Australia leads the world in its number of resident venomous spiders as well as the strength of their toxicity. However, of almost 9,800 species (only about 3,100 species are named) of spiders in 70 families throughout the country, most are perfectly harmless.
Africa. Millions upon millions of wildlife species call Africa home, and it is no different with spiders. Comprising of different climates and landscapes, just like Australia (except 3x larger), Africa sees some of the world's most venomous spiders.

They do not go out of their way to greet us, even if they are squatters in our homes. At best, they are indifferent, minding their own business and never wanting attention.
The 14 reported deaths each for the funnel web, which can kill in 15 minutes, and the redback, whose venom is even deadlier, exclude anaphylaxis, he said. The funnel web “classically speaking” is considered the world's deadliest spider because it “kills so quickly”.
Sydney funnel-web spider. According to the Guinness World Records, the Sydney funnel-web spider, Atrax robustus, is the most dangerous spider to humans in the world.
There aren't many true spiders in the ocean. The other place on the surface of land where there are few spiders, except in human habitations, is Antarctica. That latter is because there are few insects for the spiders to eat. Antarctica and the Profundal Zone.
We found that perceived fear and disgust of spiders were triggered predominantly by enlarged chelicerae, enlarged abdomen, and the presence of body hair. Longer legs were associated with perceived fear as well; however, the presence of two eyes did not produce any statistical significance in terms of fear.
