Giant spiders: what they are and where they live

Giant spiders, which frighten even those who claim not to be intimidated by them at all. Those who suffer from arachnophobia, of course, see all spiders as giants, but there are spiders that are objectively so. Let's see what they are and especially if we risk meeting them even in our country.

Giant spiders: what they are

Taking into account that it comes to invertebrate animals, without bones, giant spiders are almost "miracles" of nature to be observed, even for how they move. To help them, mother nature has provided them with one external cuticle of chitin which is their armor.

It is very rigid, so gradually as i giant spiders become more and more giants, this cuticle must be replaced in a process that we can consider like a moult.

THE giant spiders they usually have eight legs, sometimes even the same number of eyes, eight, and blue blood. It is not a question of nobility, but of blood composition: instead of hemoglobin they have hemocyanin.

Giant spiders in Australia

In Australia as in other parts of the world, we can meet giant spiders, including for example the terrible Australian tarantulas (Phlogius crassipes), also known as whistling or barking spiders because they emit loud sounds by rubbing them front legs against the jaws.

They are also nicknamed bird-eating spiders but they actually feed on insects, lizards and frogs. Other Australian giant spiders are those called "hunters", with legs even 15 centimeters long, hairy, black and poisonous but not for people.

We find equally giant spiders in other parts of the world as well. In Amazonia, for example, we have the Avicularia goliath (Theraphosa blondi), the largest spider in the world in terms of weight: the female can also weigh 175 g which for a spider are many.

Giant spiders in Italy

Those don't live in Italy terrible giant spiders we always think about when we hear about it. This does not mean that the boot is not populated by spiders, we host some 54 families represented by 426 genders and over 1620 species.

THE spiders, however, with record size, they are all native to tropical areas, in America, Africa and Asia and belonging mainly to the family of the teraphosides. The Migali, of course, better known as tarantulas. These are predatory animals, and some species are particularly long-lived as well as giants: there are female tarantulas that reach 25 years old, males only 5.

Giant spiders in the house

Not I wish you to find some giant spiders in the house, and I would say that unless you live in tropical areas or go on vacation, this is not going to happen to you. In general these animals are very adaptable and today they are present in every type of habitat, including the domestic one.

Most of the species, however, especially the giants, prefer rocky environments, with barks, caves and caverns. Buildings and dwellings, offices and cellars may be welcome if they resemble their natural habitat of origin.

Giant prehistoric spiders

Gods giant prehistoric spiders not much is known today, but studies are underway that can help us understand what they looked like and how they lived. For example, research teams have managed to do a hypothesis on the appearance of a spider that lived 49 million years ago and that it had remained "embedded" in a drop of amber.

This is thanks to the 3D technology which allowed to recognize the species of belonging and to reconstruct his body in the smallest details. It is only the beginning of innovative paleontology studies, also thanks to new technologies which will allow us, in the future, to meet the past.

Venomous giant spiders

Among the best known giant spiders, there are none particularly poisonous. Some tarantulas, the largest, have a dose of poison in them body that is similar to that of a wasp. If we wanted to hypothesize, on display, i venomous giant spiders, in Italy, it would be a business because there are laws that limit their arrival and presence.

Giant spiders in a dream

THE giant spiders they can be scary, even without reason, even when they are harmless, even when you only dream about them. After the fright, once awake, the curiosity comes to investigate what is the meaning. In general, the presence of a spider in a dream signals a hidden fear or a real but difficult to identify problem.

“The spider, like all cold-blooded animals, it has the function, in the dream symbology, of expressing contents that are incapable of becoming conscious most of the time ”Jung wrote, confirming that it is quite difficult to understand what a spider in a dream means to us. Let's explore some examples.

When one feels disgust at the sight of the spider, this animal becomes a favorable symbol, a sign of patience, tenacity, industriousness and ingenuity. A black spider represents unclear or evolving situations, a red one represents a great passion by which we feel oppressed. A very large spider is a sign of ever-increasing anxiety. If in the dream we crush the spider we are freeing ourselves from an uncomfortable and problematic situation while if instead of the animal there are cobwebs, we have the feeling of being trapped in a situation we would like to get out of.
