10 scariest spiders in the world

The brown widow (Latrodectus geometricus), also known as the gray widow or geometric spider, is a species of the araneomorphae spider of the Theridiidae family within the genus Latrodectus, which contains the species known as “widow spiders,” including the most famous Black Widow.

The brown widow is a cosmopolitan species that can be found in various parts of the world, but some scholars believe it originated in South Africa. They are more common in tropical areas and buildings. It has been seen in many areas of the United States, Central, and South America, Africa, Asia, Australia, and some Caribbean islands.

Sydney funnel-web spider (Atrax robustus) is a Mygalomorph spider of the Hexathelidae family. It is a venomous species native to eastern Australia. It is also known as the Sydney Spider (or incorrectly as the Sydney Tarantula).

It was previously classified as a member of the Dipluridae family, although it has recently been included in the Hexathelidae. The male reaches up to 4.8 cm; exceptional specimens up to 7.0 cm have not been found. The female is from 6 to 7 cm. Its color is blue-black or bright brown with velvety hairs in the opisthosoma (abdominal cavity). They have bright, sturdy legs, a row of teeth along the canine groove, and another row in their claws. The male is small, thin, with longer legs.

Atrax venom contains a large number of different toxins, collectively called Atracotoxins (ACTX). The first toxin that was isolated from this spider's secret was -ACTX. This toxin causes poisoning symptoms in monkeys similar to those seen in cases of human bites, which is why ACTX is considered a poisonous poison for humans.

The six-eyed sand spider (Sicarius) is a medium-sized spider found in the desert and other sandy areas of South Africa. He is a member of the Sicariidae family. Its close relatives can be found both in Africa and South America. Due to its flattened position, it is also known as the 6-eyed spider.

Being harmless spiders (despite their frightening appearance), it is very difficult to find data on the poisoning of people who met with him.

At ten millimeters long, the Yellow Spider Sak is relatively small. The yellow spider sac has dark parts of the mouth, as well as a stripe that runs from the side under the belly. The front legs are longer than the other three pairs of legs.

The yellow spider sac is often confused with other species and is easy to miss. During the day, it sits inside a flattened silk tube. During the warmer months, this spider tends to live in gardens, leaf piles, lumber, and tree piles. In the fall, they migrate living quarters.

The population increases significantly in the fall, which may not please the owners of the house in which he settled. This arachnid moves fast. He eats small insects and arthropods, as well as other spiders. This type of spider is known for feeding on spiders larger than themselves and can eat their own eggs.

The yellow spider sac was probably the one that caused the most bites in humans compared to other spiders. The bite of these spiders is very harmful. They can usually bite people in the summer. They can attack easily: they crawl unnoticed on people's skin and bite them without any provocation. Fortunately, most bites are relatively painless and do not cause serious illness.

Linothele fallax is a mygalomorph spider of the Dipluridae family. He lives in South America. The color of both males and females is golden. The opisthosoma is orange in color and has red lines. It is a rather large spider: females of this species reach about 12 or 13 cm, while males are slightly smaller.

Species life expectancy: 4 or 5 years maximum, while males die about six months after reaching puberty.

They have single-joint helikers and are usually endowed with venom glands. Pedipalps are similar to legs but do not rest on the ground. In some species, they serve males, groom females, and as a hitch. At the end of the opisthosoma are rows that push out the cobweb produced by the internal glands.

Cyclocosmia is a genus of mygalomorph spiders of the Ctenizidae family. They were first found in North America, Central America, East Asia, and Southeast Asia.

The abdomen of these spiders is circumcised and ends abruptly in a hardened disc, which has been reinforced with a system of ribs and grooves. They use a similar body structure to prevent them from entering their 7-15 cm vertical burrow when threatened by opponents. Strong spines are located along the edge of the disc.

Sydney Leukopaut Spider is a species of poisonous mygalomorph spider native to eastern Australia, usually located within 100 km (62 mi) of Sydney. He is a member of a group of spiders known as Australian funnel webs. Its bite can cause serious illness or death in people if they do not receive medical attention in time.

Redback spider (Tetranychus urticae) is one of the many plant-eating mites that are commonly found in dry conditions. It is a member of the Tetraniquidos or Tetranychidae family. The mites of this family are capable of weaving webs, so they are often confused with spiders.

It is interesting that for some time scientists were afraid to even inspect these spiders brought in samples, as they were very frightened by their sinister appearance.

One of the first researchers to study Phryns claimed that these spiders can cause severe injuries to humans with their pedipalps, and this can even be fatal.

However, over time, it turned out that all this is just prejudice and the Phryne Scarlet Spiders are completely harmless. They do not know how to bite or cannot harm a person in any way. In addition, they are not poisonous, and their formidable pedipalps are used only for capturing and holding small prey.

False Black Widow is a steatoda spider known in England as the "Noble False Black Widow". As its common name suggests, this spider is confused with the Black Widow of the genus Latrodectus and other venomous spiders of the genus, since it is very similar in appearance to them.

Steatoda Nobilis is native to the Canary Islands. He arrived in England around 1870 on bananas that were shipped to Torquay. In England, this spider is considered one of the few native species that can inflict a painful bite. Most recently, a clinical case of his bite in Chile was published.
