The biggest spider in the world is big enough to cover a dinner plate.
The largest known spiders are the Goliath bird-eating spiders of the coastal rain forests of northeastern South America.
The largest one known, a male collected by a scientific expedition in Venezuela, had, according to the Guinness Book of Records, a leg span of over 11 inches.
According to the same source, the heaviest bird-eating spider known, a female captured in Surinam in 1986, weighed a colossal 4.3 ounces.
That big a spider could easily subdue a bird.
Most birds are much smaller.
Wood warblers generally weigh only about 0.35 ounces, a scarlet tanger about one ounce, and a bird as large as a bluejay only about 3.5 ounces.
