Top 10 Most Dangerous Spiders in The World

10. Hobo Spider

Hobo Spider

The hobo spider is a member of the genus of spiders known colloquially as funnel web spiders, but not to be confused with the Australian funnel-web spider. The medical significance of its bite is still poorly understood and debated. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. Hobo spiders sometimes build their webs in or around human habitations.

9. Camel Spider

Camel Spider

A ferocious-looking spider which measures up to six inches! The Camel Spider is found in the deserts of North Africa and hides from the scorching heat of the sun by dwelling underneath the sand. It runs as fast as 10 mph. This non-venomous spider has a powerful jaw and it measures one-third of their body length. Although lacking venom its painful bite, large size and looks make this spider quite threatening.

8. Yellow Sac Spider

Yellow Sac Spider

Also known as Black-footed Yellow Sac Spider. It is noted for numerous spider bites all over the world. It releases a mild toxin upon biting. Clear off if you happen to encounter this spider because its bite will give you a sharp pain and leaves the injured area swollen with a blister. It is usually present in Canada and Australia. Its 1/4 inch body size and pale-yellow color make this tiny spider very difficult to spot.

7. Fringed Ornamental Tarantula

Fringed Ornamental Tarantula

The name Tarantula originates from an old Spanish dance. Just like its step, you’ll end up jumping around once bitten by this big guy! It is large and usually hairy, which is one of the reasons why people are afraid of them. With an exceptionally potent bite, there is no recorded death yet, it causes muscle cramps in the injured area and possible chest pain. Its venom causes an agonizing pain and needs immediate medical treatment.

6. Mouse Spider

Mouse Spider

Missulena is a genus of spiders in the mygalomorph family Actinopodidae, sometimes called mouse spiders. As of 2016 there are 17 known species in this genus, all but one of which are indigenous to Australia. One species, M. tussulena, is found in Chile. The name derives from an old belief, now known to be false, that the spiders dig deep burrows similar to those of mice.

There is evidence that the bite of a mouse spider is potentially as serious as that of an Australasian funnel-web spider; however, recorded bites by this spider are rare, despite the abundance of some species amid human habitation. Funnel-web antivenom has been found to be an effective treatment for serious bites

5. Six Eyed Sand Spider

Six Eyed Sand Spider

The six-eyed sand spider is a medium-sized spider with a body measuring 8 to 15 mm and legs spanning up to 50 mm, found in deserts and other sandy places in southern Africa. It is a member of the Sicariidae family; close relatives may be found in both Africa and in South America, and its near cousins, the recluses (Loxosceles), are found worldwide. Due to its flattened stance and laterigrade legs, it is also sometimes known as the six-eyed crab spider. Bites by Sicarius to humans are uncommon; there are no proven cases and only two suspected cases where the culprit was never identified. Sicarius bites have been experimentally shown as lethal to rabbits within 5 to 12 hours. The genus name Sicarius is Latin for ‘murderer’, from sica, a curved dagger.

4. Black Widow Spider

Black Widow Spider

Latrodectus is a genus of spiders in the family Theridiidae, most of which are commonly known as widow spiders. The genus contains 31 recognized species distributed worldwide, including the North American black widows (L. mactansL. hesperus, and L. variolus), the button spiders of Africa, and the Australian redback spider. Species vary widely in size. In most cases, the females are dark-coloured and readily identifiable by reddish markings on the abdomen, which are often (but not always) hourglass-shaped.

3. Brown Recluse Spider

Brown Recluse Spider

The brown recluse, Sicariidae is a recluse spider with a necrotic venom. Similar to other recluse spider bites, their bite sometimes requires medical attention. The brown recluse is one of three spiders with medically significant venom in North America. Brown recluse spiders are usually between 6 and 20 millimeters (0.24 and 0.79 in) but may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray. The cephalothorax and abdomen are not necessarily the same color. These spiders usually have markings on the dorsal side of their cephalothorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames fiddleback spiderbrown fiddler, or violin spider.

2. Sydney Funnel Web

Sydney Funnel Web

The Sydney funnel-web spider is a species of venomous mygalomorph spider native to eastern Australia, usually found within a 100 km (62 mi) radius of Sydney. It is a member of a group of spiders known as Australian funnel-web spiders. Its bite is capable of causing serious injury or death in humans if left untreated. The Sydney funnel-web is medium to large in size, with body length ranging from 1 to 5 cm (0.4 to 2 in). Both sexes are glossy and darkly colored, ranging from blue-black to black, to brown or dark-plum colored.

1. Brazilian Wandering Spider

Brazilian Wandering Spider

On top of our list is the Brazilian Wandering Spider. Its scientific name Phoneutria originates from the Greek word “Murderess.” As the name implies, it is the most pernicious spider on earth. Just one bite and it will kill outright if the victim does not receive anti-venom immediately. It contains neurotoxic poison 20x more potent than that of the Black Widow! Losing muscle control is one of its effect which ultimately leads to the cessation of breath. Another awful reaction is the excruciating pain that you will suffer for hours as you die slowly. The spider is known to wander and travel to unexpected places which can catch unsuspecting victims off guard.

These little creatures are dangerous and humans who fear them are often right! But no need to worry too much as the probability of crossing their path is quite slim so don’t be alarmed. If by chance you see one, try to clear off as things might go ugly because one bite will definitely mean a lot of trouble!
