Types of Spiders
Spiders arouse different types of sensations in people, some are afraid of them and others find them attractive. For most people, they are intrigued by the way they weave their webs and their elegant designs. Spiders are divided into different species, some of them are harmless, but on the other hand some of them stand out for their toxicity.
The most outstanding characteristics of spiders is that they have the ability to produce silk threads that will allow them to weave webs in order to hunt their prey. Which once they fall into them cannot be taken off, spiders have an oxoskeleton, which is a kind of armor or shell that forms their body. They also have 8 eyes, although there are some of them that have 6 eyes. Females are usually larger than males. There are several types of spiders in the world and this is where we will show you some of them, so that you can recognize them:
Funnel-web spider (Atrax robustus)
Currently, according to several studies, the funnel web spider or as it is also known Sydney spider is considered the most dangerous spider in the world. Its natural habitat is in Australia, it is considered an extremely dangerous species due to the power of its poison. Its degree of toxicity is lethal for a person, it is also considered a home spider. This is because it has synanthropic habits, the latter means that they live in human houses.
When one of these spiders bites a person, the affected area begins to itch. He also begins to feel a kind of tingling around the mouth, nausea, vomiting and fever are not long in coming. The period in which the person can die will vary between 15 min to 3 days, this will be influenced by the age of the person who was bitten.
Banana spider (Phoneutria nigriventer)
The funnel-web spider and the banana spider compete for the position of the most poisonous spider. According to studies within the types of spiders, these two species of spiders can be found as the most dangerous in the world. Although several scientists claim that this banana spider is the most dangerous in the world. It is best to avoid both species of spiders to avoid possible painful death.
These spiders have unique characteristics regarding their appearance, they have red hairs and their body is dark brown. The natural habitat of this species is in South America, specifically in Brazil, Colombia, Peru and Paraguay. These spiders hunt their prey through their webs (as they all do). Their diet is based on small insects, as they are; mosquitoes, grasshoppers and flies.
Its venom, as already mentioned, is deadly for its prey, however, when they bite a human, it tends to develop a serious condition, leading to death. Several studies have shown that in men they cause erections for several hours. As far as the most serious cases that have been found due to the bite of these spiders are those produced in children.
Black widow (Latrodectus mactans)
Within the types of spiders we find the best known species in the world, which is the black widow. This has an average size of 50 mm, however, the size in males is much smaller than that of females. Their diet is based on insects, such as wood bugs and other arachnids.
Many people think that these spiders are aggressive, but the truth is that the opposite is true. The black widow is a fearful, solitary and not very aggressive animal. They must know that she only attacks when she feels threatened and when provoked. The symptoms of the bite of this spider produce intense muscular and abdominal pain, they also produce hypertension and priapism. This sting is very rarely fatal, but this does not mean that they are exempt from being lethal. They can even cause death in those who are not in good health or who are not in good physical condition.
Goliath Tarantula (Theraphosa blondi)
This type of spider is known as the Goliath tarantula, it measures approximately 30 cm in length. As for its weight, it is 150 grams. It is considered the largest tarantula in the world and can last up to 25 years of life. It is found living mainly in forests and humid areas, that is, they live in tropical environments.
According to studies carried out, this tarantula is nomadic, that is, it is solitary. They only embark in search of company when they feel the need to reproduce. Their diet is basically based on worms, beetles, grasshoppers and other insects. The poison that these tarantulas produce is usually lethal to their prey, but not to humans. In case they are stung by one, they will only present nausea, fever and headache.
Wolf spider (Lycosa erythrognatha)
Another of the most poisonous types of spiders is the Lycosa erythrognatha or wolf spider.

This spider is of the nomadic type. They only attack when provoked or when they are hunting their prey. This spider produces a dangerous poison that destroys tissues, even today there is no antidote for its poison.

The effect or damage it can cause will vary depending on the amount of poison injected.
Redback spider (Latrodectus hasselti)

They can be located in Australia, where they live in dry and temperate places.

Apart from causing blisters in the affected area, these when they burst cause gangrene, that is, death of the cellular tissue.
Yellow Sac Spider (Cheiracanthium punctorium)
