biggest spider in the world
The Goliath birdeater (Theraphosa blondi) holds the title as the biggest spider in the world. This massive tarantula from northern South America's rainforests tops the charts by body mass and length, weighing up to 175 grams (6.2 ounces) with a body up to 13 cm long and a leg span reaching 30 cm (about 12 inches).
Key Measurements
Measured by different criteria, the "biggest" varies slightly:
- By mass and body size : Goliath birdeater at 175g and 13cm body.
- By leg span : Giant huntsman (Heteropoda maxima) edges it out at up to 30cm legs, though much lighter.
These records stem from Guinness listings and wildlife studies, with the Goliath confirmed in Venezuela in 1965.
Habitat and Behavior
Native to swampy rainforests in Venezuela, Brazil, Guyana, and French Guiana, it burrows and hunts ground prey like insects, frogs, rodents, and rarely birds—despite the "birdeater" name, birds aren't common meals. Despite its size, it's reclusive and flees from threats, using urticating hairs for defense rather than biting humans often; its venom is mildly painful, like a wasp sting.
