While you are sitting on your couch, enjoying an interesting show or lying on bed reading an engrossing book, there is a strong possibility that a spider is staring at you with all its eight eyes from a dark corner.
Yes! It is possible.
A recent entomological survey of homes in North Carolina has revealed that there are spiders in all of them.
Spiders mostly feed on insects, however, some of the giant species also snack on birds, lizards and small mammals. Given their ravenousness, profound meals and large population on the planet, two biologists from Europe were inspired to calculate the total food eaten by all the spiders in the world in a single year.
And the results were more than shocking!
According to the estimates in the journal ‘The Science of Nature’, Martin Nyffeler and Klaus Birkhofer have affirmed that, in any given year, the world’s spiders consume prey between 400 million and 800 million tons. This means that spiders can eat meat equivalent to the weight of at least 7 billion humans.
The total biomass of all adults on the Earth is somewhere close to 287 million tons. Adding to it another 70 million tons, the approximate total weight of all children on the planet, it still does not equal the total weight of food eaten by spiders in one year.
That means spiders could gobble up the entire human race and still remain hungry!!
A lot of sophisticated estimation was done by Martin Nyffeler and Klaus Birkhofer to arrive at this conclusion and a number of other fascinating facts were revealed during the process.
If all the spiders on earth were gathered up and placed on a huge scale, they would weigh about 25 million tons, equal to 478 Titanics!!
But the good part is that the voraciousness of spiders actually works for the good of mankind since they snack on bugs and not humans.
