Goliath Birdeater | Biggest Spider in the World

The Goliath “Bird Eating” tarantula is the World’s biggest spider.

Its scientific name is Theraphosa blondi, making it a tarantula (Theraphosidae family).

The Goliath spider can be found in South America throughout the Amazon rainforest including Northern Brazil, Southern Venezuela, Guyana, and Suriname.

This massive spider can grow up to 11.5-12 inches in legspan, and can weigh up to 6.2 ounces.

In parts of South America, this spider is roasted with banana leaves as part of the local cuisine.

Like most tarantulas, the Goliath has a defense mechanism known as “urticating hairs.” These hairs can cause pain and irritation on human skin.

Also like other tarantulas, the birdeater’s fangs can pierce human skin. Its bite isn’t considered dangerous, and is generally considered comparable to a bee or wasp sting.

These supposed “bird eaters” rarely actually eat birds, and mostly subsist on worms, amphibians, arthropods, rodents, snakes, lizards, and other vertebrates.
