Arachnophobia, the fear of spiders, is a common phobia among humans. And when it comes to big spiders, the fear can escalate to a whole new level. In 2024, despite advances in technology and understanding of the natural world, some of the largest arachnids still roam the Earth. Let’s take a closer look at the nine biggest spiders still crawling the planet:
1. Goliath Bird-Eater (Theraphosa blondi)
The Goliath Bird-Eater holds the title for the largest spider by mass. Found in South America, particularly in the Amazon rainforest, this tarantula can have a leg span of up to 30 centimeters (12 inches). Despite its name, it rarely preys on birds but is known to eat small rodents, insects, and even frogs.
2. Brazilian Wandering Spider (Phoneutria spp.)
Known for its aggressive behavior and potent venom, the Brazilian Wandering Spider is another giant of the arachnid world. It can have a leg span of up to 15 centimeters (6 inches) and is found in tropical South and Central America. Its venom is considered to be one of the most toxic among spiders.
3. Huntsman Spider (Sparassidae family)

Endemic to the rainforests of Colombia, the Colombian Giant Tarantula is one of the largest tarantula species in the world. With a leg span of up to 25 centimeters (10 inches), it is an imposing sight. Despite its size, it is generally docile and rarely poses a threat to humans.

Rounding off our list is the Australian Golden Orb Weaver, known for its impressive webs and striking yellow coloration. While not as large in terms of body size, its leg span can still reach up to 20 centimeters (8 inches), making it one of the largest orb-weaving spiders.
Despite their intimidating size and appearance, most of these spiders are relatively harmless to humans and play important roles in their respective ecosystems. However, encountering one in the wild can still be a hair-raising experience for even the bravest of souls.
