Biggest Tarantula in the World,Goliath Bird-eating Spider

Distribution: The largest species of tarantula in the world, the Goliath Tarantuala (Theraphosa blondi) and the Pink-footed Goliath Tarantula (T. apophysis) are found in Venezuela, Suriname, French Guyana, and Brazil. They are burrowing species. The largest species in the world live in the ground and not in trees (or house rafters). Their extreme size and bulk prevents them from climbing well. The large species in Trinidad, living in trees (and house rafters) is probably an Avicularia species. They are large and fuzzy, but nowhere near the size of their giant cousins.
Description: This hairy coffee-colored spider is truly unmistakable. The Goliath Bird-eating Spider is large and very stocky with a broad carapace, thick legs, and a large abdomen. It is a terrestrial species and has evolved to this large, heavy body type living in the humid burrows of the tropical forests of South America. The leg span is usually up to about 10" (25 cm) but can be up to 12" (30.5 cm). Though the male and female are very similar, a mature male will be more slender and long-legged. They mature at about 10 years and can live for up to 25 years.
