The world's largest known spider by mass is the goliath bird-eating tarantula (Theraphosa blondi). The species can be found in the rainforests of northern South America and weighs up to 175 g (6.2 oz).

There are reports of an individual specimen collected by members of the Pablo San Martin Expedition at Rio Cavro, Venezuela in April 1965, that had a leg span on 28cm (11). A two year old spider, named Rosi, bred by Robert Bustard and reared by Brian Burnett, also had a leg span of 28 cm (11 in) and weighed 170 g (6 oz) in February 1998. The bird-eating spider is only second to the giant huntsman (Heteropoda maxima), endemic to Laos, which is considered the worlds largest spider by leg span. Extra-large specimens of this species can have a leg span of 30 cm (11.8 in).
