More about the biggest spiders in the world

The largest spiders in the world can seem scary, but they’re excellent hunters that have important roles within their local ecosystems. Most of these giant spiders can be found in South America, Asia, and Africa.

Many of them can reach a size of up to 25 centimeters (10 inches) and most of the larger spiders are relatively harmless to humans. There are some exceptions though where a bite may need hospitalization, such as the bite of a Giant Huntsman spider or the Brazilian Wandering Spider as well as the King Baboon Spider. 

Unfortunately, several of these species are popular to have as pets, and while some of them are bred, there is also a huge black market where poachers catch the spiders in the wild and sell them as exotic pets.

Tarantulas are some of the most common types of spiders that are held as pets, and the illegal tarantula trade is worth billions of dollars.
