Publishing their findings in the scientific journal Science of Nature this past month, two European biologists by the name of Martin Nyffeler and Klaus Birkhofer have concluded that spiders eat roughly anywhere between 400 million to 800 million tons of prey in a single year.
For comparison, 7 billion humans consume approximately 400 million tons of meat and fish per year, according to The Washington Post. And the truly terrifying part? The combined weight of all adult humans is 287 million tons… More at ati.
Good to be aware of such possibilities;)
