If spiders across the globe unite, they could eat all humans on earth in a year, study speculates

The arachnid species consumes anything between 440.9 and 881.8 million tons of prey in any given year, which is more than the weight of all human beings combined.

This one is for all the Arachnophobics out there! A recent study has revealed that if the world's present population of spiders ever got organized, they could eat all human beings within a span of 12 months.

Although spiders mostly eat insects, some of the larger species are known to binge on lizards, birds, and even small mammals, the New York Post reports.

Experts said in a report published in the journal Science of Nature that the combined weight of all the food consumed by the world's entire spider population in a year is more than the cumulative weight of all human beings across the globe.


The findings were published this month by Martin Nyffeler of the University of Basel in Switzerland and Klaus Birkhofer of Lund University in Sweden and the Brandenburg University of Technology Cottbus-Senftenberg in Germany.

In any given year, it was found that spiders across the planet consume anything between 440.9 and 881.8 million tons of prey, which means they eat at least as much food as teh weight of all seven billion humans on Earth. On the other hand, the authors noted that human beings consume about 400 million tons of meat and fish each year.

Spiders generally consume approximately 10 percent of their body weight in food per day, which is the equivalent to a 200-pound man eating 20 pounds of meat every day, according to spider biologists.

The total biomass of all adult humans on earth is estimated to be 316.3 million tons. If another 77 million or so tons is added to that figure to account for the weight of kids, it is still not enough to meet the total amount of food consumed by the arachnids in a given year, thus literally exceeding the "total weight of humanity."

To put it in other words, spiders could be hungry even after eating all of us. Having said that, spiders' voracity is actually beneficial for mankind since they primarily feast on bugs. Their hunger means fewer pests in the garden, fewer mosquitoes in the yard and fewer flies in the house, according to The Washington Post.

So till the spider apocalypse is upon us, do check out this trailer for the 1990 movie 'Arachnophobia', which showcases what happens when spiders turn on humans.
