Spiders Have An Apetite To Digest Every Human On Earth

Fear is obviously human nature, it can be of anything, water, height, snake, lizard, or spider. Two European biologists were wondering about the appetite of a spider.

Their question was how much food does the entire spider population eats in a single year?

Martin Nyffeler and Klaus Birkhofer published their estimate in the journal the Science of Nature in early March.

They found that all the spiders in the world consume somewhere between 400 million and 800 million tons of prey in any given year.

That is little frightening, but worst is the amount of “meat” is equal to those 7 billion humans on the earth. Spiders could, theoretically, eat every single human on earth within one year.

It gets horrifying as humans consume about 400 million tons of meat and fish each year.

The biologists provided another way to look at it. The total mass of organisms in a given area or volume of all adults on earth is estimated to be 287 million tons. And that is not tough for spiders to eat.

So, as per as theory, the total amount of food consumed by spiders in one year is more than the total weight of the entire population of the globe.

The estimations are based on research into how many spiders live on a square meter of land for all main habitat types of earth and the average amount of food consumed by spiders of different sizes in one year.

One study estimates that the global average spider density is 131 spiders per square meter.

Spiders could eat all of us and still crave more.

A brick wall

According to Nyffler and Birkhofer, if you weighed every single spider on earth, they’d weigh about 25 million tonnes.

A research says that the Titanic weighed about 52,000 tonnes. So the mass of every spider on earth is equivalent to 478 Titanics. Calculation-wise it would take approximately 2,000 pounds of spiders to consume a 200-pound man in one day.


Though it’s probably never going to happen. Spiders are never going to feast on the entire human population. But still, this study is very scary for human beings.
