What is the largest spider?
What does it eat?
Where does it live?


goliath bird eating spider


While the Goliath birdeater is definitely the world's largest spider by weight, it is the Giant Huntsman spider that takes the award for being the largest by diameter. The lanky arachnids have a leg span of up to 12-inches (30 centimeters) or as some people describe it "the size of a dinner plate".


World's Largest Spider. The goliath birdeater tarantula of South America is arguably the biggest spider in the world. Watch as one hapless mouse wanders into a spider's deadly trap, and see the unusual adaptations that make the goliath one of nature's deadliest ambushers.


With a legspan estimated to be 50 centimetres (20 in), this would have made Megarachne servinei the largest spider to have ever existed, far exceeding the goliath birdeater (Theraphosa blondi) which has a maximum legspan of only around 30 centimetres (12 in).


The Brazilian Wandering Spider is a large brown spider similar to North American Wolf Spiders, but bigger and possessing a more toxic venom. It has the most neurologically active venom of all spiders, and is regarded as the most dangerous spider in the world.


Unlike other spiders, who are noiseless, the Goliath bird-eating spider can make a hissing noise to frighten off threats by rubbing bristles on its legs together. They will also rear up on their hind legs in a threat position. Their two fangs have poisonglands at their base.


If a person gets bitten by a tarantula, the bite will probably feel a lot like a bee sting, with pain in the area of the bite. It will look like a bee sting, too, with redness and some swelling. Because the tarantula's venom (poison) is weak, it's unusual to have more severe reactions involving other parts of the body.
