Giant spiders. The biggest spider in the world
Today, there are about forty two thousand species of spiders in the world. The length of the smallest of them, known to science - Patu marplesi - is less than 0.4 millimeter, that is, it is impossible to see it with the naked eye. On average, the size of these animals usually varies from four to six centimeters. However, there are also giant spiders in nature, each species of which is interesting in its own way.
Therafoza Blond - the largest spider on Earth
Most arachnologists studying spiders and arachnids agree that the largest body size of all currently existing species of these animals is the goliath tarantula, also known as Terrafoza Blond. The color of the body of the spider is usually reddish-brown, on the paws there are numerous reddish hairs.
The most giant spider in the world lives in wet swamps and tropical forests of several countries in South America: Venezuela, Suriname, Guyana, Brazil.The length of its torso is 7-9 centimeters, and the leg span of the largest detected specimen reached 28 centimeters.
The tarantula of this spider is called wrongly. The basis of its food is actually made up of mice, small snakes, lizards, butterflies and beetles. He lurks his victim in ambush, then suddenly jumps at her, setting his fangs in motion.
The poison of this spider, which paralyzes small animals, is actually not very dangerous for humans, like the bite of an ordinary bee. As a rule, he does not attack people, except when he is forced to defend himself against them.
In its natural habitat, the bird-eating goliath lives in burrows that previously belonged to small rodents. In captivity, it is rarely found, since its export from the territory of the countries of its dwelling is, as a rule, prohibited.
Heteropod Maxim - the longest leg of spiders
The goliath birdie can rightly be called the world's largest spider, based on its torso size and weight. However, he will compete with a giant hunting spider, or Maxim Heteropod - the owner of the longest leg span. This figure in an adult male of this species can be 25-30 centimeters!
These spiders live mainly in Laos, preferring deep and dark caves, from which they rarely go to the surface of the earth. Their bodies, relatively small in size (up to 3 centimeters in males and 4.5 in females), are colored brown-yellow, and the belly is somewhat darker than the cephalothorax.
Today, science knows very little about them, but they are still being studied.
Australian record holder - giant crab spider
The honor to be called the largest arachnid of the Australian continent belongs to the giant crab spider. Its name is associated with a specific bend of the legs, characteristic of crabs (in some instances, their scope sometimes reaches 30 centimeters). In a different way, these spiders are called hunters, or huntsmen.
As a rule, the color of these creatures is black, brown or gray. The body is fluffy, spines are well visible on the paws. They live under the roots and on the trunks of trees, as well as in mountain crevices, between stones, on the walls of houses. They feed mainly on insects, small lizards and frogs. These prey, these giant spiders are able to with great speed pursue on the ground before sinking into her fangs and immobilize with poison.
Their toxin is moderately dangerous for humans.As a rule, painful edema occurs at the site of the bite, sometimes accompanied by nausea and headache, but for the life of a person the poison does not pose a threat.
Nefila - the most giant spiders in the world, weaving webs
Translated from the Latin word Nefila means "one who loves to weave." This name is the oldest known species of spiders today. The size of their torso is not amazing - it does not exceed 4 centimeters. But in the span of the paws, the largest individuals reach 15 centimeters, which makes Nefil the largest of the spiders able to weave cobwebs.
The distribution of various types of data spiders is huge. They are found in Australia, South America, Asia and Africa.
The networks that these skilled craftsmen "weave" have truly incredible properties. Exceptionally durable and sticky laces with a characteristic golden tint can cover up to two meters. Their fortress is so large that they are able to capture and hold even a bat, a small snake or a bird.
Quite strong poison spiders Nefil is dangerous for people, especially those with a tendency to allergies, but it does not lead to death.The characteristic symptoms — reddening of the skin, blisters, and pain — usually go away within a day after the bite.
Brazilian wanderer - one of the most poisonous spiders
Characteristic features of the Brazilian wandering spider - aggressive behavior and extremely toxic poison. His bite can lead to severe poisoning and paralysis, and in the absence of the necessary assistance will lead to the death of a person. That is why the Brazilian wanderers won ill fame, like giant killer spiders. However, with timely provision of necessary assistance, serious consequences can still be avoided.
These giant spiders (see photo below) sometimes reach 10 centimeters in length. The trunk is elongated, brown, completely covered with small hairs.
Brazilian wanderers do not weave cobwebs and do not have a permanent habitat - they are always in search of their prey. They are found in the tropics and subtropics of South America. They are also called “armed” (due to strong poison and powerful oral appendages) or “banana spiders” (since very often they can be bumped between the leaves of banana palm trees).They hunt at night, mainly on insects. However, they can also cope with some reptiles and birds that exceed them in size.
Zerbal arabian - newly discovered giant spider
These giant spiders have become known to scientists relatively recently. Some sources indicate that they were discovered in 2004, others - that this happened in 2010. The countries in which the zerbala were found were Jordan and Israel, which determined the peculiarity of the name of this species - “Arabian”.
The appearance of the spiders of this type is very interesting: their body is painted in a beautiful yellow or silver color, and long legs shimmer in the light with silver and black shades. At length, the largest specimens of the cerbal arabian sometimes reach 8 inches.
At present, this species of spiders is poorly studied. It is known that zerbaly prefer to live the edges of salt marshes and sand dunes. They are characterized by a nocturnal lifestyle, and the activity is associated mainly with the hot season.
Tegenaria Wall - record holder in sprint
In a different way, tegenaria wall is called a giant house spider.The length of its body is about seven centimeters, and the span of the legs is about three times greater than this value. Not surprisingly, Tegenarii among arachnids are considered extremely fast runners for short distances.
The area of distribution of this species of spiders - Asia, North Africa They are also found in some places in Europe (for example, in England, Tegenaria is often called the "cardinal spider", allegedly because the British Cardinal Wolsey was once horrified by it).
An interesting fact is that although these giant spiders produce spiderwebs, they are absolutely unable to deftly swad prey in a cocoon. Instead, they simply release it in a very thick and even layer. It is curious that in competition for the extraction of tegenaria enters into a fight with his fellows, often even killing them. Cannibalism is also common among these spiders.
The favorite habitats of tegenaria are caves and walls of abandoned houses. Today there are very few of these spiders in nature.
South Russian tarantula - the largest spider of Russia
Mizgir, or Tarantula South Russian, is a characteristic representative of the wolf spider family. The body size of the female of this spider reaches three centimeters (the body of the male is slightly shorter). The span of his paws, however, is considerable - 10-11 centimeters.It is distributed not only in Russia, but also in Central Asia.
Shallow minks in the sand or in the ground, which this spider breaks through itself and lines the inside with cobwebs, are characteristic of the mizgir. In them, he spends daylight, but at night he can go hunting on the surface. Sensing vibrations perfectly, the madamer feels when a small insect approaches its shelter. Having let the prey at close range, the spider instantly rushes at it and kills. In winter, it deepens the mink, and the entrance to it is flooded with earth.
People this tarantula practically does not bite. In the event that the bite occurs, the pain and its effects are comparable to the hornet bite.
Japanese spider crab - the largest arthropod on the planet
In fact, sea spiders, nothing connects with arachnids. This is a special class of arthropods, numbering more than a thousand species. And the largest of them is considered a giant sea spider that lives off the coast of the Pacific Ocean near Japan, at various depths. The size of the body of the largest representatives of this species exceeds 30 centimeters, the claw span of them is truly enormous - it can reach 270 centimeters in length! The weight of this arthropod can be twenty kilograms.
Spider crab feeds mainly on mollusks, as well as on the remains of dead animals. There is an assumption that he is able to live for about a hundred years.
