Goliath Bird Eating Spider

Goliath Bird Eating Spider

The Goliath birdeater spider (Theraphosa blondi) belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass and size, but it is second to the giant huntsman spider by leg-span. It is also called the Goliath bird-eating spider; the practice of calling theraphosids "bird-eating" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one eating a hummingbird. It only rarely preys on adult birds.

 The species was officially discovered in 2006 during an expedition to Guyana. It is a burrowing spider, feeding primarily on invertebrates, though it has also been observed eating small mammals, lizards, and venomous snakes (surprise surprise). Fully grown specimens can reach a horrific weight of around six ounces.

The goliath bird eater is a species of tarantula, and has relatively weak venom, which causes mild swelling and pain for a few hours. But the thing that poses the biggest threat to us humans is the goliath’s ability to expel urticating hairs from its body. These tiny, nearly invisible hairs float through the air – and have an awful tendency to stick in the eyes.
