Goliath Bird-eating Tarantula
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. These spiders can have a leg span up to 30cm, a body length of up to 13cm and can weigh up to 175g. Birdeaters are one of the few tarantula species that lack tibial spurs, located on the first pair of legs of most adult males. They are mostly tan to light brown and golden-hued. when threatened, they rub their abdomen with their hind legs and release hairs that are a severe irritant to the skin and mucous membranes. These urticating hairs can be harmful to humans. Despite its name, the Goliath birdeater only rarely preys on birds; in the wild, its diet consists primarily of other large insects and amphibians.
