Biggest Spider in the World, List of Top-10

Spiders are fascinating creatures that come in various shapes and sizes, with some species reaching impressive dimensions. While many people may be arachnophobic, there is no denying the incredible diversity and adaptations that spiders have developed over millions of years. In this article, we will explore the top 10 largest spiders in the world, showcasing the remarkable range of sizes these arachnids can attain.

Which is the Largest Spider in the World?

The title-holder for the world’s largest spider is the Goliath birdeater, scientifically known as Theraphosa blondi, as reported by National Geographic. This tarantula can grow up to a whopping 11 inches in length and weigh around 6 ounces, making it large enough to cover a dinner plate, according to Guinness World Records.

The Goliath birdeater earned its intriguing name from an 18th-century engraving depicting a tarantula devouring a hummingbird, notes National Geographic. However, in reality, these spiders rarely feast on birds and predominantly dine on arthropods.

In contrast to most spiders, Goliath birdeaters don’t construct webs. Instead, they utilize silk to line their burrows beneath the forest floor, creating a cozy habitat, as shared by National Geographic.

While Goliath birdeaters are venomous, their venom poses no serious threat to humans. In the rare event of a bite, the experience is likened to a wasp sting, and medical attention is seldom required, according to National Geographic.
