of this size, so it had to settle on the remaining small and isolated remnants of the forest.
An adult individual of the giant Australian worm reaches a length of 2.5-3 meters with a body thickness of 2-3 cm and a weight of about 700 g. It is not surprising that from a distance it can be confused with a long, emaciated snake. However, upon closer examination, the segments characteristic of all earthworms are clearly visible, of which the Australian giant has at least three hundred.
Giant earthworms rarely crawl to the surface - they spend their entire lives in long underground tunnels that they dig themselves. Usually the worm digs the ground with the front part of its body, however, if the soil is too hard, it passes it through the intestines and throws it out in heaps to the surface. One individual can process 500-700 g of soil per day.
It's funny that when moving underground, the giant worm behaves very noisily - it smacks, gurgles or buzzes. And all because the walls of its tunnels are covered with a special secretion that facilitates sliding. Australian earthworms breed in spring and summer. They are hermaphrodites, but require a mate for successful fertilization. After mating, each partner lays eggs in a pre-constructed cocoon.
The eggs of the giant earthworm mature and develop over the course of a whole year. The hatched cubs are no different from their parents in anything except their size. The length of their body, by our standards, is no longer small - 20 cm, but only after 5 years they grow to their final size and begin to reproduce. The maximum lifespan of giant Australian worms is 10 years.
Residents of Australia greatly respect their unusual neighbors. In their honor, they even established the annual international festival “Karmai” (the name of the worm in the dialect of the local aborigines). In addition, in 1985, a hundred-meter museum attraction dedicated to the giant earthworm was built.
